The crusher model takes the fragmentation behaviour of the rock and feed size distribution into consideration. Moreover, chamber and machine geometry, together with machine parameters such as closed side setting, stroke and eccentric speed, is accounted for. On
The capacity of the crusher is dependent on the feed size of the material, strength of the feed and the filling of the crusher chamber. Coarse feed gives low capacity and vice versa. The crushing of the material is not affecting the shape of the grain size distribution curve that much, in fact mainly the coarsest material is being crushed, the ...
a maximum feed size that will enter the crusher without bridging and material finer than the crushers closed side setting removed. The capacities may vary depending on the feeding method and on feed characteristics such as gradation, bulk density, moisture, clay content and crushability.

the crusher and some material falls through and out. A certain amount of fresh feed is also taken in. This is illustrated in Figure 5.3. Let us now describe this behavior quantitatively. It is best to work with a discrete size distribution. So define pi F fraction of the feed in size class i, pi fraction of the product in size
Figure 21 Plot showing percentage of rock in feed size distribution from gyratory crusher passing sizes from 10 mm to 90 mm. 46 Figure 22 Plot showing data points of percentage of rock bigger than 50 mm with chaging gap size with curve fitted to data points by Gnuplot. 47
In this paper we develop a performance model for impact crushers. The product size distribution is obtained as a function of the crushers rotor radius and angular velocity, the feed rate and ...
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 feed.
The feed size to a secondary crusher is typically in the range of 50 mm to 250 mm up to 300 mm. If the capacity is higher, the acceptable feed size gets larger. After crushing, the product is in the range of 0-60 mm 75 mm diameter.
6 Construction, Working and Maintenance of Crushers for Crushing Bulk Materials www.practicalmaintenance.net shown in above figure, a closed circuit crushing system is a means of controlling product top size by screening the product and then returning oversize material to the feed
Apr 28, 2017 Typical reasons for adjustment ring movement or excessive power draw are tramp events, poor feed distribution, segregation of the feed, too many fines in the feed, high-moisture content, wrong mantle and bowl liner being used or simply trying to operate at an unrealistically small closed-side setting. 9. Monitor and maintain a proper crusher speed.

As a result, the product size distribution varies. When the feed drops into the crusher, the mantle squeezes the rock against the concave surface. When the mantle moves away and the rock drops down further and subject to additional crushing during the next cycle . Material exits the crusher through the open side setting.

Oct 22, 2015 By far the greater number of crusher applications involve feeds which are either graded a mixture of large, medium, and small particles, or sized to a top dimension well within the effective receiving-opening dimension of the crusher. Primary crusher feeds usually fall under the graded category, and reduction crusher feeds under the sized. Graded feeds may or may not have the
