Ball Mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard soft brittle fibrous temperature-sensitive and moist samples down to the finest particle size. The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding

High energy ball milling process for nanomaterial synthesis
· (a) At the initial stage of ball milling the powder particles are flattened by the compressive forces due to the collision of the balls. Micro-forging leads to changes in the shapes of individual particles or cluster of particles being impacted repeatedly by the milling balls with high kinetic energy.

Principle and Working of MILLING MACHINEEngineering
· Introduction Milling is the cutting operation that removes metal by feeding the work against a rotating cutter having single or multiple cutting edges. Flat or curved surfaces of many shapes can be machined by milling with good finish and accuracy. A milling machine may also be used for drilling slotting making a circular profile and gear cutting by having suitable attachments.
