feeding (e.g., making metering into the mill difficult), grind-ing (e.g., plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (e.g., plugging the bag filters). There are two ways to grind sticky materials. The first solution is to dry the material prior to grinding, or dry and
designed to slow both air and product in the mill. This improves grinding performance and prolongs hammer and screen life. Bliss mounts the rotor between the bearings. No overhung rotor. Still because of the Eliminators superior design, the rotor can be removed from the side, without removing the upper mill housing and feeder system.
The robust, industrial hammer mills type HM 142, HM 342 and HM 672 are used for crushing materials ranging from dry to damp, soft to tough, chewy to brittle. Depending on product characteristics and the desired milling result, both types may be equipped with a variety of sieve and bar grate screen inserts.
The effect of mill parameters, namely, the screen aperture size, and impeller speed on the particle size distribution of the milled product was quantified for a conical screen mill and a hammer mill. In general, the conical screen mill was found to be more sensitive to changes in impeller speed compared to the hammer mill.

Meanwhile, the losses were (7.25%, 6.40% and 6.29%) respectively. The difference between results was due to the mechanical ...
Hammer Mill. The hammer mill is an impact mill employing a high speed rotating disc, to which are fixed a number of hammer bars which are swung outwards by centrifugal force. Material is fed in, either at the top or at the Centre, and it is thrown out centrifugally and crushed by being beaten between the hammer bars, or against breaker plates fixed around the periphery of the
