Technical principle of impact crusher

The impact crusher is a machine that utilizes the high-speed impact of the plate hammer and the rebound action of the counter-attack plate to cause the material to be broken by repeated impact. The hammer is fixed on the high-speed rotating rotor, and several counter-attack plates are arranged at different angles along the crushing chamber.

When the material enters the action zone of the hammer, it is firstly crushed by the first impact of the hammer, and at the same time, the kinetic energy is obtained, and the counterattack is rushed at a high speed. After the material collides with the counterattack plate and is broken again, it is bounced back to the action area of ​​the hammer and is again impacted by the hammer. This is repeated until it is broken into the desired particle size and discharged out of the machine. Compared with the hammer crusher, the impact crusher has a larger crushing ratio and can more fully utilize the high-speed impact energy of the entire rotor. However, due to the extremely easy wear of the hammer, it is also limited in the application of hard material crushing. It is usually used for coarse crushing, medium crushing or fine crushing of limestone, coal, calcium carbide, quartz, dolomite, iron sulfide ore, gypsum and chemical raw materials. Brittle materials below medium hardness. Shanghai Jingxiang Heavy Industry Machinery Co., Ltd. has a long history of designing and manufacturing heavy hammer crushers with advanced product structure, reliable performance, stable operation and low energy consumption.

This series of products is suitable for crushing various medium hardness and brittle materials, such as limestone, coal, salt, white Asia, gypsum, alum, brick, tile, coal gangue and so on. The compressive strength of the crushed material does not exceed 150 MPa. The machine is mainly used in cement, coal preparation, power generation, building materials and compound fertilizer industries. It can crush raw materials of different sizes into uniform particles, which is beneficial to the next process, reliable mechanical structure, high production efficiency and good applicability.
