GCS Waste Density Wizard Density Separators
GrinderCrusherScreen (GCS), Smyrna, Ga., has introduced the GCS Waste Density Wizard 1000 and 1200 models of density separators. The patented machines are designed to take a commingled product such as a mixture of wood, rocks, dirt and plastic and separate it into piles of similar products, according to GCS.
In a news release, GCS says the Waste Density Wizard consists of only one machine that will screen the material, air separate the light film plastic or paper, water separate the rocks from the wood and pull out the sludge.
“At GrinderCrusherScreen we deal with recyclers from across the U.S. and overseas, and the demand for one machine to separate fines, film plastic/paper, rocks and wood is a common need,” says GCS president, Neal Kaiserman.
“Until recently, customers would have to use picking stations and other technologies to achieve this task,” says Kaiserman, adding that one would have to be extremely “dense” not to see the value of the machine.
The Waste Density Wizards are designed to handle mixed C&D materials, scrap wood, municipal solid waste (MSW) and compost.
At mixed C&D facilities materials are sometimes shredded by a high-torque, low-speed shredder to simplify the hauling process, notes GCS. Once this commingled material comes into the C&D facility, GCS recommends the material be run through a screening plant to remove the material larger than 12 inches and also remove the fines (under one-half inch).
Remaining material can be run under a magnet and inert separator and into the Waste Wizard, resulting in a pile of wood, a pile of plastic, a pile of aggregate, a pile of excess dirt and a small pile of sludge, says GCS. The resulting wood will be marketable to be used for fuel and the aggregate for construction, the company adds.
For MSW, the Waste Density Wizard can separate glass from plastic, remove film plastic such as plastic bags and can separate many other materials, says GCS.
Compost sites have issues with film plastic and rocks in their material. For composters currently producing a finished screened material that still has small pieces of plastic bags and rocks in the material, the “overs” can be run directly from the screening plant into the Waste Wizard to remove the contaminants, according to GCS. The clean wood can be returned back to the windrow, allowing for “considerably cleaner compost,” says the company.
