Description

1.Hammer Crusher Usage and Application Hammer crusher is applicable for various hard and fragile materials, such as barite, coal, salt, chalk, gypsum, blocks, limestone, silica sandstone etc and mainly used in such industries as cement, coal separation, electricity generation, building materials and compound fertilizer, etc. The hammer crusher can crush materials with different sizes into equal particle, which favors the next procedure. Hammer crusher is suitable for both dry and wet crush of brittle, medium-hard materials for the mining, coal, construction material, road building, and chemical industries. The crushing compressive strength of materials should not be in excess of **0Mpa. 2.Hammer Crusher Working Principle and Features 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 smaller size than the screen mesh will be screened out and others are left to be further ground until reaching 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.
