Product Introduction
Coal Crusher is suitable for crushing various brittle materials, such as coal, gangue, coke, slay, shale and loose lime stone etc. Its compressive resistance no exceeds 100Mpa and the surface moisture content should not be greater than 15%. The PC hammer crusher crushes by the collisions between high-speed hammer and material, which features in its simple structure, high reduction ration, high efficiency, ect.. The PC hammer crushers were developed for the both dry and wet crushing of brittle, medium-hard materials for the mining, cement, coal, metallurgic, construction material, road building, and Petroleum & Chemical industries.
Operating Principle
When materials get into crusher, first they are broken by the impact of ring hammer with high-speed rotation of the rotor. At the same time, the broken materials get power from ring hammer, and crush toward broken plate, being broken for the second fragmentation. Then they fall on the sieve plate, where they are further broken because of shear, extrusion, grind by ring hammer and interaction between materials. At last, they are discharged through the sieve pores. Sundries that can't be broken are put into metal collector and periodically removed.
Main Characteristics
1. The space between grid sections can be adjusted to change discharging granularity in line with clients' needs.
2. It is highly efficient and energy saving, and causes low noise and little dust.
3. Simple structure design, large crushing ratio and high production efficiency.
