Sieve Analysis is a test method used in civil engineering to analyze the particle size distribution of a soil by passing the soil sample through a series of sieves with size of mesh opening decreasing from top to bottom and weighing the material that is retained in each sieve. Here, grade refers to the size of the particles.

General Description. This model is used to simulate a general crusher. This is a simple model for a crusher. It requires the user to specify one of three methods of defining the discharge product: a discharge partition curve for the crusher product, a selection / breakage function or using test data to define a product size distribution for a given feed size distribution.

An example size distribution from a set of test sieves is shown below in Table 1. Size fractions are normally identified by their top size and bottom size, as shown in column (A). The last size fraction, in this case -45 micrometers, is material that goes through all of the screens and is collected in the bottom pan (the final pan product).

This curve shows approximately 29 percent of minus 3/4″ in the material as it comes from the crusher, or 29 tons of fines in each 100 tons of crusher output. But, for the circulating load, we are only interested in that fraction of the crusher output which will pass the 3/4″ screen, which is 85 tons.

It is vital that you know, as accurately as you can, the size distribution of the raw material. The 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.
