SHARE

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, Danieli Centro Recycling pre-shredders are truly essential for processing waste metal such as end-of-life vehicles, domestic waste, WEEE, etc. in bulk or baled form.
