— The primary crusher's function is to reduce the size of the rock or stone for easier handling and transportation. The primary crusher is usually a jaw crusher or a gyratory crusher, which operates by compressing the material between two surfaces. The jaw crusher works by moving the material between a fixed and a moving plate.
The single-toggle jaw crusher has less shafts and bearings compared to double-toggle jaw crushers. Only one toggle goes from the bottom of the swinging jaw back to the fixed point. Double-toggle jaw crushers. In a double-toggle jaw crusher, the moving crusher jaw is driven by the eccentric shaft that moves the front and rear toggles up and down.

For instance, if the final size of your product only needs to be between 4 inches and 6 inches, a primary jaw or impact crusher can accomplish your goals. However, you will likely require a much finer product, and that means incorporating up to three—or even four—stations with a variety of crusher types. 1. Primary Crushing
Gyratory Crusher Operation Crushing action is produced by the oscillation or ' throw ' (opening & closing) of the gap between the moving mantle liner, mounted on the central vertical shaft ( spindle ), and the fixed concave liners mounted on the mainframe ( …
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) Feed Rate: 160 to 13,000 tph
— The impact device more nearly approaches actual crusher operation, both in velocity of impact and in the fact that broken stone is used in testing. The average impact crushing strength is an indication of the energy required for crushing, while the maximum compression values indicate the danger of crusher breakage and the type of construction ...
Depending on the size reduction required, the primary jaw crushers are followed by secondary and tertiary crushing. The last crusher in the line of operation operates in closed circuit. That is, the crushed product is screened and the oversize returned to the crusher for further size reduction while the undersize is accepted as the product.
— The cone crusher is a popular rock crusher in mining operations, aggregate production, and recycling applications. Many users use it for size reduction and shaping of precious metals (e.g. gold, silver, and palladium), concrete, and hard rock.
Size Reduction) A crusher is a machine designed to reduce the size of large rocks to smaller rocks, gravel, sand, or rock dust; this is essential for efficient transport of the product via conveyors etc. Crushing is the first of many stages that lead to separation of the mineral(s) from the waste (gangue) material.Waste material can be discarded or …
Explain how crushing works. Explain the stages involved in crushing operation (Primary, Secondary and Tertiary) Recognize different types of crushing equipment used in …
— For large, heavy-duty operations, a double-toggle jaw crusher is often the go-to. For smaller, less intensive tasks, a single toggle might be more appropriate. How Crushing Forces are Applied. In jaw crushers, the crushing force is generated by the movement of the movable jaw plate towards the fixed jaw plate. This force is a result of …
— It is possible, when required, for a crusher to use a combination of two or three of these principles. The selection or sizing of a crusher is much helped by measuring the rock's hardness during engineering. ... This mechanical operation consumes the energy, and size reduction is merely a result of this energy consumption. ...
— Working Principle of Crushers. On left is a showing of the "standard gyratory with straight concaves" is a section through any vertical, radial plane in the crushing chamber of one of the intermediate sizes of the crusher.
