The Ludman roll crusher or granulator is a widely used size reduction unit that can successfully process a variety of materials. The differential speed of smooth or corrugated rolls permits the production of a narrow range of particle sizes with a minimum of objectionable oversize and undersize particles. Roll crushers or granulators are more efficient than chain mills, hammer mills, cage mills, and others. The roll crusher is designed for a gradual size reduction in one, two, or three stages per unit, depending upon the ratio of feed size to desired finished product size. With proper selection of roll speed and differential, roll separating force, roll clearance, and number and type of corrugations, the roll crusher may be arranged to granulate, grind, pulverize, crack, crumble, or fracture an unlimited number of materials, chemicals, minerals, and plastics.
