First, an overview
Four teeth roll crusher suitable 240Mpa on compressive strength of less than and the water content of less than 30% of the solid material, and size requirements less powder, particle crushing and crushing operations. Such as coal, coke, fertilizer raw materials, petroleum coke, glass tube, chemical raw materials and other solid materials, with the use of low maintenance costs, large crushing ratio, reliable performance, less dust, low noise characteristics.
Four toothed roll crushing machine is equipped with four roller crusher, and tooth roller surface, and roller surfacing (and plane or straight tooth optional) for small particle size 700mm, finely finished product size required 2-30mm. Such as thermal power plant boiler fluidized bed boiler, ordinary broken coal; chemical fertilizer plant fertilizer raw material crushing; solar industry crushing waste glass tube; or the similar occasions.
Two, work principle
Four roll crusher is crushing roller with four high-strength wear-resistant, high pressure and shear force to squeeze the relative rotation of the crushing material. The material enters into the two toothed roll gap (V type of crushing chamber) by two teeth and relative rotation of the extrusion and shearing action, for the first time the material jiga, sheared (thick broken), once again into the relative rotation of the two and, by two and rolling, shearing and meshing grinding (thick broken) into the required size is discharged from the discharging opening.
