Condition: new, In every economic and public sector calculation, waste transportation is a critical factor. Here, it is not so much the weight but rather the volume that matters. The continuously rising transport costs for this waste are becoming an increasing economic issue. Proper disposal of large quantities of polystyrene or packaging film is particularly important in the retail sector. The VOLUME REDUCER ensures a volume reduction of up to 80 percent at this point. Bottles of any type and size, e.g., sparkling wine bottles, can be shredded effortlessly without the need for a compression mechanism. It is also possible to unpack expired food products. Furthermore, reject items such as pharmaceuticals, data carriers, or counterfeit products can be rendered unusable. Food residues and organic waste, including bones, can be shredded, collected, and converted into electricity and heat in biogas plants using the VR60. Consider, for example, a reverse vending machine for deposit bottles. PET bottles are compressed and held under lock and key until collection due to the presence of a barcode. By using the VOLUME REDUCER, the barcodes on PET bottles could be made unrecognizable, thereby achieving significant volume reduction. The shredded bottles could then be collected in a large container, eliminating the need for daily collection at return points. The shredder's vertically moving, wear-free blades ensure a quiet and clog-free operation. ALL ADVANTAGES AT A GLANCE - Non-rotating shredder - No material entanglement thanks to non-rotating blades - Automatic feed through blade movement - Automatic reversing V-shaped blades prevent jamming or blockage - Fast component change thanks to modular system - Intelligent control via compact logic system (PLC) - One-button operation - Optional material discharge via conveyor belt - Shredder module can be integrated into existing systems - Low blade wear and maintenance costs due to highly abrasion-resistant steel with a nominal hardness of 600 HBW VR60 IN DETAIL - Dimensions: 90 cm x 70 cm x 85 cm Nodpfoyr I H Ujx Aa Rslf - Weight: approx. 190 kg - Power consumption: 3 kW - Connection value: 400 V three-phase alternating current
