Hammer Crusher is mainly used for crushing medium-hard or brittle materials with hardness not more than 300Mpa and 15% moisture such as barite, limestone, terrazzo, silica sand stone, coal, coke, gypsum, aluminum sulfate, slag, salt, chalk, blocks, cement, alumen, brick, tile, etc.

It has the features of simple structure, big crushing ratio, high production efficiency, uniform particle size, etc. The hammer crusher is one of the main equipment for intermediate and fine crushing the brittle materials with less than intermediate such as limestone coal and other used in metallurgy, building material, chemical and water - power industry, with a feature of big crushing ratio and even product graininess. And hammer crusher can crush materials with different sizes into equal particle, which favors the next procedure.

The PC hammer crusher(hammer mill) were developed for both dry and wet crushing of brittle, medium-hard materials for the mining, cement, coal, metallurgic, construction material, road building, and petroleum & chemical industries. This crusher machine can be also used for crushing chips and paper with fiber structure and strong elasticity and ductility, or recycling asbestos fiber by crushing wastes of asbestos cement, etc. Gap between the gratings are adjustable to change grain size of the discharge.

Working Principle of hammer crusher

The main working part of hammer crusher is rotors with hammer. The rotors consist of main shaft, disk, pin shaft and hammers. The motor drives the rotors to rotate quickly in the crushing cavity. Raw materials enter the crusher through the feed opening and are stricken, impacted, cut and ground by the high-speed hammer to small size. There is a screening plate under the rotor, so that materials with size smaller than the screen mesh will be screened out and others are left to be further hammered and ground until reach the standard size. The size of the final product can be adjusted by changing the screening plate. The gap between the rotors and the screening plate can also be adjusted according to different requirement.

Not only can the hammer crusher be applied in crushing production line and sand making production line, but it also replaces the cone crusher in beneficiation production line.
