Ring-Roll and Ball-Race Mills A ball or roller between two races or rings provides the grinding surfaces on which pulverization occurs. One or both of the races may rotate against a ball or roll (in a Ring-Roll Mill the rolls may rotate while the ring is stationary). Ring-Roll (Bowl-Mill) and Ball-Race Mills comprise the majority of coal
Jul 07, 2017· In ball and race mill the coal passes between the rotating elements again and again until it is pulverized to the desired degree of fineness. The coal is crushed between two moving surfaces namely balls and races. A worm and gear drove the upper stationary race, and the lower rotating race holds the balls between them.

From our original E/EL ball-and-race type pulverizers for lower capacity applications, to the latest B&W Roll Wheel™ pulverizer capable of grinding up to 230,000 pounds of coal per hour (104,300 kg/hr), we set the standard for high availability, reliability and low maintenance.
A particularly common kind of rolling-element bearing is the ball bearing. The bearing has inner and outer races between which balls roll. Each race features a groove usually shaped so the ball fits slightly loose. Thus, in principle, the ball contacts each race across a very narrow area.
This is the total clearance inside a bearing in the radial direction. Its numerical value can be calculated by subtracting from the diameter of the outer race roller path or ball groove I.D. two times the rolling element diameter and the O.D. size of the inner race roller path or ball groove.

groove ball bearings are the most common type of bear-ing, and can handle both radial and thrust loads. Due to their low-frictional torque, they are suitable for high speeds. In a ball bearing, the load is transmitted from the outer race to the ball and from the ball to the inner race. Since the ball is a sphere, it only contacts the inner and
