In order to improve the crushing ratio of pulverizer, to reduce the area and reduce the number of materials, operation and simplify operations, produced three and four-Roll Pulverizer Roll Pulverizer. Three Roll Pulverizer is essentially a single-roll pulverizer and a double-roller pulverizer overlap with the same four-roll pulverizer are from two sets of twin-roll pulverizer made up of overlapping. Four Roll Pulverizer apply to broken coke, limestone, marl, chalk, slag and other materials. Four Roll Pulverizer structure by the two specifications are the same twin-roll pulverizer components overlap.

Materials to the entrance and exit into the four-roll pulverizer, the subject of the crushing roller and the bottom of nesting. A roller bearing is fixed; other roller bearings from the spring to compress pads, springs are pulverizer device. Motor through reducer and coupling driven roller, in which a motor driven roller at the upper right, another motor driven roller lower left, and each roller with the other end of the spindle pulley. Right upper roller of the driven pulley of the lower right roller pulley, so that the lower right roller rotation; lower left of the roller pulley, driven lower left of the roller pulley, so that left turning roller. Events bearings as a result of movement direction perpendicular to the direction of belt drive, the activities of the mobile bearing belt tension when no big change. Material through the upper and lower rollers pulverizer two after discharge from the bottom of the plane. The machine itself with two sets of rollers turning Paper cutting device. When the smooth roll skin or wear a trench, pit, after the demolition of roller do not have to have a direct bearing on the use of cutting devices roller refurbishment, renovation, it will be cutting device installed in the turret on the go, and then linked to the sprocket on the chain . This repair method can reduce the parking time, improve equipment operating rate, to ensure that the entire roll surface light, broken Product uniform particle size.
