The crushing equipment-hammer crusher

Hammer crushers are the equipment directly crushing the materials whose maximum particle size is between 600 and 1800mm to below 25 or 25 mm. Hammer crushers are applied in cement, chemicals, power, metallurgy and other industrials to crush the medium-hard materials, such as limestone, slag, coke, coal etc for the intermediate and fine grinding operations.

Hammer crushers’ working principle: hammer crushers mainly finish material crushing operation by the impact energy. When the hammer crusher works, the motor drives the rotor to do high-speed rotation, materials are uniformly into the crusher cavity, high-speed rotary hammer impact, cut and tear the materials until the materials are broken. At the same time, due to its own gravity, the materials rush to the bezel, strips on the frame plate from the high-speed rotary hammer. The materials whose size is greater than the mesh size are left on the screen plate to be grinded and impacted by the hammer. Finally it is out of the machine from the screen plate when crushed to the required particle size.

According to the number of rotor, hammer crusher could be divided into two sorts: single-rotor hammer crusher, double-rotor hammer crusher. They mainly include the following components: hammer, rotor, grate, grate bars and breaking plate, the machine shell, safety devices, the transmission system. Due to the advantages of large capacity, large crushing ratio, low power consumption per unit of product, simple and compact structure, lightweight, easy to be operated and maintained, they are widely applied in production.

The hammer crushers produced by Zhengzhou mining machinery Co., Ltd inherit 50 years of technical advantage with continuous improvement and innovation, not only having low power consumption, but also high quality, which is the ideal equipment for intermediate and fine grinding.
