Primary Crusher vs. Secondary Crusher: Understanding …
Without a primary crusher, the entire process of crushing would be difficult, costly, and time-consuming. Therefore, the primary crusher is a critical component of any mining or construction operation. Types of Primary Crushers. Explanation of different types of primary crushers, including jaw crushers and gyratory crushers.
Jaw Crusher
A jaw crusher is a compression type crusher, usually used as a primary crusher set at the very front of the ore or rock crushing plant to reduce hard rock size. Jaw rock crushers are commonly double-toggle jaw crushers, composed of a fixed jaw and moving jaw, the discharging stone particle size can be controlled by changing the discharge port.

Crushing in Mineral Processing
Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.
Crushing Plant Design and Layout Considerations
Mine haul-truck capacity is an important factor at primary crusher installations, because it is cost-effective to integrate truck cycle time at the crusher station with mine/shovel operations. If a primary crusher dump pocket is undersized and unable to handle the mine's trucks, then operators must slowly meter the ore into the receiving hopper.
