BHS-Sonthofen introduces mobile recycling system for e-scrap

BHS-Sonthofen of Sonthofen, Germany, has developed the new, compact and modular Eco-Impact mobile recycling system designed for throughputs of up to 2 metric tons per hour and for use at different locations.

The Eco-Impact system crushes obsolete electrical and electronic equipment and includes a complete manual sorting line as well as an automatic separation system for ferrous and nonferrous metals, BHS-Sonthofen says. As such, the system is ideal for use in regions where the large-scale recycling of e-scrap has not yet been established, the company adds.

BHS designed the system for electrical and electronic equipment with dimensions of up to 500 x 500 x 500 millimeters and weighing up to 25 kilograms.

At the heart of the Eco-Impact system is the new RS 1109 Rotorshredder, which the company says crushes the old equipment while separating composite materials so that individual components can then be removed via both the manual sorting station and the automatic separation system. At the end of the process, the material has been sorted into motors, armatures, copper pellets, capacitors, batteries, PCBs and—depending on configuration level—ferrous and nonferrous metals, BHS Sonthofen says.

The Eco-Impact comprises two modules arranged on two container platforms with dimensions of 5.8 x 2.3 x 3.0 meters (L x W x H) each. The company says it is compact enough to be easily transported from one location to another by truck. Once it has arrived, it’s ready for use within just a few minutes, the company says.

Alfred Weber, head of sales for the Recycling Technology division at BHS-Sonthofen, describes the system as a starter package.

“We see the Eco-Impact as the most affordable way of entering the field of e-scrap recycling, both with regard to the low investment costs and to operation. The system is ideal for locations where large-scale recycling has not yet been established or is not possible from an economic point of view. The crushing process—which is very difficult to achieve manually—is carried out by the machine. The sorting process—which would require a level of technology that is simply not justifiable in the case of small volumes of scrap—continues to be carried out by workers.”

The first module contains the material input system (conveyor belt), a BHS type RS 1109 Rotorshredder, the drive elements, a dust extraction system and the entire control system.

The new BHS type RS 1109 Rotorshredder comprises a cylindrical work chamber with a vertical shaft. Hinged working tools are arranged in pairs, one above the other. The centrifugal force aligns them horizontally and stabilizes them. The input material is fed into the work chamber from above. When it enters the crushing radius of the tools, it is subjected to extremely intensive impact, collision and shearing forces, the company says. Because the material is only in the rotor chamber of the machine for a short period of time, there is no thermal stress, the company says, so plastic parts can be easily separated from other materials.

All parts that come into contact with the input material are made from wear-resistant steel and are designed to be easily replaced. The power consumption optimizer of the Rotorshredder harmonizes the relationship between the required power, torque and required current, resulting in lower energy costs, according to the manufacturer.

The input material is placed into the conveyor belt input box manually and is fired against the inner wall, which is clad with sturdy Hardox plates, with an enormous striking force by the fast-rotating impact tools of the Rotorshredder. The impact crushes the input material and separates composite materials.

The shredded material is crushed so that most of the components are exposed, however batteries and capacitors are not destroyed, the company says. The second module has four stations for manual sorting. It consists of the conveyor belts, a magnetic separator and storage containers for the sorted material. At the end of the sorting line, a magnetic separator removes the ferrous material.

An optional automatic separator for nonferrous metal is also available, the company says.
