double roller teeth crusher machine/twin roll crushing equipment for coal crushing and power plant industry

Product Description Double roller teeth crusher, also known as double roll teeth crusher, belongs to traditional crushing equipment. It is mainly used for fine processing of material particles. As the main working part, the two cylindrical rollers rotate oppositely to achieve the purpose of crushing. Due to its peculiar tooth crushing structure, it is also called Teeth Roll Crusher.   As the name implies, double roller teeth crusher is a kind of roll crusher that has dual rollers. Doule roll crusher is capable of secondary or fine crushing of materials with less than 35% moisture content and 300Mpa comprehensive strength, such as limestone, coal, granite, basalt, dolomite, ores, construction waste, cement clinker, etc. Double roller crusher is widely used in coal, mining, cenment, ceramics, metallurgy, chemical industry, building materials and other industries, which has the advantages of low maintenance cost, reliable performance, little dust, low noise, etc. Double roller teeth crusher has similar working principle to roll crusher. The teeth rolls are made of special wear-resisting materials. Driven by the electric motor, the two teeth rolls will rotate in relation to each other with high speed, and the materials are sent in from the top feeding mouth and will fall into the space between the two rolls and then the materials will be squeezed and crushed. The crushed materials will be discharged from the bottom of the machine.   Structure Characteristics of double roller teeth crusher 1. Double roller teeth crusher(roll teeth crusher) is mainly composed of roller, roller support bearings, pressing and adjusting device, and driving unit. 2. The adjustment of discharging granularity: a wedge or gasket adjustment device is set between the two rollers; the top of wedge device is equipped with adjustment bolt; when adjusting bolt pulls up wedge device, the wedge device will separate movable roller from fixed wheel, so the clearance between two rollers largens and discharging grain size become larger; when the wedge pulls down, clearance between two rollers diminishes and discharging grain size become smaller. 3. The driving mechanism is made up of two motors which drive roller through the transmission of triangle belt and rotate to relative directions. 4. For the sake of safety, transmission parts of roller crusher should be installed with safety cover according to the actual situation. Technical Parameter of the double roller teeth crusher
