Impact Crusher Working Principle. Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them. Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate …

The Powerscreen® Trakpactor 550's robust impact chamber features a twin apron, 4 bar rotor design, with hydraulic release aprons, hydraulic setting adjustment, hydraulic crusher overload & is driven directly off the engine via clutch for optimum fuel economy.

The simulations indicate that even at much lower speeds, the performance of a double impeller impact crusher is exceedingly superior. However, the energy associated with the double impeller impact crusher is much higher and energy intensification, rather than energy efficiency, is the main gain of the double impeller design.

Bwalya and Chimwani (12) compared the energy spectrum above the threshold energy in single-rotor and double-rotor impact crushers under different operating conditions. Moreover, the authors concluded that a double-rotor could increase the proportion of high energy, even at low speed, thus improving the breakage efficiency.

In double-shaft hammer crushers, the crushing of the feed material is mainly performed by the rotating hammers between the rotors and on the anvil.

The ® APS Series horizontal shaft impact crusher is renowned for its secondary crushing capabilities, without compromising the quality or size of the end product. These impact crushers feature a large unobstructed opening for slabby feed such as concrete and asphalt. They can also be used for aggregate crushing and recycling applications.
