Rod & Ball Mills. 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.
Wheel grinding mixer consists of a pair of rollers and a pair of shoveling plates. Charcoal particles are grinding into powder by the roller, and the carbon powder is blended with water and a binder evenly. It is ideal equipment for producing charcoal and coal rods, pressed pellets, honeycomb briquettes and etc.
