4PG four roller crusher
Product overview:
Four roll crusher apply to compressive strength less than 300mpa, the water is less than 30% of the solid material crushing operation, such as coke, coal, ceramic raw materials, ores and water slag, gypsum, clay solid materials, with the use of maintenance costs low, broken than large, reliable performance, little dust, low noise characteristics.
Four roll crusher of four roll surface points for welding and surface or a flat surface of roller, according to user requirements of size selected combinations, applied to the feed particle size less than 90mm, finished product size requirements 0.2-10mm of finely homework. Such as iron and steel plant broken coke; coking plant broken coal; quartz industry broken quartz; iron ore crushing iron ore, etc.; or similar to the above occasions.
working principle
Four roller crusher is the use of four high strength wear-resistant alloy roller, the relative rotation of the high extrusion force and shear force to break the material. The material enters into the two roller type V after crushing cavity by two and relative rotation of the extrusion of, for the first time, the grinding material jiga and mesh (thick broken), and then enter the relative rotation of the two and, second jiga, (crushing) milling for shear and mesh broken into required size from discharging mouth eduction.
