The German equipment company BHS-Sonthofen has been commissioned by the Swiss-based company DHZ AG to build a complete plant for processing concentrated metals found in incinerator bottom ash. The plant also will be able to process and refine a wide range of metal-bearing materials. BHS Sonthofen notes that the order is the largest ever for the company’s Recycling Technology division.
DHZ AG, located near Zurich, operates a modern landfill and connected recycling plant, which is used to sort out resources and contaminants from the materials where they are further processed. When operational, BHS Sonthofen’s supersort facility for processing ash from waste incineration plants will be able to handle more than 100,000 tons of ash per year. The system will take up a significant portion of the recycling plant.

BHS-Sonthofen is planning and implementing the entire new supersort turnkey processing plant for DHZ AG in Oberglatt, Switzerland. |
To further process the metals delivered by the supersort facility, DHZ is setting up a new processing plant called supersort metall in a neighboring town. The annex will process non-ferrous metal concentrates originating from customer facilities and the supersort and supersort fein plants of DHZ. In addition, metallic fine fractions derived from shredding vehicle scrap and electronics devices will be further processed there. Lead from backstops can be processed as well.
According to BHS-Sonthofen, the goal of the equipment is to attain high-quality heavy and light non-ferrous fractions from the concentrate, which will be sold to smelters or industrial customers. Each line of the plant has a processing capacity of 10 tons per hour.
DHZ specifically required a provider able to offer a dry processing method because wet processing would have incurred significant additional costs due to the high requirements associated with water and sludge treatment.
BHS-Sonthofen has been commissioned with delivering the machine technology as well as with implementing the entire new plant to full operation in 2016. The delivery scope comprises two entire lines – one for generating particle sizes from 8 to 100 mm and another line for fine processing in the range of 0 to 10 mm. BHS will deliver all components, from feeding systems through to big bag loading stations. The list of components includes various BHS impact mills, sifting machines, zigzag sifters, cyclone separators, magnetic drum-type separators, separating tables, the entire conveyor system, a dust removal system, steel construction works and controlling and visualization.
Machines from BHS-Sonthofen include a PM 0806 impact mill, one RPMV 1113 rotor impact mill and one RPMX 1516 rotor impact mill. The machines process granulates from 8 to 100 mm and produce a fine output with sizes from 0 to 10 mm. As a final step, the processed material is cleanly separated by type and then filled into big bags.
Alfred Weber, BHS-Sonthofen’s sales director for recycling technology, notes the contract underscores the company’s success in offering a continuously increasing range of complete plants. “Our client greatly appreciates that we do not simply deliver individual machines, but rather provide a fully operable plant in turn-key condition.”
Construction commenced in early 2016, and the plant is scheduled to go live this summer.
