base material. The stone that is too large to pass through the top deck of the scalping screen is processed in the secondary crusher. Cone crushers are commonly used for secondary crushing although impact crushers are sometimes used, which typically reduces material to about 2.5 to 10 centimeters 1 to 4 inches.
Cone crushers are commonly used for 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.
