Effect of Feed Rock Size Distribution on Crusher Performance

If the ore feed to any gyratory or jaw crusher consisted entirely of large cubes or spheres of a size that would just barely enter the crushing chamber, the crusher could not be expected to produce anything like its normal rated capacity because the upper part of the crusher

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. In actual practice

And the distribution of sizes in the product is completely determined from the size distribution in the feed and a knowledge of the classification and breakage functions. The classification function is usually of the form shown in Figure 5.4. d1 and d2 are parameters that are characteristic of the crusher. They are determined primarily by the setting of the crusher.

7/4/2020· 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. There are

4/1/2019· Uniform distribution of feed material around the cone crusher inlet is a good practice. This allows production of a consistent product, as well as efficient, reliable operation of the crusher. Choke-feeding is important for cone crushers because it maintains a good particle shape by facilitating an inter-particle crushing action. Trickle feeding is not the best option because it increases the

Comminution Wikipedia

The most common machines for the comminution of coarse feed material (primary crushers) are the jaw crusher (1m > P 80 > 100 mm), cone crusher (P 80 > 20 mm) and hammer crusher. Primary crusher product in intermediate feed particle size ranges (100mm > P80 > 20mm) can be ground in autogenous (AG) or semi-autogenous (SAG) mills depending on feed properties and application
