Crusher Product Gradation Charts

Apr 15, 2016  Crusher manufacturers publish grid charts, particle size cumulative distribution curves, and/or product size distribution tables to help predict the gradation of the crusher product. These charts, curves, and tables give the percentages passing or retained on standard size screens for each given setting of the crusher.

The pros and cons of cone crusher applications – Quarry

Apr 16, 2021  Feed gradation. Moisture content. A measure of the size reduction achieved for a particular crusher application is the reduction ratio. 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.

Tips to maximize crushing efficiency - Pit Quarry : Pit ...

May 13, 2019  Gradations of cone feed and crusher discharge must be monitored as a crushing/reduction performance indicator and as a liner wear indicator. This should be done at least once a month, and more often if required at the site. Daily inspections below the crusher should be made to ensure no bridging, plugging or foreign material are under the crusher.

Maximize your cone crusher productivity : Pit Quarry

Apr 28, 2017  An example of the effect that crusher setting has on the product gradation is as follows: If the target crusher setting is 3/8 in. (10 mm) but the setting is not checked and it wears open to 1/2 in. (13 mm), then the end result is a 15 percent decrease in the minus 3/8-in. (10 mm) material size.

As with other compression crushers, the cone crusher yields a somewhat elongated and slivery particle shape. This may be minimized, however, by "choke" feeding the crusher. This technique will also make the shape and size more uniform. One way to choke feed is with a surge hopper and a controlled belt-feed to the cone crusher (Figure 5-10).

Gyratory Crusher - an overview ScienceDirect Topics

The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the machine are ...
