Primary Crusher - an overview | ScienceDirect Topics
Primary crushers are solidly built to receive large lumps of rock directly from the mines and designed for large tonnage throughputs. Basically, gyratory crushers consist of a fixed solid conical shell or bowl (also called concaves) and a solid cone within the bowl called a breaking head (Figure 5.1 ).

Selecting the right crusher : Pit & Quarry
Jul 25, 2018 · The most important characteristics of a primary crusher are the capacity and the ability to accept raw material without blockages. A large primary crusher is more expensive to purchase than a smaller machine. For this reason, investment cost calculations for primary crushers are weighed against the costs of blasting raw material to a smaller size.
Crusher - Wikipedia
Primary crushing reduces the large pieces to a size which can be handled by the downstream machinery. Some crushers are mobile and can crush rocks as large as 1.5 meter (60 inches). Primarily used in-pit at the mine face these units are able to move with the large infeed machines (mainly shovels) to increase the tonnage produced.
Crushers - liming
One of the most important characteristics of a primary crusher is its capacity for accepting feed material without bridging. A large primary crusher is, naturally, more expensive than a smaller one. Therefore, the investment cost calculations for primary crushers are compared together against the total costs of primary stages, including quarry face clearing, blasting, and drilling costs.
Secondary & Tertiary Crushing Circuits
The feed comes from the primary crusher and will have a certain amount of rock that doesn’t need further crushing. To run this ore through the crusher will be a waste of energy and crushing space. Ideally it should be removed. To remove it requires a procedure called “SCALPING”.
Jaw Crusher VS Gyratory Crusher - JXSCMACHINE
Jaw crusher and gyratory crusher as the primary crusher, play an important role in the crushing process. How to choose the suited primary crusher from the jaw crusher? What’s the difference between a jaw crusher and a gyratory crusher? JXSC starts with the following points: structure, capacity, energy consumption, maintenance.
Jaw Crusher - an overview | ScienceDirect Topics
Jaw crushers are designed to impart an impact on a rock particle placed between a fixed and a moving plate (jaw). The faces of the plates are made of hardened steel. Both plates could be flat or the fixed plate flat and the moving plate convex. The surfaces of both plates could be plain or corrugated.
Crushing Plant Capacity - Mineral Processing & Metallurgy
From the standpoint of economical operation, reserve capacity in the primary crusher is just as important here as it is in the commercial crushing plant. Underground mining operations are, in many cases, provided with a substantial surge capacity between the mine and the primary crushing plant.
