The Rexworks Model 425G Portable Horizontal Grinder is a key piece of equipment in an extremely environmentally and economically profitable industry: asphalt and asphalt shingle recycling. Asphalt is 100% recyclable, and recycling the asphalt-cement in shingles benefits asphalt producers by reducing AC costs and improving the quality of their product, as well as reduces the nation’s dependency on foreign sources of oil and clears up valuable landfill space for products that can’t be recycled and reused. Asphalt shingles can be recycled into a variety of products, including hot mix asphalt, cold patch, dust control on rural roads, temporary roads and driveways, aggregate road base, new shingles and fuel.
Along with asphalt shingle recycling, this horizontal grinder can be used to process a variety of other constructing and demolition runoff material such as wood, metal, cardboard and concrete. Runoff slabs of concrete can be crushed down and used as erosion control, landscaping stone or mulch and retaining walls. If ground down small enough, it can be reused as the base layer to gravel roads or construction projects, or as the dry aggregate to create new concrete. Recycled wood is used for anything from shoreline erosion prevention products to fish and bird habitats to reusable mulch for trails, landscape, gardening and playgrounds. The already existing markets coupled with the constantly evolving technology puts reusable construction/ demolition debris in high demand. And, as more and more information comes to light on the environmental and economic benefits of recycling this material, rather than landfilling it, the country can expect to see more and more RAS and C&D recycling plants popping up in the near future.
Grinders use abrasion and compression to pulverize materials to a reduced size, using a series of wheels, drums and plates to process the material. Grinding and shredding materials in preparation for recycling is growing in profitability. Getting a wide variety of sized and shaped material down to a consistent and more manageable size is the first step in recycling that product. And, with many states passing ordinances on the proper way to dispose of waste and regulations on what can and cannot dumped in a landfill, the shredding and grinding industries are more profitable than ever.
The Rexworks Model 425G Portable Horizontal Grinder is powered by a 425 hp Cat diesel engine and comes complete with Rexworks Rapid Ram feed system.
