It is suitable for medium hardness and soft materials with pressure strength less than 200Mpa and humidity less than 30%, and it requires fine and medium crushing operations with less particle size and more granular size. Such as coal, coke, chemical fertilizer raw materials, petroleum coke, glass tubes, chemical raw materials and other solid products, the machine design is reasonable, the use of maintenance cost is low. The crushing ratio is large. Reliable performance, low dust, low noise.
The four-tooth crusher is equipped with four grinding sets, the upper two sets are the tooth sets, the lower two sets are the surfacing welding sets (or flat roll surfaces), which is suitable for the medium crushing operation with the feed particle size less than 700mm and the finished product particle size requirement of 2-20mm. Such as the crushing of coal for common boilers in vulcanized bed boilers in thermal power plants, the crushing of fertilizer raw materials in chemical fertilizer plants, the crushing of waste glass tubes in the solar industry, etc., or the working principle of crushing occasions similar to the above
Four-toothed roller crusher is the use of four high-strength wear-resistant roller, relative rotation of high extrusion pressure and shear force to break materials. After the material enters the gap between the upper two teeth rollers (V-shaped crushing chamber), it is squeezed and shear by the relative rotation of the two teeth rollers, and the material is squeezed for the first time, and after shear (rough breaking) it enters the next two sets of relative rotation again, and then rolled by the lower two. Shear, and grind (fine break) into the desired particle size from the discharge port.
