Hammer crusher crushes the material by the collisions between the materials and high-speed rotating hammer body. It has the advantages of simple structure, big crushing ratio, and high production efficiency and so on. Hammer crusher can adopts dry and wet crushing way. The Compressive strength of material does not exceed 100 MPa, moisture content is less than 15%. The broken material is coal, salt, chalk, plaster, brick and tile, limestone, etc. Hammer crusher, moreover, not only can be used for crushing production line, sand making production line, but also be used in mineral processing production line instead of cone crusher. There are many hammer crusher manufacturers in the mining market; the customer should have a careful comparison on the enterprise strength and manufacturing experience.
1. Big reduction ratio: maximum feeding size is 1.3-1.5m; 3-150mm of discharging size.
2. High fineness of discharged particles: favorable shape with aggregate, the powdery material is no more than 20%.
3. Simple production process: the two or three stage crushing is reduced into single stage.
4. Economical: small capacity of matched motor, which greatly reduces the production cost.
Hammer crusher can be divided in to single-stage hammer crusher, high-efficiency hammer crusher, sanding machine, vertical-shaft hammer crusher, reversible hammer crusher and ring hammer crusher. Changing the hammers of this machine into ring coal crusher with steel ring will make a new hammer crusher. It is mainly used for crushing coal in the power plant, and it can also be used for crushing gypsum, salt and other chemical raw materials and some other medium hard materials. In addition, it can not only used in crushing production line and sand making production line, but in the ore beneficiation production line replacing cone crusher.
The electromotor drives the rotor to rotate with high speed in the crushing chamber. The materials are fed into the machine from the upper feeding mouth and are crushed under the hitting, impacting, cutting and grinding of the hammer which is moving with high speed. On the bottom of the rotor, there is sieve plate and the crushed materials that is smaller than the screen size are discharged from the sieve plate, and the coarse particles bigger than the screen size are retained on the sieve plate to be hit and ground again by the hammer and finally be discharged from the machine from the sieve plate.
