Double Roller Hammer Crusher

Material is fed by gravity into the center of a double rotor machine and is hit by the hammers. This impacting of feed material against two counter rotating sets of hammers is the primary means ofsize reduction. Other impactions further break the material on an anvil block situated between the rollers. A grid of bars parallel to the hammer’s path can be placed above the rollers. These act as a screen preventing oversize material falling between the rotors. The hammers path is between the grid bars and reduces these blocks so that they can fall into the crusher. Material is crushed in two ways, first by impact on the hammers and breaker plates. Then by attrition and shear where there is slight clearance between the hammers and the screen bars. This zone is the final sizing area for the product. Some makes of double roller hammer crushers use only the dynamic impacting action of one set of hammers to the other. The advantage of using this method is that in reducing wet sticky materials there is little for it to stick to in the crushing chamber and therefore power consumption will be relatively low.
