Comminution features in an impact hammer mill

Impact hammer mill produces self-similar distribution of product with a high reduction ratio. Median size of product is exponentially related to the quantity of fines generated. Reduction ratio and specific energy are linearly related. The quantity of fines generated in the mill is an indirect measure of the mill wear.

What is Hammer Mill? Working Principle

Hammer mill works on the principle of impact for size reduction of materials. Impact is offered to the feed by the sets of swing hammers which are arranged on a rotor disk. Construction of Hammer Mill. It consists of a casing in which a horizontal shaft is present (see Figure 1). A high speed rotor disk is attached to this horizontal shaft.

Understanding the Working Principle of Hammer Mills

The hammer mill working principle involves uniform size reduction of aggregate raw material achieved by repeated blows with hammers on a rotating shaft. (877) 247-5625 ... For example, the higher RPMs of a rotor will increase the centrifugal force of the hammers, which magnifies the impact force of each blow upon the material. The RPMs …
