Rotary crusher

drobilkaOur company manufactures modifications crushers rotary - rotary toothed crusher. In this crusher on the main operating member - rigidly fixed toothed rotor segments uniformly distributed over the entire surface of the rotor in a certain order. All toothed segments at the ends have soldering of high-strength alloy. That increases their resistance to wear and, accordingly, the service, and also allows you to work with high hardness materials. Size, number of toothed segments, frequency and the order of their location on the rotor can be pre-lay a fraction the size of the processed material crushing and, ultimately, the performance of the device. On the performance of the installed capacity of the engine is also affected directly and volume of the working chamber.

The most widespread use of our mills are a part of the crushing and sorting complex in the beneficiation of coal mining and coal separation into fractions. But often they are used for grinding any other lumpy materials and sedimentary rocks, such as limestone, fire clay, feldspar, shales. Effective are also at crushing of construction waste, broken bricks, limestone, tiles, breeze blocks, foam concrete and concrete rubble.

The efficiency of the toothed crushers depends on the fragility of the material being processed, because the action of the crusher of this construction principle is to blow the material crushing or bending of the toothed rotor and between casing and abrasion and crushing. At the same time capture the pieces takes place at a rate of 1.5-4 times smaller than the diameter of the roll.
