The following mechanical separation is a combination of air-sifting, crushing and sieving processes. A possible combination and enclosed process influences will be described later on. One product of the mechanical separation is the coating of anode and cathode, the so called black mass.
secondary crushing (although impact crushers are sometimes used), which typically reduces material to about 2.5 to 10 centimeters (1 to 4 inches). The material (throughs) from the second level of the screen bypasses the secondary crusher because it is sufficiently small for the last crushing step.
