Shredder, granulator and shear: choosing the cutting stage

A recycling line can combine several reduction equipment. Choosing the tool begins by identifying the function of each stage and the size of material that must be delivered to the next process.

Shredding: preparing the material

The shredder is used to reduce volume and prepare input waste. Its cutting system, number of axes and configuration are selected according to the material and application. The teeth, separators and counterblades form an assembly that must retain its functional geometry.

Granulation: control the final size

The granulator mill combines rotor blades, fixed blades and sieve. The state of the cutting edge and the adjustment of the assembly must be studied with the feeding and the behavior of the material. The appropriate configuration depends on the equipment; There is no universal clearance for all mills.

Shearing: cutting a defined section

Shearing works on specific pieces or flows and requires studying material, thickness and support. Your blade selection cannot be extrapolated directly from a grinding tool.

Data to select spare parts

Provide brand and model, reference, input material, photographs and required output size. The documentation UNTHA RS30/40 and the documentation NEUE HERBOLD SM show examples of different equipment; They do not prove compatibility of a spare part without verification.
