With robust steel construction, the DW 306 accepts industrial and biowaste, construction debris and waste wood.
Due to the wide range of materials that it can process, the machine is of particular interest for recycling companies processing various raw materials.
Peter Schaible, managing director at German-based recycling and recovery firm Gesellschaft für Wertstoff-Verwertung (GWV), says: “All-rounders in this line of business, like us, need machines which can do more.
“Our range of recycling activities is wide. It ranges from construction debris recovery to composting, to woodchip production for biomass power stations – and we extend it continually.”
The Doppstadt Ceron used in the waste wood processing plant of Remseck-based GWV is equipped with a BioPower roller, a medium-size comb basket and an 80mm screening drum. For precision work there is also a flexible Doppstadt machine in use: the stationary grinder NZ 180 with flail drum.
The plant shreds class A1-A4 waste wood at up to 45 tonnes an hour and up to 100mm grain size. Ferrous and non-ferrous metals are separated from the wood.
“Our wood processing method permits the reuse of this bioresource, such as in woodchips of several sizes for applications such as biomass power stations,” says Schaible. “For this task, the DW 306 Ceron is ideally suited.”
The machine, with its fuelefficient planetary gear, can be ready for operation in just a few minutes using a central control panel that has an optional remote control.
After pre-shredding, the material can be transported, with or without screening of, for example, ferrous metals, to the re-shredding process or directly into a box for storage.
If the material is very complex, it can be screened after shredding to a determined average grain size. The fine fraction is transported for storage through the ferrous and non-ferrous separator, and the oversize is re-shredded and separated from metals before it is transported to the collection box.
If it is necessary to shred it again, the oversize can be transported to the pre-shredding unit by a return conveyor. “In this way we can adjust the recyclables recovery to meet the requirements,” Schaible explains.
The whole plant can be operated by just two people. As well as the efficiency of the machines, they have low space requirements because separated metals are transported to on-site storage boxes by conveyors, meaning it is not necessary to set up containers in the hall and empty them several times a day. Schaible adds: “This is one work step less for us and it also increases the operational safety.”
