With scientific and technological development, especially in electronics, information technology, rapid development, more and more high-tech applied to the machinery manufacturing industry. Especially in recent years in China has become our familiar word, but, in China almost become synonymous with poor quality products, which can be seen that our product quality to be improved, which depends largely on the our manufacturing process. Industrial countries over a wide range of high-precision machining, precision machining, micro-machining, micro-mechanical and micro / nano technology, laser processing technology, electromagnetic processing technology, super-plastic composite processing technology and processing technology and other new processing methods.

High dependence on foreign technology , resulting in the development of China's machinery manufacturing industry, controlled by others. China's dependence on foreign technology up to 50%, while the United States, Japan is about 5%, the ratio in developed countries are generally below 30%. And self-sufficiency rate of China's key technologies, representing about 40% of investment in fixed assets investment in equipment, there are more than 60% rely on imports to meet, the key high-tech equipment is basically dependent on imports. Especially since the reform and opening up, more and more foreign companies to invest in China, China has introduced a number of foreign advanced equipment but did not grasp the core technology. The industry believes that China's machinery industry, there is a huge technological 'black hole', the most prominent manifestations of the high dependence on foreign technology.

China's mining machinery manufacturing industry for many years, and now use their own design 'heart' a little, and it makes a lot of mining machinery industry whom trouble. But now there are several mining machinery manufacturing enterprises started to pay attention to design their own main brand products. It is noteworthy that many key areas, especially outside the field of defense technology dependent, would pose a serious challenge to national security. As a national high-tech Industrial Development Zone window, there is 57% of technology from abroad. The industry generally believes that technology is state of black hole formation and the degree of emphasis put into closely related. Countries in the past two decades ignored the development of machinery industry, policy, and funding has gone wrong. The most typical example is the state-owned enterprises. State-owned enterprises on the creative talents of the property is basically no incentive to implement, and property rights stimulate innovation and R & D system is an important guarantee for the product. R & D technologies and products, or taken away without compensation by the state, either free copy by other companies. Take the example of China's mining machinery manufacturing industry.

What you need to do when the ball mill enters the belly bulge?

Ball mills are crucial equipment for grinding after materials are crushed. It is an efficient tool for grinding various materials into powder.

With regard to the use of Ball Mill belly bulge appeared in the process, there are several factors:

Firstly, to see whether the ball mill to the mine mouth spit normally expected, if not properly spit expected, is likely to lead to bulging belly ball mill;

Secondly, listen to the sound of the ball mill; if the smaller changes the sound stuffy, it is very possible to be ball bulging belly;

Then, look at the current ball mill control cabinet, so they think that when the current value is likely to become larger mill expansion belly of the precursor is in fact not the case, if the ball bulging belly, its current value is become small. So we need to pay more attention to operating the ball mill correctly.

Grate type Ball Mill has a grid plate at the discharging end which has many holes for putting minerals pulps out easily. At the discharging end where the grid plate is close to, it is equipped with lifting device for mineral pulps which is radial shape strips. These strips divide the area between grid plate and the end cover into several fan-shape chambers, which lead to the hollow shaft. When a ball mill runs, these strips function as lifting the pulps that is, lifting the mineral pulps up to the hollow shaft through the hole on the grid plate. And then the pulps is sent out of the ball mill through hollow shaft. In a word, this type has the characteristics of discharging the mineral pulps by force and of high production ability.

This type of ball mill is usually applied in the first-period of grinding operation and it can get a higher capacity. But, its output product the size is bigger than that of an overflow type ball mill.

1). Frame

The frame is made of tetra-wall rigid steel plates opening up and down. The frame is used to support the eccentric shaft and withstand the crushing force. It is required to have enough strength and stiffness. Generally, it is casted integrally by cast steel. For small machine, the cast steel can be replaced by high-quality cast iron. For large machine, the frame should be casted section by section and then connect the section together by bolts tightly. The casting technique is complex. Small home-made jaw crusher can also be made by welding thick steel plate, but the rigidity is poor.

2). Jaw plate and side plate

Both fixed jaw and movable jaw are composed by jaw-body and jaw plates. The jaw plates are the working part which is mounted to jaw-body with bolts and wedge. The jaw body hung on the shaft is the front wall of the machine frame. Mostly it is made of cast steel or cast iron because it required to be strong and rigid enough to withstand the crushing force.

3). Driving eccentric shaft

Driving eccentric shaft is the main shaft of crusher. It is made of high carbon steel and has a huge torque force. Eccentric part requires fashioning, heat treatment and the liner of bearing to be casted with babbitt metal. One end of the eccentric shaft is mounted with pulley and the other end is mounted with flywheel.

4). Adjusting device

There are generally wedge block type, pad plate type and hydraulic type etc. adjusting devices, normally wedge block type is adopted which are composed of front wedge and back wedge two wedges, front wedge block can move forward and backward and block against rear push plate. Rear wedge plate is adjusting wedge which can move up and down. The slant sides meet together and adjust outlet opening size by screw moving up and down. The adjusting of small size jaw crusher outlet opening size is realized by increasing or decreasing the washers between push plate bracket and machine frame.

5). Flywheel jaw crusher

Flywheel is for storing energy not consumed during empty travel cycle of movable jaw plate, and the saved energy will be used in another travel cycle which makes the work load of machine become even. Pulley also plays flywheel role. Flywheel is always made of cast iron or cast steel, small size flywheel is normally as an integral type as fabricated. Please note flywheel static balance during its fabrication and installation.

6). Lubrication device eccentric shaft bearing

Normally concentrated circulation lubrication is applied; the feeding of oil to the supporting face of mandrel and push plate is normally by manually operated oil gun which feeds lubrication grease. The swinging angle of movable jaw plate is very narrow which makes difficulties in lubricating between mandrel and bush. So normally open some oil groove in axial direction at bottom of bush, and open a circumferential oil groove in the middle to make the lubrication way through. Then forcefully inject dry grease in with oil pump to make lubrication.

In recent years, many manufacturers want to substantially increase the quantity, reduce coal consumption through the transformation of rotary dryer. But the reforming effect of some manufacturers is not ideal, or even emerging the situation of the cylinder liner wear quickly, the under barrel and the head of the rotary dryer easy to burn out and the bag type dust collector using a shorter life, and the repairing cost is high and seriously affecting the normal production of the dryer.

It is not the reason of technical reformation problem, the effect of some technical transformation is very good, such as the installation of X shape lifting plate. Now many equipment manufacturers have adopted this technique, the main reason of effecting the effect is that the main emphasis on the dryer is transformed locality instead of modifying the dryer from the whole drying supporting system. The announcements in modifying the rotary dryer are as follows:

1. The selection of entilation dust removal equipment:

The ventilation effect of the dryer directly influences the yield level of production. If you want to have a high yield, you must select the dust collector of larger dealing capacity. Ensure the drying machine feeding end of certain negative pressure, timely absorb the high temperature gas generated by combustion furnace to to dryer and timely promote the heat exchange, as far as possible to reduce the concentration of the waste and achieve rapid drying purpose.

2. The inner transformation of the dryer:

The reconstruction investment of the rotary dryer is small and the transformation is relatively simple, but before the modifying you must understand the structure of the dryer, you can make a viable transforming measure according to the daily experience. General transformation steps:

(1) Install a center X type material-raising plates to reduce heat empty hole, prolong the remaining time of materials, improve the heat exchange efficiency and reduce the loss of high temperature gas.

(2) Remove the feed end of spiral conveyor leaf and replace by the triangular plate.

(3) Transform the feeding tube angle.

(4) Modify the L shaped tail lifting plate in the low temperature drying area.

3. Attention the balance between wind, fire, material:

The main base of gaining high quality and high yield is to achieve the ' wind, fire, material balance'. Firstly determine the dust ventilation, drying machine specifications, models and the effect of reconstruction, the combustion furnace heating size matching. Secondly we should strengthen the operation.
