GEP Ecotech hydraulic primary shredder is one of the main shredding equipment with high production efficiency for solid waste shredding, which is mostly used in the first process of various solid waste shredding. The two-shaft shredder is mainly composed of main shaft, cutters, middle counter cutters, shredding chamber, power system, etc. The cutter rollers are directly driven by low speed and high torque dual hydraulic motors. The material is treated by shearing, tearing and pulling by the interaction between the moving cutters and the middle counter cutters. It has the characteristics of large crushing force, high output, low noise and good stability. Usually used in various solid waste crushing treatment, domestic waste crushing treatment, waste volume reduction and other fields; wide applicability of materials, high crushing efficiency.

Pre-shredders are generally installed upstream from a shredding system to prepare the material for entry into the shredder. Adding a pre-shredder to the metals process allows the operator to control the feed rate, leading to a more uniform flow of material through the shredder itself, and a higher density product. With their first-rate tooth profile and very high torque, GEP Ecotech pre-shredders are truly essential for processing waste metal such as end-of-life vehicles, domestic waste, WEEE, etc. in bulk or baled form.

The pre-shredder is a low-speed, high-torque twin-shaft crusher. Each shaft is equipped with rotating tools that reliably tear the feed material. Each shaft is equipped with rotating tools that reliably tear the feed material.

Pre-shredders are efficient waste processing machines utilized in recycling and waste processing applications. The machine is suitable for the pre-shredding of particularly bulky or voluminous materials (such as domestic, industrial, commercial and bulky waste, as well as construction waste).


Both rotor shafts engage the feed material. The shafts rotate alternately inward and outward. Each shaft is equipped with several tearing tools. The rotating tearing tool is surrounded by a stationary tearing table, or a crossbeam and scraper. Shredding takes place between the individual rotating tearing tools and the stationary assemblies. In the process, the machine automatically carries out a sequence involving different directions of rotation. As soon as the feed material has reached the desired size, it exits the machine through the bottom.
