The working principle of the rebar granulator is based on a combined shearing and extrusion action. The equipment typically consists of a feeding system, a cutter roll assembly, a power transmission unit, and a screening mechanism.
Regarding the selection of materials for the cutter rolls, priority is placed on wear resistance and toughness; materials such as high-manganese steel or alloy tool steel are commonly used, with hardness enhanced through heat treatment. Furthermore, the precision of the blade clearance adjustment directly affects the uniformity of the granule size; manufacturers with precision machining capabilities can control cutter roll concentricity to within 0.05 mm, thereby minimizing vibration and noise during operation.
