Impact crushers are versatile crushing machines that can be used in any stage of the crushing process. However, the features and capabilities of different impact crusher types vary considerably. Impact crushers are traditionally classified to two main types: horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers.

Reduce the effect of wear, lower impact crushing operating costs with the FL Strike-Bar™ Crusher. With 2,600 tph throughput capacity, it crushes material larger than 2 metres and 4 tonnes in a single rotor operation, combining advanced technologies with 50 years' experience in crushing for cement production.

An impact crusher is a crushing machine that uses impact energy to crush materials. The rotor rotates high speed when the machine is working, driven by the motor. When the material enters the blow bar area, it collides with the blow bar on the rotor and breaks, then is thrown to the impact device to be crushed again, and then bounces off the ...

laboratory type hammer crusher Disc Mills: Disc mills consist of two counter-rotating discs with ridges or teeth that crush the mineral samples by shearing and grinding actions. They are suitable for processing a wide range of materials, from soft to hard, and produce a fine output size ideal for analysis.

The phenomena can be studied with the pendulum impact test apparatus. Crusher productivity in quantities of a fixed size distribution is a function of power drawn as opposed to physical machine size. From the results of the pendulum tests, it is possible to visualize a small machine drawing more power outproducing a larger machine drawing less ...

Primary crushing operations takes boulder size feeds (20 to 100 inches) and reduces the material to secondary crusher feed size (1 to 20 inches) or mill feed size (0.5 to 3 inches). This video illustrates single- and double-toggle jaw crushers.
