Rotary crushers are machines for crushing the material by impact by means of a rotating rotor with rigidly fixed beaters. They came to the production in Germany in 1942, and in the Soviet Union - in 1956.
Up to the present day rotary crushers have not lost their popularity and continue to be widely used in various industries, because they have a number of positive features, which are absent in other types of crushing equipment.
Most often, impact crushers are used for coarse, medium and fine crushing and sedimentary rocks of low strength, and abrasion. If necessary, high-reinforced grinders for abrasive rock are made. Impact crushers for coarse, medium and fine crushing have different number of reflective plates and beat, size and weight of the housing and the rotor.
Our company manufactures modifications of rotary crushers - rotary toothed crusher. In this crusher, on the main operating member there are 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, prolongs the service, and also allows working with high hardness materials. Size, number of toothed segments, frequency and the order of their location on the rotor can pre-lay a fraction size of the processed material and, ultimately, the performance of the device. The performance is also affected directly by the installed capacity of the engine 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. They are also effective 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 processing material, because the action of the crusher of this construction principle is to blow the crushing material or bending of between toothed rotor and 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.
To work with other, more elastic and viscous materials such as wood, rubber, plastic, various polymers, etc., our company produces more effective types of grinding equipment. These are industrial shredders, hammer mills, chaff-cutter, straw chopper. All equipment is tested and pre-selling preparation.
