Description: Our turn-key system for printed circuit board (PCB) and e-waste processing liberates precious metals and base metals from the plastics and fibers of e-waste and other components, avoiding the use of chemicals for leaching. Using a hammer mill and shaker table, our turn-key system pulverizes the components and separates lighter
