At the show, BHS-Sonthofen will focus on the fine processing of various metal-containing residues, such as Automotive Shredder Residue (ASR), e-scrap, and incinerator bottom ash (IBA). BHS-Sonthofen has further developed its fine preparation process with extensive tests, thus further improving output quality, mentions the company.

The process works just as well for ASR, taking into account material-specific requirements, as it does for the fine processing of all other metal-containing materials such as electrical and electronic scrap or cable remnants, adds the firm.

New hammer design of the rotor impact mill – higher output quality

The heart of the fine preparation process is the rotor impact mill, which the company is presenting with a new hammer design at the trade show. The RPMX type rotor impact mill is a high-performance crusher unique in its field, setting standards in fine processing and metal recovery with its impeller rotor and special anvil ring. The machine reliably separates material composites and removes cable sheathing and other substances that adhere to metals, opines the firm.

The new hammer design of the rotor impact mill significantly optimizes disaggregation and shaping of the output – while simultaneously reducing wear. Due to the improved output quality, fewer or shorter passes are required, which results in higher throughput. In addition, BHS is presenting a new maintenance concept for the machine that simplifies maintenance and inspection work by the operator and, in combination with the new hammer design, ensures high machine availability, shares the company.

Proven, innovative recycling process for lithium-ion batteries

The company’s second focus is on the recycling of lithium-ion batteries. For this purpose, the company has developed a complete mechanical solution that focuses on a high recovery rate of the resources it contains. The process has already been tested worldwide in existing reference plants run by prestigious customers. Thanks to the consistently inert process, from the crusher to the dryer, hazards such as fires or the escape of toxic gases can be avoided.

Trade show visitors can expect to see the HTC 140 type horizontal dryer used in this process. In the process, the dryer applies a vacuum and heats the pre-crushed batteries to safely evaporate potentially toxic components. The crushed batteries are no longer hazardous after the drying phase, mentions the firm.

Separation technology and pre-shredder round off trade show presentation

From the new technological field of separating, sorting and classifying technology, a separating table from BHS and RW Recycling World will be on display at the event. BHS rounds off its trade show presence with the virtually exhibited Rapax pre-shredder. The powerful machine, which was launched last year, can be used universally: In its various designs, it is suitable for processing metal fractions, commercial and industrial waste, and construction waste. With this machine, the firm combines design and function and takes pre-crushing to a new level.
