Structure of Grid Ball Mill. Grid type ball mill is mainly composed of feeding device,main bearing,liner,cylinder,manhole,discharge grid plates,end cover plate,big gear,coupling,gearing etc. Advantages of Grid Ball Mill. 1.Grid ball mill adopts antifriction bearing instead of sliding bearings,which reduces friction and save consumption.

These bearings are restricted to low loads, low-to-medium velocity and temperatures up to 100°C (210°F). Tilting-pad or pivoting-shoe bearings consist of a shaft rotating within a shell made up of curved pads. Each pad is able to pivot independently and align with the curvature of the shaft. A diagram of a tilt-pad bearing is presented in ...

one of the bearings stops the lateral motion. If the degree of roller misalignment is high, the pressure on this thrust mechanism (either a bearing end cap or a thrust collar) becomes high and increased bearing temperature results. The reaction to the axial motion of the support roller is kiln movement in the opposite direction.

(2) Sliding track bearings used in ball mills usually have strong cooling devices because of their large load. If the cooling device fails, such as blockage, the cooling effect will be poor, and the bearing temperature may also rise.

Effect of Balls Hardness on Rate of Grinding Tests by Coghill and Devaney show that the hardness of the balls has some effect upon the rate of grinding in mill. These results are plotted in Fig. 6.8a and it is seen that, both for dolomite and chert, there is an increase in the rate of grinding with increasing hardness of ball.
