The pre-shredder of type VSR is a low-speed, high-torque twin-shaft crusher. Each shaft is equipped with rotating tools that reliably tear the feed material. 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).
The machine is equipped with a large, central infeed hopper. In addition to standard solutions, customer-specific hoppers are also available.
The machine housing is designed as a highly robust, one-piece, welded steel construction. This allows the machine to absorb extremely high forces without difficulty.
Shredding takes place between the shafts equipped with tearing tools and on the tearing table, or a crossbeam and scraper. The machine can be equipped with tearing tools specifically suited to the feed material. These tools differ in diameter and shape. The tearing table is built in a way that accommodates this variety.
Each shaft is powered independently. The machine drive can be driven hydraulically or electromagnetically. In both cases, the drive system consists of standard industrial drives and a variable speed controller. The control and drive system can alternate the rotor direction to adapt to the shredding material.
A hydraulic pusher device is available as an option. It ensures continuous material infeed when processing low-density, light or bulky feed stock.
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.
