Crushers generally deal with larger pieces of material, the product size is coarser, usually greater than 8 mm. Its structural feature is that there is a certain gap between the fragments and they do not contact each other. Crusher can also be divided into crusher, medium crusher and fine crusher. Generally speaking, the material treated by the grinder is finer, and the product size is fine, up to 0. 074 mm, even thinner. Its structural characteristics are that the crushing parts (or media) contact each other, and the medium used is steel ball, steel bar, gravel or ore block, etc. But some machines have both crushing and grinding functions, such as self-grinding machine. _5. 5 x 1. The maximum particle size of ore treated by 8-meter self-grinding machine can reach 350-400 mm, and the fineness of the product can reach - 200 mesh, accounting for about 40%.
Then what factors influence the crushing capacity of crusher?
1: Hardness of raw materials. If the hardness is high, it is difficult to break up.
2: Moisture-regulating material, that is, if the material contains higher water, it is easy to attach to the crusher, and easy to insert when the material is transported in the process.
3: Output size. When the output size is small, the capacity is low.
4: Composition of materials. If it is in the powder of the raw material, it may reduce the capacity. Because the powder will stick easily. The powder content should be screened before comminution.
5: Viscosity of materials. That is, higher viscosity, it is easier to adhere.
6: Quality of vulnerable parts (such as hammer, jaw plate). If there are any good shortcomings in the fast wear area, it will reduce the downlink capacity.
