Impact Crusher Hammer Shape

Plate hammer is the most important part in the impact crusher. In the crushing operation, the material is crushed by the action of the plate hammer. The material is crushed by the high-speed impact of the hammers. And the material is thrown to the impact plate above the rotor for crushing again. And then bounce back to the plate hammer operation area from the impact liner for re-crushing. Because the plate hammer and the material is directly around the relationship. Therefore, the material, shape and fixing method of the plate hammer all play a vital role in the crushing effect. The following is an introduction to the shape of impact crusher hammers and the way of fixing.

1. Shape of plate hammer

Straight line hammer: the material collides in the direction of the hammer, and the impact force is stronger. Therefore, the crushing effect is good.
Lunar hammer: sturdy and durable. Long service life

2. The plate hammer needs to be installed on the rotor in the impact crushing. There are several ways to fix the plate hammer:

1) Fixing by bolts. Insert the plate hammer from the rotor side shaft into the corresponding slot hole of the rotor. It prevents the shaft from tampering and displacement. The two sections are then positioned using a pressure plate. Thus increasing the reliability of the plate hammer. Then use the centrifugal force and impact force generated in the continuous rotation of the plate hammer. The counterforce generated in the process to achieve self-locking. The parts of the rotor that wear each other can be made into a replacement structure. Easy to disassemble. Simple structure.

(2) Pressure plate fixing. The hammer is inserted into the groove of the rotor from the side. Both ends then use the pressure plate to press. This installation method can make the plate hammer appear not strong enough. In the process of high-speed operation, it is easy to loosen the phenomenon. This kind of fixing method for the plate hammer production process requirements are quite high. And need to be made of high manganese steel and other alloy materials.

(3) Wedge anchoring, the use of wedges to fix the impact crusher plate hammer and rotor. In the process of operation. Under the action of centrifugal force. The faster the rotor speed. The more firmly the plate hammer is fixed. And it works reliably. It is also relatively easy to disassemble and replace. It is also the most used certain fixing method at present. The wedge is usually made of cast steel material with certain ductility. It has high hardness and strength.
