Pilot Impact Mill consists of the following main parts. viz; an auto feed mechanism, a grinding chamber, a set of hammers, a whizzer classifier, a cyclone with a blower and a set of cotton balloons. Raw material is fed by an auto feed mechanism to a grinding chamber lined by specially treated steel liners. There is a set of precisely balanced fast rotating swing hammers which accelerates the material on the liner. By the impact the material is broken into fine particles. From the grinding chamber the ground material is fed automatically to a whizzer classifier where the material is separated as fine and coarse. The fine material is sucked by a cyclone system and is delivered for bagging. The coarse material returns to the grinding chamber for further grinding. The cyclone system avoids any pollution. The beaters are reversible and can be easily replaced if need be.  The use of whizzer classifier eliminates the use of screens and hence their replacements. Particle size is determined by the setting of whizzer classifier. Impact Pulveriser model no IP-12 and IP-15 do not have feed control device and second stage group filter bags but only feed hopper.
