The market has a large demand on artificial sand so that the sand maker is widely paid attention. Strictly speaking, sand maker is one kind of crushing equipment. Because of its special crushing effect and particle size, it cannot be replaced by other crushing equipment. Board hammer is vital parts of crushing equipment, and its fastened ways in the rotor affect work efficiency of the device. Therefore, we must have a overall view of fastening board hammer of sand maker. There are three common ways to fasten board hammer.

1. Embedded Fastening Type: The board hammer is firstly inserted into the corresponding slots besides rotor, and then fastened by a pressure board. This method can operate easily, and the rotor has a less wear.

2. Bolt Fastening Type: As the name suggests is using bolt fastens board hammer on the rotor. The method can make the blot fastening firmly, but need a lot time in replacement.

The above is three methods of fastening board hammer of sand maker. We should the quality in choosing board hammer, and then shape.
