Horizontal grinders offer many advantages over slow-speed shredders, including superior particle size control, higher production capacity, and better horsepower efficiency. The Rotochopper "Perfect In One Pass" advantage optimizes these benefits by efficiently producing high quality end materials at low operating costs.
A slow speed shredder can be a valuable tool for material recovery and recycling—but the advantages of slow-speed shredders apply almost exclusively to commingled, contaminated waste streams, such as municipal solid waste (MSW), and pliable synthetic materials like rubber tires and carpeting, which will not fragment easily in a high-speed grinding system. Other than these types of materials, most feedstocks used to produce biomass fuels, landscape mulch, compost, and animal bedding can be most economically processed with a high-speed horizontal grinding system.
Typically, shredders are incapable of producing high quality end materials and are used mainly to pre-process raw contaminated wastes. Often when a slow-speed shredder is used for primary processing of contaminated waste, a horizontal grinder is used to process the material into a quality end product. Known for advanced particle size control, Rotochopper horizontal grinders will produce valuable end products from sorted construction debris, pallets, railroad ties, whole trees, round corn stover bales, and many other resources.
Horizontal grinders open more opportunities for low-grade waste materials, allowing operators to produce landscape mulch, biomass fuels, animal bedding, refuse derived fuels (RDF), and other valuable finished products with size and texture specifications that shredders usually cannot achieve. Exclusive Rotochoppper technology, like our 1-pass colorizer and our bale pre-processing system, make our horizontal grinders the most versatile equipment on the market.
Often, for materials like construction and demolition debris (C & D) and municipal solid waste (MSW), the most profitable recycling method is to pre-sort the recyclable fractions using a picking line or batch sorting methods, then feed the grindable feedstocks into a horizontal grinder. Rotochopper electric horizontal grinders provide the uptime and particle size control required to process sorted C & D and sorted MSW, making them a popular choice with transfer stations, material recovery facilities, and landfills. Our portable and track-mounted diesel horizontal grinders provide the same "Perfect In One Pass" advantage for companies needing mobile grinding capacity.
