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.

Black mass is an active powder containing a mixture of cathode and anode materials. It is made up of many metals such as copper, manganese, cadmium, lithium, cobalt, etc., and contains recoverable metal oxides. The objective is to separate each metal from this mass and remove toxins from the material to avoid contaminating the metals. The purer the metal, the better it can be recycled.

A trommel screen (a.k.a rotary screen) is an automated sorting equipment based on material size. The screen opening on rotary screen strictly controls the desired size of the output.

As the cylindrical screen rotates at the constant speed, the rails on screen guide stream materials to move forward. The stream materials smaller than the screen opening fall down on a belt conveyor. The bigger stream materials stay and go to proceeding steps.

Applications

This application is widely seen in waste management and mining industry. Hengyang  deploys trommel screen in the primary sorting at the beginning of a recycling system. Its aim is to obtain stream materials at a wanted size and to remove abundant of contamination such as dirt, sludge and sands.

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.
