What is the difference between a jaw crusher and a cone crusher? Primary vs. Secondary Crushing: Jaw crushers are primarily utilized for initial material reduction crushing tasks, while cone crushers are used in secondary crushing, refining materials that have already undergone primary crushing stages.
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
Wide application: Suitable for both dry and wet crushing, for materials with up to 15% moisture. One-time forming: Eliminates the need for primary and secondary crushing, …
impact crusher. Impact crushers can be used as primary crushers, secondary crushers or tertiary crushers depending on the size and technology. They are equipped with beaters, also called hammers, and impact plates. They operate in the following way: they are fed from the upper part, then the stones are hit by the hammers and projected towards the plates.

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.
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.
Jaw Crusher Reduction Ratio. Either an 8-to-1 or 6-to-1 ratio should be the target reduction ratio for maximum jaw crusher efficiency. This setting typically provides an ideal P80 factor—when 80% of crushed material produced by primary crushing will pass screening after processing.
