According to kefid more than 20 years of experience, the factors that impact the productivity of crushing machine are including internal factors and external factors. Internal fragmentation is the features of the machinery itself, the external is the influence of the materials nature.

1, the hardness of the material. The harder the material,  the more difficult to crush up, and the more serious wear and tear on the equipment. So it has a slow crushing speed and low crushing capacity.
2, the humidity of materials. If contain more water, materials are easy adhere to the crushers, and easy to block the discharge hole, resulting in the crushing capacity decreases.
3. the fine degree of final products.
More fine final products need more crushing process course, it will increase the material crushing times, the crushing capacity become smaller.
4, the material of the crusher. If the crushing parts of the crusher have good abrasive resistance and great crushing ability, it will increase the crushing capacity.
