Two- or three-shafts pre-shredders – ZDS & ZTS ranges
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.
Supplied with an output of 25 to 120 tons per hour (according to the model and products to be processed), pre-shredders are used to control the grading and quality of products prior to feeding into a shredder.
Improved shredder production by preparing a homogeneously graded, densified product, reducing shredding time.
Significant reduction of explosions in the shredder.
Detection of unshreddable material upstream from the shredder.
Increased service life of wear parts in the shredder.
Smoothing of shredder electricity consumption.
Optimized logistics for collecting products to be processed, by reducing intermediate handling and transport volumes.
