Sand making machine is a kind of crushing equipment, and it is also a special equipment for sand making industry. The produced materials have the characteristics of uniform and excellent particles. During the long-term use of the equipment, the sand production rate will gradually decrease. So, what is the specific reason? In this paper, we briefly summarized several points.

1, the wrong production mode has certain influence on the sand production rate of the equipment. There are two modes of production, namely, dry method and wet method. Among them, the wet production mode is inefficient, and materials need to be aired and sprayed for dust prevention in the production process. Therefore, the material has high water content and high viscosity, which causes the hammer of equipment parts to get stuck, and the crushing effect is not good. The broken material is easy to get stuck in the crushing cavity, which leads to the broken material not being discharged in time, blocking the equipment and affecting the sand production rate.

2. The sand production rate of dry production method is higher, which is more serious than wet dust pollution, but it does not exceed the national environmental pollution index. Because of its special structure, the sand maker can form internal circulating airflow in the crushing cavity, which reduces dust pollution.

3. When the sand-making rate of the sand-making machine is low, the reason is that the main crushing parts are seriously worn, and they can't reach the moving state when they leave the factory, which affects the sand-making rate of the equipment. Among them, the broken parts of the equipment include rotor, throwing head, hammer head, spindle and other parts, especially rotor. When the rotor spindle is bent or seriously worn, the rotor loses its balance. If it is not maintained in time, it will affect the sand production rate of the equipment.

4. The size and hardness of the material will also affect the sand making rate of the sand making machine. When the material is too large to be broken in time, it will form a blocking phenomenon, thus reducing the sand production rate. At the same time, the harder the material is, the slower the crushing speed is, the lower the quality is, and the equipment is seriously worn. It is recommended not to exceed the range specified by the equipment itself.
