Mill Speed - an overview ScienceDirect Topics

In the ball-and-race mill (Fig. 13.3), balls are held between two races, much like a large ball bearing. The top race or grinding ring remains stationary while the bottom race rotates. As the coal is ground between large diameter balls and the ring, the balls are free to rotate on all axes and therefore remain spherical.

Rolling-element bearing - Wikipedia

In practice, the ball deforms (flattens) slightly where it contacts each race much as a tire flattens where it contacts the road. The race also yields slightly where each ball presses against it. Thus, the contact between ball and race is of finite size and has finite pressure. The deformed ball and race do not roll entirely smoothly because different parts of the ball are moving at different speeds as it rolls. Thus, there are opposing forces and sliding motions at each ball/race ...

The characteristics of the two mills are similar, although the material remains longer in the tube mill because of its greater length, and a finer product is therefore obtained.

outer races that increases load capacity relative to standard round rail guides. The ball track groove in profile rail guides is only slightly larger in radii than that of the balls themselves. The geometry cradles the balls as they infinitesimally flatten under load, slightly expanding the contact area between the balls and the races. As a result, profile-rail bearings are roughly 10 times stiffer than a traditional

01/01/2019  The mill has an advantage over the compound ball mill in that the large balls are raised to the greatest height and, therefore, are able to exert the maximum force on the feed. As the size of the material is reduced, smaller forces are needed to cause fracture, and it is, therefore, unnecessary to raise the smaller balls as high. The capacity of the Hardinge mill is higher than that of a ball mill of similar
