Impact Crusher - an overview ScienceDirect Topics

Impact crushers (e.g., hammer mills and impact mills) employ sharp blows applied at high speed to free-falling rocks where comminution is by impact rather than compression. The moving parts are “beaters,” which transfer some of their kinetic energy to the ore particles upon contact. Internal stresses created in the particles are often large enough to cause them to shatter. These forces are increased by causing the particles to impact

01/04/2019  A key influence on the comminution process in the impact crusher is the rotor speed. Fig. 2 shows various product curves for limestone as a function of the rotor speed in the primary crushing stage. A higher rotor speed generally produces a finer product. So for a limestone feed in the size range 50 – 1000 mm at a rotor speed of 25 m/s, a product size P80 ≤ approx. 70 mm can be expected ...

Crusher - Wikipedia

Mineral sizers are a variety of roll crushers which use two rotors with large teeth, on small diameter shafts, driven at a low speed by a direct high torque drive system. This design produces three major principles which all interact when breaking materials using sizer technology. The unique principles are the three-stage breaking action, the rotating screen effect, and the deep scroll tooth pattern.

Crushers - QueensMineDesignWiki

The double roll crushers have two high-speed, parallel, toothed rollers with a fixed gap between them. As the material passes through them, it is subjected to mostly compression forces and some impacting forces. The low speed sizer is equipped with two toothed rolls. Even though the two rolls revolve slowly in an enclosed chamber, they have a high torque. These teeth are placed in an arrangement such that

Vertical shaft impact crushers take the full advantage of so-called rock-on-rock crushing process. In vertical shaft impact crushers, the crushable material is fed through the centre of the rotor, where it is accelerated to high speed before being discharged through openings in the rotor periphery. The material is crushed as it hits of the outer body at high speed and due to rocks colliding against each other. Vertical shaft impact crushers
