Secondary Crusher. These crushers break down materials into smaller sizes and often have a reduction ratio less than 3:1 in crushing. A secondary impactor, hammermill, and cone crusher are popular secondary crushers. Still, note that you may use a jaw crusher as a secondary crusher in some cases. Tertiary Crusher

ABSTRACT. Cone crushers are used in the mineral, mining, and aggregate industry for fragmentation and production of rock materials. Cone crusher control systems are widely used for machine protection, wear compensation and, to some extent, increasing production. These systems ordinarily focus on the crusher and not the yield of …

Crusher Reduction Ratio. I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.

It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.

The minimum distance between the mantle and concave is defined as the closed side setting (CSS) of the cone crusher. The CSS is easily changed online in a large variety of commercial crushers; different principles of CSS adjustment are described in (Quist, 2017).The maximum distance between the mantle and concave, on the other …

This research involves the optimization of aggregate production using the Taguchi approach to maximize the production rate of Gneiss stone. The L18 orthogonal array has been used to investigate how the CSS, throw, eccentric speed, and particle size affect the products of the cone of the crusher (its cumulative weight fraction). The CSS, …

Most cone crushers have a feed opening size of 5-14", so material that's larger than the maximum size allowable will need a first stage of crushing before they can be fed into a cone crusher. Final Product Isn't Uniform. Cone crushers do an excellent job of providing finished material that's relatively homogenous.
