Lithium-Ion Battery Waste Trommel Screen machine 400V 415V 220V

Batteries: alkaline batteries, lithium batteries, saline batteries (rechargeable or not), must be sorted, dismantled, crushed and separated once used. Plastics and metals will be separated and then crushed, ready to be recycled in other processes.

A trommel screen, also known as a rotary screen, is a mechanical sieving machine used primarily in the mineral and solid waste industry to separate materials. It usually consists of a perforated cylindrical drum that rises at an angle at the feed end. Physical size separation occurs as the feed material spirals down the rotating drum, with material of size smaller than the opening of the screen passing through the screen, while material of larger size passes through the drum. It is discharged from the other end.

Trommel screen (rotary screen) is applicable to sort out metals, plastics, rubber and woods according to your desired size. In the meantime, the rotary screen removes metal scraps and dirt. The complete robust construction delivers a reliable size control.

The conducted mechanical processes were thoroughly investigated by experiments in a laboratory and within technical scale, describing gas release of aged and non-aged lithium-ion batteries during dry crushing, intermediates, and products of the mechanical separation. Conclusively, we found that applying a second crushing step increases the yield of the coating materials, but also enables more selective separation. This work identifies the need for recycling of lithium-ion batteries and its challenges and hazard potential in regards to the applied materials. The outlined results show a safe and ecological recycling process with a material recycling rate of at least 75%.
