Overview

PFW series impact crusher with the advanced world standard is latest generation product, absorbing the latest technology around the world. Because the rotor is the key part of the impact crusher and also the most critical part of inspection and acceptance, our company develop and produce the strong and heavy type rotor in order to get the higher rotary inertia. The use of high abrasion-resistant material and the best design of the crushing chamber make the performance of the crusher more remarkable. PFW series impact crusher improve the adjusting device, easy to operate. The design of three chamber crushing make the PFW series impact crusher perform well in the fine crushing and superfine crushing operation. The design of the two chamber crushing simplifies the flow chart of coarse crushing operation.

Features

• 1.World-class skills in making are adopted and the use of high-tech materials.
• 2.More advanced movable jaw assembly makes it more long-lasting
• 3.Use of finite element analysis technology makes the crusher with high intensity
• 4.More quickly and convenient adjustment at the discharging opening
• 5.European style PEW series of Jaw Crusher are equipped with wedge adjustment devices, which is simpler, safer and faster
• 6.Chosen bearings are larger with better carrying capacity
• 7.The newly-adopted tooth-boards have greatly increased the effective length of the jaw, resulting in larger yield
• 8.Integrated cast steel structured axle bearing housing can guarantee to be perfectly cooperating with the crushing frame. Meanwhile, it greatly increased the intensity of the axle bearing, which could not be performed in the separated style axle bearing.

Working Principle

European Type 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.
