Waste processors, contractors and operators as well as haulers and industrial plants managers will be interested in the innovative new shredders targeted at reducing processing, transportation and disposal costs.
Materials are generally processed in steps, including primary and secondary crushing, or pre-shredding and secondary shredding for size reduction. Further reduction processing or screening to a finished size is only performed to add value to specific materials.
The seasoned professional knows that there are no absolutes for clean or consistent waste streams. Waste feed stock materials are generally bulky and come in a variety of weight densities, properties and characteristics. Expectations for processing equipment are high and often beyond their capability. But there are key elements to determine overall success:
Multi-material processing capabilities in a single machine — Shredders such as Schred Max, with its unique single bi-rotational cutter shaft and open grid cutting table, can process virtually any material in the waste stream (including wood, tires, concrete, asphalt, construction waste, carpet, municipal and industrial commercial waste and mattresses).
Tramp iron protection — Primary processing equipment should be built to deal with heavy tramp iron and other unknown elements without machine damage. Schred Max has a proprietary hydraulic drive that has built in protection against tramp iron such as I-beams, bucket teeth, and brake drums.
Efficiency and low operating costs — Primary processing equipment should minimize the processing cost per tonne with small horsepower engines combined with state of the art hydraulics. Slow self-modulating variable shaft rotation speeds allow abrasive materials to fall through the open grid-cutting table to reduce wear and tear.
Schred Max offers three sizes of primary reducers designed to fit into the smallest through the largest operations. Smaller size equipment, such as the Schred Max 56XHD, has a 4 cubic yard hopper and 50 HP power unit with low acquisition costs suited to smaller operations.
