Jaw Crusher. A. Gupta, D.S. Yan, in Mineral Processing Design and Operation, 2006. 4.1.2 Jaw crusher circuits. Primary jaw crushers typically operate in open circuit under dry conditions. Depending on the size reduction required, the primary jaw crushers are followed by secondary and tertiary crushing.
The impact crusher (typically PE series) is widely used and of high production efficiency and good safety performance. The finished product is of cube shape and the tension force and crack is avoided. Compared with hammer crusher, the impact crusher is able to fully utilize the high-speed impact energy of entire rotor.

6.2.3 Roll crusher circuit design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size. Both open and closed circuit crushing is employed.
Fig. 3 illustrates the operating principle and the main components of a cone crusher. A cone crusher basically comprises two bell-shaped manganese crushing liners placed inside each other. The concave is attached to the crusher frame and the mantle to the eccentric main shaft which is swaying around the geometric center point at the …

In addition, the performance of indus- trial jaw crushers was analyzed using the proposed equation in combination with that of Bond (1961) for calculating the energy requirement in size reduction.
pit and is in open circuit, with the crusher product being conveyed to the plant. In the plant this material is fed into the cone crusher, which is in closed circuit with a screen which takes the product from this crusher. The product from this circuit is the feed to the mill circuit: The total solid feed to the primary crusher is 1200 t/hr.
The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. It …
