Overview
Secondary Impact Crusher is widely used in construction material, highway and railway, cement, mining and chemical fields etc. It is designed to crush soft and medium hard rock. The size range of feed material (maximum compression strength 300Mpa, the moisture should be below 8-10%) can be up to 700mm. Hydraulic impact crusher improves the adjusting device making operation more convenient. The three– cavity makes excellent capability in fine crushing and super fine crushing line.
APPLICATIONS
Railway, road construcion, other industries.
Features
1. Hammer is made of high chrome;
2. Liner board is made of wearable materials;
3. Specially designed tooth impact plate;
4. Excellent cubical final product and high ratio of reduction.
Working Principle
Secondary Impact Crusher is a kind of crusher which crush the raw material by using impact energy. When enter the zone of the board hammer, the raw material is crushed by the high-speed impact of it. And then the raw material is threw up to the impact device installed on the rotor and is crushed again. Then the raw material is crushed for another time when it is rebounded from impact liner to the zone of board hammer. The process repeats until the raw material is crushed into the desired size and discharges from the bottom of the machine. The final product size and shape can be changed by adjusting the gap between impact frame and rotor frame. European Type Impact Crusher adopts spring safety device behind the impact liner. When the non-crushed items enter the crusher chamber, the impact frame front and back will be draw back and the non-crushed items will be discharged from machine.
