  • 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 th

  • Gyratory Crusher an overview ScienceDirect Topics

    Compared to the cone type crusher, a gyratory crusher has a crushing chamber designed to accept feed material of a relatively large size in relation to the mantle diameter. The primary gyratory crusher offers high capacity thanks to its generously dimensioned circular discharge opening (which provides a much larger area than that of the jaw crusher) and the continuous operation principle (while the reciprocating motion of the jaw crusher

    ratory crusher, and short-shaft gearless gyratory crusher. The gyratory crusher, whether used as a primary or secondary. is essentially a gravity-type machine. Material flows vertically from top to bottom. It receives a large coarse feed, usually run-of-mine, and its product normally requires additional crushing before produc- ing the final product. The gyratory crusher is a pressure crushing

  • Gyratory Crushers Mineral Processing & Metallurgy

    Essentially, the gyratory crusher consists of a heavy cast-iron, or steel, frame which includes in its lower part an actuating mechanism (eccentric and driving gears), and in its upper part a cone-shaped crushing chamber, lined with wear-resisting plates (concaves). Spanning the crushing chamber across its top is a steady-rest (spider), containing a machined journal which fixes the position of the upper end of the

The primary gyratory crusher offers high capacity thanks to its generously dimensioned circular discharge opening (which provides a much larger area than that of the jaw crusher) and the continuous operation principle (while the reciprocating motion of the jaw crusher produces a batch crushing action). The gyratory

  • Gyratory and Cone Crusher ScienceDirect

    01/01/2016· Gyratory Crusher Operation. Most crushing operations are performed under dry conditions. Water is only used occasionally as a lubricant to wash or flush the fines and sticking material on crusher surfaces. Gyratory crushers can accept 8–10% moisture in operation, but the fine content should be preferably less than 10%. The crushing action in gyratory crushers is regarded as rings or

  • Gyratory VS Jaw Crushers: Advantages & Disadvantages

    28/02/2016· Some rocks of massive formation may contain parallel cleavage planes in certain sections of the deposit. Such material will slab in the crusher just the same as those rocks which were formed in definite layers, or beds. The gyratory crusher by virtue of its annular discharge opening is an effective slab breaker. This faculty, coupled with the fact that its receiving openings are especially well suited for admitting slabby feed, give it a very definite advantage over the jaw crusher

    23/12/2015· Typical numbers are for liner and mantles to have a useful wear-life of almost 2,000,000 tonne on abrasive taconite and 9,000,000 tonnes on porphyry copper ores. Dependability and long service life are landmarks of good primary crusher design of up to 30 yrs. The selection of the primary crusher must consider best-in-breed maintenance services as the whole mine’s production goes

  • Liner wear and performance investigation of primary

    The research was aimed at understanding gyratory crusher liner wear in the overall context of the crushing process. Wear measurements were taken for in-service crushers during the research period using a novel laser profile measurement device. Data from the wear measurements was correlated with crusher production information such as current draw and throughput. This work resulted in enhanced knowledge of liner wear and its link to crusher

    Above figure shows sectional view of a typical gyratory crusher. Essentially, a gyratory crusher consists of a heavy cast-iron, or steel, shell/frame which includes in its lower part an actuating mechanism (eccentric and driving gears), and in its upper part a cone shaped crushing chamber, lined with wear resisting plates (concaves). Construction detail and working of the crusher is as under

  • Working Principle of Crushers

    17/02/2016· The gyratory crusher is used as a primary and secondary stage crusher. The cone crusher is used as a secondary, tertiary, and quaternary crusher. The action of a typical gyratory-type crusher is illustrated above. In gyratory crushers the crushing process comprises reduction by compression between two confining faces and a subsequent freeing movement during which the

  • Crushers QueensMineDesignWiki

    The gyratory crusher consists of a wide opening that has a conical shaped mid section leading down to a narrow bottom. Using the center element to rotate and gyrate about its fulcrum, the rock is broken due to the motion of the centerpiece in relation to the outer shell (advance and retreat). These types of crusher have capacities from 350 to 10,000 MTPH (mega tons per hour) (Mular et al, 2002). The advantages and disadvantages of a gyratory crusher
