Size reduction of material using ball mill

BACKGROUND The ball mill works on the principle of impact between the rapidly moving balls and the materials Both the balls and the sample are enclosed in a hollow cylinder At low speeds the ball rolled over each other and attrition takes place 1 2 At critical speed the centrifugal force just occurs as a result the balls are picked up by the mill wall and carried nearly the top where that...

Rod/Ball Mill Eriez Lab Equipment

Ball/Rod mill Literature The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level They are the most effective laboratory mills for batch-wise rapid grinding of medium-hard to very hard samples down to finest particle sizes...

Ball mill is a metal cylinder which rotates about its horizontal axis The coarse sugar charged along with the metal balls breaks to fine powder by impact of metal balls The size reduction is actually to make the too large to be used solid materials usable...

Praticle Size Reduction in the Ball Mill Drug

The size distribution produced by the ball milling of various crystalline and non-crystalline materials showed that initially there was a fairly even distribution over the size range up to 355μm However as milling proceeded two distribution modes developed one at about 90μm the persistent mode and one at about 250μm the transitory mode...
