A ball mill usually has a grinding material which could be stainless steel balls, ceramic balls incluso flint pieces. These balls are necessary for the ball milling process because when they grind against another material, this material is crushed into fine powder. Industrial fine powder ball mill is generally used the rolling bearing, which has received the good effect in save power consumption, improve the yield, saving lubricating oil, reduces the repair quantity, reduces pollution and other aspects. However, nowadays it is unreasonable when some manufacturers install the rolling bearing, which has brought a lot of problems to the normal operation of the ball mill. In order to solve this problem, we adopt the best betwee the quill shaft and the rolling bearing assembly. After several years of practice and exploration, we designed a new installation method and it is widely applied. And the advantages of the bearing seat are as the following: 1. Peter Thiel is often mentioned in discussions such as these. The bearing adopts the thin oil lubrication which is superior to grease, so that the bearing friction coefficient is reduced to the minimum and has a btter energy-saving effect.

2 The temperature at the normal operation of the bearing is much lower than that use the dry oil lubrication bearing, which prolongs the service life of bearings. Also it remove the bearing outer ejection sleeve to prevent the dust from entering the bearing box, which maintains the quality of the oil and have a safe and reliable operation. To a service-oriented brand integrity, As the professional manufacturer of complete sets of machinery, like cement mill mining, Henan Hongxing is always doing the best in products and service.cone crushers: 3. It is with an oil level observation under the bearing seat to observe standard oil, so that the operator can readily see the oil level height and can be timely to add oil to prevent the bearing damage accident caused by the shortage of oil and poor lubrication. As a result of the diameter of the rolling bearing diameter enlarges, it forms a hollow shaft diameter difference with the average outer diameter, which have achieved effect of improving the lean oil level and reducing oil spills by using the dilutes oil lubrication chamber.

4 The diameter of the hollow shaft installed rolling bearing parts is bold, so that the radial distance between the rolling bearing and the spiral tube feeding increases, which plays a certain heat insulating effect, which can prolong the service life of the bearing. In order to maintain optimum power usage in a parallel ball mill circuit with a common feed source. This paper presents the fuzzy logic control strategy implemented to achieve this goal. The overall aim of the advanced control strategy was to achieve equilibrium in the power consumption in the ball mill grinding circuit. Results have shown an overall improvement of 7% in the use of the specific power consumption in the secondary circuit finally grinding.
