Crusher blade selection skills

1. Main engine speed

Generally, the spindle speed of a hammer crusher may be a number, and it is usually not adjusted, which can generally reach above 6000rpm. Due to high-speed operation, this rolling bearing generally requires appropriate accessories.

2. Feeding rate

The feeding rate will have a certain impact on the particle size distribution of crushing. For materials that are well crushed, or raw materials whose particle size control is not very strict, the feeding rate may affect it is not too obvious. However, for some materials that are difficult to crush, it is necessary to strictly control the feeding rate. If the feeding rate is too fast, the particle size after crushing may not meet the requirements, such as the control particle size d0.9<15μm.

3. Feeding rate

When the domestic crusher blade is designed, it is very likely that the design is defective, because the crusher will also generate adsorption force after opening, even if the feeding rate is relatively slow, the machine equipment can quickly suck the raw materials into the crushing cavity immediately, resulting in the actual effect of crushing. decline. At this time, we need to manipulate the feeding rate by human factors to improve the actual effect of crushing.

4. Screen aperture

The function of the mesh screen is to filter out the raw materials whose particle size distribution has reached the requirements, and leave the coarser raw materials to be crushed again until the crushing is carried out. According to the introduction of the function of this screen, we can understand that the diameter of the screen will have a great influence on our crushing effect.
