The pros and cons of cone crusher applications

 · A cone crusher in a secondary crushing application will typically work with a 3.5:1 to 5:1 reduction ratio. Tertiary cone crusher configurations typically work with a reduction ratio of 2.5:1 to 4:1. The reduction ratio is defined as the ratio of the feed size for which 80 per cent will pass (F80), divided by the product size for which 80 per cent will pass (P80).

Chemical Engineering Stop: Rittinger''s and Kick''s laws

Different machine layouts can be compared with each other and evaluated at the design stage, By using the presented analytical model it is possible to optimize a single crushing stage if the incoming …

What affects cone crusher performance? — SRP

These are the two main causes of sub-optimal crushing performance, but losses in the reduction ratio can also be caused by selecting the wrong mantle or by having a poor chamber profile or design. Surprisingly, selecting the wrong alloy has no effect when it comes to the reduction ratio (although this will affect the life of wearable parts in your crusher).

4 Size reduction

d1/d2 is known as the size reduction ratio (RR) and is used to evaluate the relative performance of different types of equipment. Coarse grinding has RRs below 8:1, whereas in fine grinding, ratios can exceed 100:1 (Brennan et al., 1990). 2. Rittinger''s law states that

Volume of Cone

The volume of a cone is equal to one-third of the product area of circular base and height. Learn to derive its formula for a regular cone and see some solved examples at BYJU''S. The volume of a cone defines the space or the capacity of the cone. A cone is a three-dimensional geometric shape having a circular base that tapers from a flat base to a point called apex or vertex.

Tips to maximize crushing efficiency

 · Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent.
