How to select the right crusher blades?

When purchasing crusher blades, how should we choose the right one? Huaxin Blade recommends that you select the crusher blade according to the rotating speed of the host machine, feeding speed, feeding speed and screen aperture.

1. Engine speed

Generally, the spindle speed of hammer mill may be a fixed value, which is not adjusted at ordinary times, and can generally reach more than 6000 rpm. Due to high speed rotation, this bearing usually needs to be prepared with appropriate spare parts.

2. Feeding speed

The feeding speed will have a certain impact on the particle size of crushing. For materials that are good for crushing or whose particle size is not strictly controlled, the feeding speed may not have a significant impact. However, for some materials that are difficult to crush, it is necessary to strictly control the feeding speed. If the feeding speed is too fast, the particle size after crushing may not meet the requirements, such as controlling the particle size d0.9<15 μ M or so.

3. Feeding speed

In the design of domestic crusher blades, there may be design defects. Since the crusher will generate suction after it is opened, even if the feeding speed is very slow, the equipment can quickly draw materials directly into the crushing chamber, resulting in poor crushing effect. At this time, we need to manually control the feeding speed to improve the crushing effect.

4. Mesh size

The role of the screen is to filter out the materials that have reached the required particle size, leaving the coarse materials to continue to crush until the crushing is completed. From the brief introduction of the role of the screen, we can know that the aperture of the screen will have a great impact on our crushing effect.
