The blower is one of the most important parts of the impact crusher when processing materials. It directly contacts the material and crushes it. Therefore, the material and fixing method of the blower directly affect its production efficiency.

Material and type of hammer:

The hammer is generally made of high-chromium cast iron with strong wear resistance. The blowback hammers for counterattack have straight type and crescent type. The blow bars produced by Shuangjin are straight type, which has the advantages of large crushing force, high crushing efficiency, wear resistance and durability.

How to fix the board hammer:

Bolt fixing, pressure plate fixing, and module fixing are gradually improving. Module fixing is a more commonly used form of fixing at present. It is not easy to fall off, but also ensures that the faster the rotor speed, the stronger the hammer. And the work is reliable, and it is convenient to disassemble and replace. In addition, since the relative string movement between the blow bar and the rotor is eliminated, the wear of the rotor is reduced.
