Primary crushing is the first stage of material reduction and can sometimes be the only stage needed to generate the desired product for a job.
Electric motors will only draw as much power as the crusher needs. However, the theoretical difference in a 500,000-ton quarry or mine is about 90,000 kW/hours. That reflects only the primary crusher, not the added power it takes downstream to also recirculate 30% more rock through the secondary circuit.
No discussion of primary crusher selection would be complete without a comparison of the two leading types: the standard gyratory crusher and the Blake jaw crusher. Although their fields of application overlap to a considerable degree (at least in the realm of primary crushing) there is no real conflict between these two machines; one …
The crushing of material into smaller loads is usually undertaken in two steps, starting with the primary crusher that includes jaw crushers, hammer mill crushers, and gyratory crushers. Larger stones or mineral ores are used to produce smaller material. Where the material is not reduced sufficiently in the primary crusher, it is then crushed ...
Primary crushers with crush run-of-mine rock from blast product size to what can be carried by the discharge conveyor or fit/math the downstream process. A typical …
While jaw crushers may always be a smart primary crusher stage choice for many operations, it's true that newer cone crushers are increasingly taking their place due to versatility. Cone ...
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill)
The primary crusher is responsible for reducing large rocks to a size that can be further processed by the secondary crusher, which then reduces the material to the desired final product. Efficient primary and secondary crusher operation is essential for smooth crushing operations. The primary crusher must be set up to handle the maximum size ...

Stone crusher machines are equipment designed to crush or break down large stones, rocks, and minerals into smaller pieces, gravel, or dust for various applications. According to the customer's final particle size requirements for crushed aggregate, it has different crushing stages with various machines, including primary crushing equipment, medium …
Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types. 2. Secondary Crushing
Gyratory Crushers. The primary rock breaker most commonly used in large plants is the gyratory crusher, of which a typical section is shown in Fig. 5. It consists essentially of a gyrating crushing head (521) working inside a crushing bowl (522) which is fixed to the frame (501).
The Role of a Primary Crusher in Mining Operations. Primary crushers, such as gyratory crushers, are vital in mining. They pull valuable minerals from the earth and initiate the crushing process. They crush big rocks into smaller pieces for easy handling, with the type of material influencing the choice of crusher. These smaller pieces are ...
