Indirect Particle Size Distribution Control in Cone Crushers

01/01/2013  CONCLUSION This work introduced two methods for indirect regulation of cone crusher product-size distribution: Specific energy consumption (SEC) control and ratio control of selected product fractions. It also introduced a cascade scheme that combines the desirable parts from both schemes. The basic idea behind ratio control is to regulate the crusher product-size distribution by

Cone Crusher - an overview ScienceDirect Topics

This is also called interparticle crushing. The gyratory crushers are equipped with a hydraulic setting adjustment system, which adjusts c.s.s. and thus affects product size distribution. Depending on cone type, the c.s.s. setting can be adjusted in two ways. The first way is by rotating the bowl against the threads so that the vertical position of the outer wear part (concave) is changed. One advantage of this adjustment

It is vital that you know, as accurately as you can, the size distribution of the raw material. The Sandvik CH cone crusher can be calibrated to achieve specific results, maximize productivity and minimize wear, but any calculation will be undermined without a solid understanding of what is going in to the crusher. Sampling is a vital part of the crushing process, to ensure that you know the size distribution of the

Fines (for example, 0–4 mm) should be screened out before the material is fed to the crusher as the fines may cause packing: this is a force overload and can be seen as adjustment ring movement.

Effect of Feed Rock Size Distribution on Crusher

17/03/2017  The effect of the undersize in the feed upon the capacity of the crusher depends upon several factors. If the crusher is a primary breaker, and the discharge opening is large, undersize will usually sift readily through the voids between the large pieces of material, and discharge quickly. The material must, of course, be free-flowing to behave in this manner. For such a condition, large quantities of undersize may materially add to the rated capacity of the crusher

The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1.
