At critical speed of rotation, ball mill rotates at . Discussion; Sravanthi -Posted on 07 Oct 15 The material to be disintegrated is tumbled in a container along with wear resistant solid balls in ball milling method.
A synchronous electric motor is an AC motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles.
This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge. Below describes in general terms the Bond Work Index Procedure used by .

The Ball Mill and Rod Mill Modules are used for fine grinding of solid matter by impact and friction, in wet or dry condition. The drum, which contains the sample and grinding balls or rods, rotates around a horizontal axis.
Grinding in ball mills is an important technological process applied to reduce the . The speed of rotation of the mill determines three basic types of operation modes: slow rotation (cascading), fast rotation (cataracting) and very fast rotation (centrifugation). Each type is characterized by a specific trajectory of motion of the
Ball mill is a horizontal rotating device transmitted by outside gear. Material is transferred to grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner with different specifications of steel balls in the chamber.
Classification liner for the second chamber of the ball mill Therefore, using small balls was known to be more efficient as this increases the surface area of media and improves the grinding effect.
