Three methods of impact crusher crushing materials

The impact crusher adopts the principle of impact to achieve selective crushing of materials when working. Its product has good grain shape and few needles and flakes. It is often used for the final crushing of roadbeds and roads with high aggregate requirements.It can also be used in fine crushing operations in building materials, mining and metallurgical industries. When working, the impact crusher has the following processes to crush materials:

1. Free crushing in the crushing cavity

The ore entering the crushing cavity will quickly receive the impact of the hammer on the high-speed rotating rotor. In addition, it will also be subject to the interaction between the materials. These forces make the materials in the crushing cavity crushed.

2. Rebound broken

The crushed materials are not scattered indefinitely, but are all contained in a box-shaped frame. Due to the action of the hammer on the high-speed rotating rotor, the material gains a high moving speed, and then hits the frame.The frame body acts on the material with the same magnitude and opposite direction to make the material further broken. This kind of crushing effect is also called "rebound crushing".

3. Shearing and breaking

Shearing crushing is the material larger than the size of the discharge opening that has not been broken by free crushing and rebound crushing, and it is sheared and broken by a high-speed rotating hammer at the discharge opening.

Among the three crushing methods, the free crushing and rebound crushing of the material in the crushing cavity indicate that the hammer head impacts the material in the working principle of the impact crusher and the material that has obtained huge kinetic energy is further impacted by the impact plate and the material. Shearing crushing is not a specific form of selective crushing of materials by an impact crusher, but a product of specific structural forms.
