The main part of hammer crusher is rotor. Rotor consists of main shaft, disc, pin roll and hammer. Motor drives rotor to rotate at a high speed. Materials are fed into crusher and crushed by the rotor. There is a screen deck at the bottom of rotor, the products that reach the target may discharged through screen deck, and the coarse particles may stay on the deck for crushing until reach the target.
Hammer crusher is widely used for medium and fine crushing in mineral processing, cement, glass and refractory factories. It can be used in both dry and wet crushing.
The feed material is crushed by means of rotating beaters with reversible heads by impact against the grinding walls. Due to reversible rotor with crushing ledges arranged on both sides, the wearing faces of the hammer heads can be completely used without reversing the hammers.
A grate can be fitted, if necessary, at the outlet to obtain required product gradations. These crushers are best suited for limestone, ore with low Iron content, gypsum, etc.
