Factors Affecting The Crushing Effect Of Impact Crusher

Impact Crushers are widely used in engineering technology such as road construction, metallurgy, mining, building materials and transportation. It combines the principles of crushing, counterattack, centrifugal shock, shearing, grinding, etc. organically to make full use of energy and crushing cavities. It can break the hard material with compressive strength of 300MPa or more, and has the characteristics of large crushing ratio and good graininess. This makes the Impact Crusher occupy an important position in many crushing machines. The crushing effect of the Impact Crusher has a significant impact on the quality of the finished material. The main factors affecting the crushing effect of the Impact Crusher are as follows:

1, Rotor Rotation Speed

Studying the rotor rotation speed can guide the Impact Crusher to select the appropriate rotation speed when crushing materials of different particle sizes and materials, thereby preventing the material from being excessively broken, and also helping to reduce energy consumption. The higher the rotor speed, the greater the impact force when the hammer is in contact with the material. As the speed increases, the impact force of the material collides with the counterattack plate, the better the material impact crushing effect, the higher the damage degree of the material, so the hammer between the hammer and the material, the material and the counterattack plate occurs in the subsequent shear fracture. The interaction force is smaller.

2, Rotor Moment Of Inertia

Generally, the range of materials that can be broken by each type of Impact Crusher is certain, which is largely related to the rotor inertia of the type of crusher installed. When the rotor speed is the same, different rotations are required. The inertia of the rotor can provide different crushing forces, that is, the crushing capacity is different, directly affecting the performance of the crusher.

When the material is impact-broken, the greater the moment of inertia of the rotor at the same speed, the greater the impact of the hammer on the material and the material and the counter-attack. When the material is shear-crushed, the counter-attack is less affected by the material. The more easily shear fracture occurs.

3, The Angle Of The Counterattack Plate

The angle of the counterattack plate at each level has a great influence on the effective crushing force generated when the stone hits the counterattack plate. Usually, the force perpendicular to the interface of the collision contact is the effective crushing force, which is the force that can cause the rock to break. The most ideal situation It is that the stone can be perpendicular to the counterattack plate each time it collides with the counterattack plate, and the counterattack plates of different angles have a greater influence on the impact of material impact and shear fracture. Reducing the angle of the first-stage counter-attack plate has better effect on shearing and crushing of materials, but it is not conducive to impact crushing of materials; increasing the angle of the first-stage counter-attack plate can increase the number of impact collisions and enhance the effect of impact crushing, but it is not conducive to material shearing.
