  • Gyratory Crusher an overview ScienceDirect Topics

    Gyratory crushers work on the same principle as cone crushers (Figure 4.4(c)). These have a gyratory motion driven by an eccentric wheel. These machines will not accept materials with a large particle size and therefore only jaw or impact crushers should be considered as primary crushers. Gyratory and cone crushers are likely to become jammed by fragments that are too large or too heavy. It is

  • 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

  • Gyratory VS Jaw Crushers: Advantages & Disadvantages

    19/3/2017· The jaw crusher, because of its box-frame construction, and simple toggle mechanism, is especially well adapted to extra heavy design for the crushing of extremely tough materials: in this respect it holds some advantage over the gyratory type, because the extra strength necessary for such work can be built into it at less cost than is required for the gyratory with its more complex shell

    liberate impurities Jaw and gyratory crushers are the most common types of primary compression crushers. Each applies a compressive force to rock particles as they come in contact with the crushing surfaces. The force is applied slowly (in comparison to impact machines) resulting in abrasion and cleavage fracture. Impact crushers apply a high-speed impact force to rock particles using

    The objectives of particle size reduction are to facilitate handling, liberate mineral from gangue and to increase the surface area of mineral particles for exposure to chemical processes. The most common types of crushers fall into two groups: Jaw Crushers which have a reciprocating jaw crushing rock against a fixed jaw, and rotating crushers such as Gyratory and Cone Crushers. Crushing may

    In a gyratory crusher, a round moving crushing surface is located within a round hard shell which serves as the stationary surface (figure 3). The crushing action is created by the closing the gap between the hard crushing surface attached to the spindle and the concave liners (fixed) mounted on the main frame of the crusher. The gap is opened and closed by an eccentric drive on the bottom of
