the primary crusher. DEFINITION The primary crusher selection is the key to the success of any mining operation that involves the reduction in size of the ore. The crushing plant can be provided with almost any type of primary rock crusher. The rock/ore determines the type of crusher. The plant capacity determines the size of the crusher.

The output size of the material processed also varies depending on the crusher type. Primary crushers produce large output sizes, usually between 1.5 meters and 30 centimeters in diameter. Secondary crushers, on the other hand, typically have smaller output sizes ranging from 0.1-3 centimeters. Primary Crusher Functions and Features
