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. This is a substantial decrease in productivity.

Crushing 101 – Different types of crushers for distinctive needs

In these cases, also cone crushers can carry out the first stage of the crushing process. The cone crushers are equipped with a hydraulic setting adjustment system, which adjusts closed side setting and thus affects product gradation. Depending on the cone crusher, the setting can be adjusted in two ways.

Also notice that the per cent minus 13 mm and 9.5 mm in the crushers' discharge is about 10% higher even though the crushers are operating at close to the same close side setting. One of the main reasons for the differential in this test is the larger eccentric throw in the fixed set unit.

Below the surface: Setting up an underground primary jaw crusher

In either case, the top size of the material ends up typically in the range of 200mm to 350mm, which is good for belt conveyors and fits into most secondary crushers without causing process risks. To achieve this top size, the crusher setting is 200mm or below, depending on the rock characteristics.

Open or Closed Circuit Crushing

Also assume that the material is such that the crusher selected will crush it to a size, 70% of which will pass a square-opening test sieve equivalent to the close-side crusher setting. This can be determined either from tests made on the material, or from the table of approximate values presented in a foregoing section.

Crusher

An eccentric shaft rotated by a gear and pinion produces the oscillating movement of the main shaft. The eccentricity causes the cone head to oscillate between the open side setting (o.s.s.) and closed side setting (c.s.s.). In addition to c.s.s., eccentricity is one of the major factors that determine the capacity of gyratory and cone crushers.

Cone crusher basics in 4 minutes

As the feed is crushed, it falls and exits the crusher through the space at the bottom. The eccentric gyration of the mantle means that at any moment this space is narrowest at one point, and widest at the opposite point. The widest distance is known as the open side setting (OSS) and the narrowest, the closed side setting (CSS).

Jaw crushers find a wide application for brittle materials. For example, they are used for comminution of porous copper cake. A Fritsch jaw crusher with maximal feed size 95 mm, final fineness (depends on gap setting) 0.3–15 mm, and maximal continuous throughput 250 Kg/h is shown in Fig. 2.8.

A fundamental model of an industrial-scale jaw crusher

The throughput of a jaw crusher ranges between 30 and 1200 tph (Wills and Napier-Munn, 2015). Jaw crushers have been modelled previously; in 1953, Gauldie conducted a performance study of the jaw crusher, including a capacity model that handles varying speeds and closed side setting (CSS) (Gauldie, 1953).

Crusher gap measurement

The C-Gap works by placing selected high-density rubber hollow bulbs into the crusher mantle. When the bulb is squeezed between the fixed and moving plates, the air pressure in the hose increases, then, by correlating the air pressure through manual calibration, the CSS is measured between 7 mm and 220 mm with an accuracy of 1 mm.
