Uniform distribution of feed material around the cone crusher inlet is good practice. This allows production of a consistent product as well as efficient, reliable operation of the crusher. Choke feeding is important for ™b to maintain approximately 10–15% of material finer than the closed-side setting in the feed to assist the crushing action.

F = feed size distribution (mass) Equation (11.31) is the widely accepted model of crushers that is used to predict the size distribution of products in different types of crushers. While considering the above aspects of a model of crushers, it is important to remember that the size reduction process in commercial operations is continuous over long periods of time.

Feed size distribution is affected by material properties. Compression ratio depends on operating parameters and structural parameters of the cone crusher. As illustrated in Figure 1 , material properties, liner properties, operating parameters, and structural parameters are variables which affect sliding distance [ 19 – 21 ].

The size of the feed is a critical consideration that can affect virtually every aspect of the crushing process. Knowing the size distribution of your raw material will help you produce a more consistent final product while maximizing productivity and reducing undue wear to the crusher.

If the size distribution of particles from a crushing or grinding operation does not approximate a straight line, it suggests that there may have been a problem with the data collection, or there is something unusual happening in the comminution process. The size modulus is a measure of how coarse the size distribution is, and the distribution

The second effect of blasting, which is “unseen”, is the crack generation that occurs within fragments.

It’s hard to overstate the importance of feed size in a cone crusher. 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.

Feed should always be well graded with no gaps in the size distribution, which generally means an even distribution of different-sized feed material up to the defined maximum size. 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.
