Reasons affecting the performance of impact crusher

The impact crusher has a large crushing ratio and a simple structure, and is widely used in railways, building materials, highways, mining and other industries. In the sand production line, the impact crusher is also a kind of equipment that is widely used. Factors affecting the production efficiency of impact crusher:

1. Rotor speed

The rotor speed of the impact crusher is good. When the impact crusher crushes materials with different properties and particle sizes, choosing a reasonable rotation speed is not only conducive to reducing energy consumption, but also preventing excessive crushing of materials.

Generally speaking, the higher the rotor speed, the er the impact force between the blow bar and the material, the better the impact and crushing effect of the material, but the er the damage to the material.

2. Rotor inertia

The range of crushed materials of different types of impact crushers is determined, which is related to the moment of inertia of the rotor of the crusher. When the rotor speed is the same, the moment of inertia is different, and the crushing force provided by different types of crushers is also different, which will directly affect the crushing. crushing of the machine.

Generally speaking, the er the inertia moment of the rotor at the same speed, the er the impact and extrusion between the material and the blow bar or impact plate. After the material is sheared and broken, the smaller the reaction force of the reverse impact plate, the er the possibility of the material being cut and broken.

3. The angles of the counterattack boards at all levels

When the rock hits the impact plate, the angle of the impact plate will affect the crushing force generated by the impact of the rock. We usually refer to the force normal to the impact interface as the efficient crushing force, the force that can break the rock. So, in the good case, the rock hits the impact plate vertically.

These factors have an active guiding role in the design and production of the counter. As one of the commonly used crushers, it is necessary to pay attention to anti-breaking in the process of using the production line, which helps to improve the production efficiency of the production line.
