Filter presses are used to separate metals from the sludge or slurry produced during the battery recycling process. The sludge is created from the crushing or grinding of the batteries, which are then mixed with chemicals and water in order to remove the metals. The sludge containing the metals to be recovered is fed into the filter press, which features a pack of recessed plates that when closed together form a series the chambers. As the sludge fills the chambers, the liquid filters through the cloth on the plates while the solids remain inside the press. At the end of a filtration cycle, the plates open and the dewatered solids with the recovered metals are discharged.
Diefenbach engineers filter presses specifically designed for lead-acid and lithium-ion battery recycling. Diefenbach's iONIC filter presses feature a specialized coating to process the press and its components from the highly acidic and corrosive sludges produced during the battery recycling process. These filter presses offer durability and long service life.
