Hammer Crusher Application:
Hammer crusher is suitable for mid-hard and light erosive materials, whose pressure resistance strength is no more than 100Mpa and humidity lower than 15%, such as coal, salt, chalk, gypsum, blocks, limestone, etc.
Hammer Crusher Operating Principle:
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.
Single stage hammer crusher can crush the feeded materials of graininess1100mm into less than 20mm for one time, so the traditional double stage or three stage crushing can be changed into one stage crushing so as simplify the process can be simplified flow, and the equipment investment saved consumption and other production expenses reduced. The hammer crusher falls into reversible and non-reversible hammer crushers. Reversible hammer crusher with reversible rotor used for fine crushing in general; non-reversible hammer crusher with non-reversible rotor used for intermediate crushing. Single stage hammer crusher is non-reversible. Ordinary hammer crusher is composed of frame, rotor, grate bar, impact plate and adjustment unit; single hammer crusher is composed of frame, rotor ,feeding roll, grate bar, hydraulic opening unit and foundation.
