The Features and Application of Hammer Crusher

With the continuous development of science and technology, the crusher industry is changing quickly. Now the hammer crusher is widely applied to crush materials below medium hardness like limestone, slag, coal slag, coke, etc in cement, chemical, electricity, metallurgy and many other industries.

In order to keep the hammer crusher under normal functioning, we should have a good knowledge of its structure, the hammerhead and rotor designing principle and working principle. Here let's talk about the basic structure of hammer crusher: the hammer frame is installed on main bearing, and the hammer is hung between hammer frames. The shape and size of hammerhead is determined by the actual specifications of crusher and its feeding size. The hammerhead's swinging range on hammer frame is within 120. In order to protect the equipment shell from being destroyed by hammerhead and materials, we install a lining board in crushing chamber and install a grate in the under part of equipment.

Hammer crusher has a big reduction ratio, generally 10-25, and some will reach 50, which is an outstanding feature of crusher. In addition, hammer crusher has features like simple structure, compact model design, small covering area, light weight, convenient operation and maintenance, etc. As for the discharging granularity, the final products have even shape, little over crushing phenomenon and high fineness. It can satisfy the high-level production requirement and consumes less energy under the same condition.

The hammerhead and grate are easy to break, so they need to be replaced at fixed time. If the raw materials has high moisture content or contains clay soil, the grate is easy to be jammed, which causes the production capability reduction and stacking in crushing chamber.

Hongxing hammer crusher is easy to maintain, and we only need to put rod into the ring to open the latter part of the chamber.
