Pin mill is a pulveriser where the size reduction of particle takes place more due to the predominant shearing action on the product surface along with hammering action. Compared to conventional pulverizers the fines generated in this machine are much lower. A fine mesh output can be obtained when the product is agglomerate. Generally this machine also finds application where natural granular crystal structure is required while pulverising. Ideal application is Salt. The particle size control is due to the perforated sieve attached at the periphery of the machine. Heat generated in this machine is low. This machine is generally not suited for fibrous application.
