A ball mill is a type of grinder or mill used to mill the materials into fine powder in pharmaceutical, chemical, or metallurgical industries. Ball milling relies on the impact and attrition between the balls impacting the material to be ground and the grinding media. Construction: 1.
Ball Bearing Types and Components
Y-bearings are ball bearings with an extra-long inner race that extends like a short pipe out of both sides of the bearing. These extensions provide two screw holes to fasten set screws into corresponding screw holes on the shaft. If two sticks were poked through the bearing's screw holes until they touched, they would form a 120-degree …
Ball And Race Mills
Ball And Race Mills In this mill the coal passes between the rotating elements again and again until it has been pulverized to desired degree of fineness. The coal is crushed between two moving surfaces, namely, balls and races. The upper stationary race and lower rotating race driven by a worm and gear hold the balls between them.

A mathematical model was developed for a ball-and-race mill based on specific rates of breakage and primary fragment distributions. ... It was demonstrated that the normalized primary fragment distribution produced in a pilot-scale Babcock E-type mill of 17 in. race diameter was the same as in the Hardgrove laboratory test mill and that …
Construction and Working of Ball Mill
Hardinge mill: In this type of ball mill the cylinder has a conical end towards a discharge point, In this mill, the larger balls remain inside the cylinder and the smaller balls are placed in the conical portion. As a result, coarser grinding occurs in the cylinder portion and a finer grinding takes place at the apex of the conical part.
