Generally the driven mill sheave is of split hub construction to facilitate field assembly. V-belt drives allow use of higher speed motors, generally low in initial cost. Motor speeds should be between 580 and 1160 rpm. The lower speeds apply to large diameter mills, the higher speeds to the smaller. DIRECT CONNECTED Ball Mill DRIVE

The drive components are the mechanical components that "drive" the CNC machine along its axis. The most common components associated with a drive system, are the motors, lead or ball screw, or rack and pinions. The whole idea of a drive system is to convert controlled rotary motion to controlled linear motion with the help of a CNC Controller.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati
