Weima - Pre-Cut

Weima Pre-Cut Shredder

The Weima Pre-Cut shredder is a single shaft pre-shredder. It is the ideal first step for a multi-stage waste processing system with high throughput. Historially, Weima has manufactured post-shredder for the waste industry. However, they have now taken their years of experiance in this arena to bring to market a pre-shredder capable of delivering quality homogenous outputs.

This industrial shredder ensures optimum pre-conditioning of materials, ready for further processing steps such as sieving, classifying and separation.

The Pre-Cut is built to handle a wide range of unsorted, highly contaminated waste streams. Particle sizes of 150-400mm are achievable. Its castellated floor allows for optimum guidance of the materail to the shredding chamber, with a hydraulic feeding system. The shredder uses a Siemens SPS Control system for easy usability.

Heavy-duty construction ensures the Pre-Cut industrial shredder is tough enough for demanding environments and applications, featuring offset bearings, bolted hardened stub shaft, vautid rotor, hydraulic cooling, super-fast hydraulics, 40mm plate base frame and anti-vibration substructure.

The Weima Pre-Cut can function as single-stage shredder, in instances that an RDF producer only requires coarsely pre-shredded material.
