Crushing Machinery: The Past and Present

machine learning articles


In China, there had been the most simple crushing tool – ball and socket in 2000 BC. From the 200 BC to 100 BC, the crushing machinery – ball and socket further evolved into the foot pestle. These tools using the leakage were the initial prototype of the crushing machine, but their action was still intermittent crushing.

The earliest crushing machine with continuous crushing action was invented by the Lu Ban living in the late Spring and Autumn Period. The other with continuous grinding action was the roller grinding machinery, it appeared later. 200 AD later, Du Yu and other Chinese had developed the water-mill based on the foot pestle, and the water was the driving force, which improved production efficiency to a new level. These machines were used for grain processing, but also extended to other materials on the crushing operations.

Modern crusher had been created after the gradual improvement of steam engine and electric motors. In 1806 there appeared steam engine-driven roller crusher. In 1858, Blake, in the United States, invented the jaw crusher. Rotary crusher was developed in 1878, the production efficiencies was higher than the jaw crusher with intermittent crushing action. In 1895, American William injected impact crusher which was lower energy consumption.

Meanwhile, the grinding machinery also had a corresponding development. In the early 19th century, ball mill had been widely used. Rod mill with uniform size of the discharge was invented based on the development of ball mill in 1870. In the 1930s, Americans and Germans had developed a roller bowl mill, roller mill and other vertical shaft mill.

With the development of technology, so far crushing machinery development has made considerable progress. Especially after the 1990s, crusher production and sales increased rapidly, while the number of enterprises continued to increase. These enterprises could produce 30 ton vibrating crusher, 24 ton static roller crusher and 30 ton tire crusher and other range of varieties of products. They had self-development and production of complete crusher manufacturing system, and the gap with international advanced level was gradually narrowing. Therefor, crushing machinery industry was entering a new period of development.

In the twenty-first century, there are a group of outstanding enterprises in the crushing machinery industry. In these companies, you can see the latest development of crushing machinery. A lot of experts who are dedicated to advanced research and development of crushing equipment have developed crusher with international technical standards. Some high-quality products are as follows: jaw crusher , impact crusher, cone crusher, mobile crushing plant, high pressure suspension grinder, sand making machine, and the production line with the feeder, vibrating screen and a full set of aggregate conveyors.

Your Guide to Office Machines and Accessories

machine learning articles


Equipping your office with the right machines and accessories is vital in ensuring that your staff work as effectively and productively as possible.

The following guide will highlight some of the equipment you should look out for and what you should consider when buying it.

Fax machines

Despite the advent of the Internet and the popularity of email, many businesses still rely on fax as an effective form of communications. Therefore, a fax machine is still an important consideration to make when kitting out your office.

Many modern fax machines are combined with other devices such as phones or photocopiers, these multi-function machines are especially popular for those who are on a limited budget, or those who have limited space in the office.


Photocopiers allow you to make copies of documents quickly and easily. They are one of the most common and popular office machines. You might need to consider whether you need a huge photocopier, or whether a smaller desktop model will suffice.


When choosing a printer, the main consideration is whether or not you want to go for an inkjet or laser machine. For smaller businesses, inkjet printers are cheaper in terms of equipment outlay, however, the cost of refilling and replacing cartridges can soon mount up.

Although more expensive in terms of equipment, laser printers can make more sense financially due to the fact that consumables are cheaper and last longer. Because of this, larger businesses may find that laser printers, and even color laser printers are the more cost-effective solution in the long run.


Computers are probably the most important machines you will need in an office. Very few modern businesses can function without them, and they are for most nothing short of essential. Office computers are sometimes very different in specification from the computers we use in the home, specifically specifically for tasks such as word processing, email and spreadsheets.

When choosing computers for your office, you need to decide whether you want desks or laptops, the difference between these is especially that desks are static machines which sit at a desk and can not be moved, whereas laptops are more portable and can allow workers to work remotely. Laptops are therefore a good option for businesses who employ staff who travel around a lot and often take work home. Although they are more expensive they allow businesses to work more flexibly and so be more productive, effective and efficient.

Other accessories

There are a host of other office accessories you can purchase to make life easier for your staff and help your business to run more smoothly. These include binding and laminating machines, shredders, data storage devices and whiteboards and projectors. You'll also need to remember that paper, and other office supplies are essential to the smooth running of the modern office.

Now you know more about modern office equipment, now now is the right time to make sure that you have got the right office machines and accessories you and your staff need.

Online Courses – The Best Learning Solution For Working Professionals

Free Technical Stuff


Working professionals as a group of people are probably the keenest of all learners. They are acutely aware of their strengths, shortcomings and are forever looking to better themselves. Any added advantage is good for them and education becomes the easiest avenue for them to immediately sharpen their skills and improve on their weaknesses. As a working professional, it is extremely important that they understand and appreciate the merits of online courses as a solution to their query.

Time's Not a Problem Anymore

How many of you are so excited when you sign up for a new course or workshop only to miss the very first day because your boss decided to call a last minute sales target meeting. Online courses are accessible from any part of the world, as long as you have a computer and a decent Internet connection.

Specialized Course Content

Traditional education employs a one-course-fits-all mentality. Inevitably, even though you might find value only in a part of the course, you are forced to take the entire course because you have no other choice. Online courses are successful because they can narrow down the focus to suit only particular niches. The advantage there is you get exactly what you want and you pay for just that.

Far More Cost Effective

What very few people realize is that when they are paying for a six hour course on-ground, they are not just paying for the instructor to teach them and for the instructor to correct their papers but also the rent of the classroom, electricity, cleaning charges, otherwise called overheads. The same course online will be available at a fraction of the cost because the instruction is created only once. And there will never be a time when server space rental is comparable to real estate. So you end up paying only for the instructor to correct and review your work.

Of course there are going to be restrictions to online courses. The only way to actually test if you have learnt anything is through assignments. And, in their current form, there will still be subjects where online courses will not be able to match up to a real-life version. Dancing, cooking, martial arts, painting are just some of the courses where an online avenue will not work because it would be a little difficult to submit your painting or your four course dinner for review. But for the rest, at least for now, online courses serve as an immense boom for working professionals looking to improve learn something new.

Corporate Training – Is It The Best Option?

Free Technical Stuff


Effective management and employment of this asset is even more critical in today’s business climate and highly competitive environment. In a tough economic climate with unrelenting pressure on training budgets, companies, today, are increasingly demanding reduced time-to-production. Further, training vendors are constantly challenged to demonstrate the value, R.O.I and business impact of training initiatives. For organizations, the challenge is to keep the skills of human capital updated within reasonable budgets. It is, thus, imperative that when a skill augmentation/update is required, a suitable training vendor is engaged that can deliver Complete Learning Experience while reducing Total Cost of Learning.

The rapid changes in technology landscape, coupled with vast array of technology options available to professionals, are making corporate training requirements increasingly complex and challenging to manage in-house for the Learning & Development Managers. These demands make corporate training a totally different ball game as compared to retail training delivery. The scenario today is different, with an increase in awareness of corporate training in Indian industry; a gradual shift from general to specific approach has been realized. This translates to moving to “tailored” in-house/customized training, as opposed to open house/ public training courses. With the high churn rates that IT companies in India are witnessing, training today is considered as a retention tool than a cost, by most managers. Despite the current challenging market, that the ongoing need for qualified IT personnel in an Asian Pacific will fuel major opportunities for IT training and certification in the region and estimates that around 1.5 million IT experts will be needed by 2012.

Key drivers for this longer term growth include enhancements in collaborative tools and technologies, backed by increasing Internet penetration to deliver online content. Although majority of the employed IT professionals hold relevant “qualifications”, the industry still faces declining numbers of qualified and skilled manpower.

A corporate training delivery must be process oriented, understanding business drivers behind the training requirement, scoping the delivery content requirements, assigning subject matter expert/industry consultant as a trainer, pre-training assessment, preparing trainees, delivering business specific customized course, post-training assessment and follow-up/ assistance.

The process must be supplemented with training life-cycle management – planning, management, administration and advisory. This must relieve Learning & Development Managers from the rigor of organizing and managing the training’s – they must be focusing on understanding the learning and development needs of the employees; not spending their time and effort in nuances of organizing and facilitating a training.

Learning About Accredited Online Degree Programs

machine learning articles


College has never been more expensive, and a degree has never more been more beneficial to finding a job. This combination has warned many people from advancing in their careers or from pursuing further education. A number of online degree programs have come into existence to help people that can not afford the time or money for college or a degree program, but unfortunately not all of them are a good bargain. Those who are interested in online degrees need to make sure they find an accredited program – programs that have been evaluated and approved by licensing organizations. Otherwise, the student may find himself out of money and with no valid degree to show for it.

How Online Degrees are Structured
Online degree programs can vary, but in general they follow the same basic structure. Classes are taken online through the computer, although the student may need to purchase textbooks or other materials. There is a real instructor who records or live-streams classes to students, and is available to answer questions through e-mail or video chat. Students interact with each other through chat rooms and message boards, and all assignments and tests are submitted to the instructor electronically. Some online programs will require students to show up to labs or physical classes for lessons occasionally. How many classes a student can take at once or how often the class meets is determined by the program, but most are designed to fit into a student's busy schedule.

Costs of Online Degree Programs
Online degree programs are usually significantly cheaper than traditional degree options, but they are not free. Programs differ in how expensive they are, but many can be arranged so that students pay by class or term session instead of being responsible for a large lump sum payment. The base of the cost is tuition, and it may be due at the beginning of the semester or the program, or be payable in installments. On top of tuition, there may be other fees such as registration or material costs, and all require access to a computer and internet. Financial aid is available from most accredited programs through the school or the federal government to help offset these costs.

Different Types of Programs
Online degree programs vary from basic certificates of study to masters level degrees. Very few require a prior degree for associates or bachelors degrees other than a high school diploma. There are many areas of study available as well including traditional liberal arts, sciences, design and specific career paths such as paralegal, criminal justice, medical assistance or transcription and others. Aside from the different areas of study, some programs will require a larger time commitment or that students take multiple classes at once or in a pre-determined order.

Repair Curriculum For Sewing Machines Repair

Free Technical Stuff


Three years ago, I began work on a training program to equip sewing machine repair technicians. In an industry that historically produced new technicians through an informal apprenticeship styled watch and learn process; developing a comprehensive training program loomed large. When I graduated from college, I launched into my public school teaching career. I complete my masters degree in education, and served as a learning specialist in Maryland for several years. For over thirty years, I had to develop curriculum and lessons on many different topics as a minister. My education and experience led me to believe I could develop a quality curriculum to train technicians.

Sewing and sewing repair have been the focus of our family business for nearly twenty years. Translating experience into lessons, coursework, and practical curriculum is a doable challenge. What do technical prospects need in order to successfully learn the information and skills to repair sewing machines? There is a vast amount of information involved in repair. To make the content understandable presentations should implement good learning theory. The course should provide instruction, application, technical support, and access to resources.

Instructional contents of the curriculum includes easy to read instructions with illustrative photos, charts, and illustrations. The course is broad in scope requiring less more focused courses. Each smaller course has its own textbook to present the necessary information on mechanical sewing machines, advanced sewing machines, antique sewing machines, sergers, embroidery machines, and business development. The curriculum employs fundamental program design including textbooks and workbooks. The student reads the textbook, tests their understanding by filling in the workbook, and reviewing their results for solid learning.

Since people learn in different ways, several resources are added to the program to enhance the learning experience. Audio presentations and instructional videos help expand the learning process. Bonus materials are also included to provide answers and practical resources.

Reading, listening, even watching content presentations, I did not consider enough to assure success. I believed that practical application is also essential. With this in mind, a detailed practiceum calls for the students to perform a dozen actual services and repairs on real sewing machines. The student acquires the sewing machines from various sources to give them practice. They take digital photos and submit their results for evaluation.

Following the completion of each ecourse an exam is completed and submitted. Then a final certification assessment is also taken. Reference and support resources are also an important part of the program. These make training faster, easier, and more effective. Are there secrets that unlock student learning? Curriculum design must also consider the principles of learning. Student experience, receptive learning style, multiple presentations, doable application, and testing greatly affect the overall learning experience.

The student must be able to read and perform basic mechanical activities. They also need to understand the basic operations of the sewing machine. Since many would have technicians have never actually used a sewing machine; a special sub-course on the secrets of sewing is provided to the student. While this sub-course is not required, it is vital for the student to understand the use of the sewing machine before attempting to service them.
Repeat, repeat, repeat. Going over the same principles, ideas, and concepts again and again insures that they are learned. The curriculum is designed to drum these core ideas through until mastered. The end result is a comprehensive curriculum with focused sub-courses to insure learning is mastered for each area of ​​specialization. Students use their eyes, ears, heads, and hands to learn ingredients of the course.

Six Study Tips For the Online Learner

machine learning articles


How in the world do you block off time between running around behind the kids, cook dinner, do laundry, prepare for work the next day, sit in unmovable traffic, and attempt an A in a distance learning course? Your study skills are challenged, you have limited time to sit down and prepare resources for a discussion question or a test. So what do you do, you strengthen your study skills with these six easy steps:

1.) Ask family or friends for help. Many of you who have children will absolutely need to heed this advice. As a mom myself, it's hard to set an hour or two a couple times a week to devote to studying, posting discussion answers and submitting assignments. So, who helps? The spouse and my parents. So parents, who are doing a great justice to your professional growth by pursuing an education online, you need help to manage the children, especially the smaller ones.

2.) Read assigned chapters at least 30-45 minutes a day. Use a highlighter to capture important points. Read over any sentences that may stump you. Write notes or questions to the side that catch your attention to refer back to later.

3.) If there are important concepts to learn or theories to master, make a chart or table to compare or contrast the concepts for the unit your class is working on.

4.) Application of learned concepts. What's the use of learning something if you do not know how to apply them to real life? Write examples on how you would use the concepts on a daily basis or scenerio.

5.) Work the questions at the end of the chapter, even if they are not assigned. This will help you with Tip # 4.

6.) Do your best to not study in bed or when you are the most tired. You will not get anything done and you will instantly feel sleepy because you are in a comfortable state. Try a kitchen table or a desk, get some good lighting and play very soft music without words to stimulate your mind. This will help you retain information much better.

Bonus Tip ***: Use additional resources that the instructor lists in the syllabus.

Make a routine of your study time, try to find out when you are most alert and motivated. For example, I am a morning person. My study times are mostly done around the morning hours, because at night, I usually set aside time for clients, household duties, and writing articles. Find your time where you are studying effectively. But most of all, make sure you master your learning experience.

Free Technical Stuff


Most of the ABA approved paralegal courses will follow a curriculum that will be tailored towards giving the participants the necessary studies and skills which will enable them to be able to get working opportunities as lawyers assistants.

Through such approved courses, you will find that once you are through with them, you will have gained skills such as client interviews, research, drafting of legal documents and small legal related services.

Another advantage of the ABA approved paralegal courses is the fact that one can benefit from the pre-law specialization which can be helpful if you want to advance your education in law.

In institutions that have this course, you will find that the duration of the course is normally between one or two academic years. In these schools, you will also find that internship will be mandatory.

Schools that have this type of certification can be found online or offline through the Standing Committee on Paralegals Directory of ABA approved Paralegal Education Programs.

This can be helpful to know since there are more than one thousand institutions which are offering paralegal courses. Going through each of them so that you can be able to determine the ones that are offering ABA approved paralegal courses can be quite a hassle.

Although these approved schools are the best in that they meet certain certificates, it is not mandatory by law that any school offering paralegal courses should be approved by ABA.

The institutions that have the accreditation will always have a higher image outlook than those that do not.

The reason behind this is the simple fact that schools with the accreditation will be known to have a higher standard of learning than those do not.

This is because of the fact that once a school has been ABA approved, it will be monitored by the said body not only to make sure that they have the standard but also to ensure that the standards are maintained.

That is why those individuals that are interested in doing paralegal courses will be advised to do ABA approved paralegal courses.

This will also give them a higher chance of employment as a result of the recognition that employers give to those who have done such courses.
