The Pre-Shredder is a low-speed, high-torque, twin-shaft shredder. Its special tool geometry makes it suitable for the tearing pre-shredding of particularly bulky or large-volume materials (e.g. wood, building rubble, domestic, industrial, commercial and bulky waste).

The two rotor shafts take hold of the input material. The shafts alternately rotate inwards and outwards. Each shaft is equipped with a row of tearing tools. The rotating tearing shaft assembly is embedded in a stationary tearing table. Scrapers on the table hinder the material from winding up or adhering to the machine. The shredding takes place between the rotating tearing tools and the stationary table. In the process, the machine automatically carries out a sequence involving different directions of rotation. As soon as the input material has reached the desired size, it exits the machine through the bottom.

The machine housing consists of an extremely robust steel construction. The design of the bearing shell bridge is particular to BHS and allows the rotor shafts to be exchanged quickly. The rotating and stationary tools consist of high-quality materials; simple resurface welding allows them to be refurbished. The drive system has generously dimensioned hydraulic drives. The machine is low-maintenance and optimized for a long service life.
