Ball mill  Wikipedia
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

Question: (a) From First Principles, Derive An Expression For The Critical Speed Of A Ball Mill With An Internal Diameter D, And Operating With Steel Balls Of Diameter D (5 Marks). (ii) Explain The Effects On The Grinding Performance Of A Ball Mill Of Operating The Grinding Mill At A Speed Above Or Below The Critical Speed (5 Marks).

Critical Velocity in Circular motion Vertical plane
Critical velocity in vertical circular motion – Definition. The minimum velocity of an object having circular motion in a vertical plane, at the highest point of the rotation is called Critical Velocity.. If the velocity falls below this at the highest point then the object will not be able to continue in its circular path.

Critical rotation speed for ballmilling 
To examine the dependence of critical rotation speed on ballcontaining fraction, we measured critical speeds at various ballcontaining fractions from 0.3 to 0.95 stepped by 0.05. Since at lower fraction than 0.3 we could not observe the centrifugal motion, we chose this fraction range. A jar of ballmill consists of a cylinder and two lids.

Ball Mill  an overview  ScienceDirect Topics
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
