  • 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

    Concave alloy selection We use the hardest alloy that will withstand the impacts of a specific gyratory application. This depends on the compressive strength, toughness, and friability of the material being crushed. For example, crushing some tough materials demands work-hardening manganese steel. But the same liners used for an abrasive, friable ore may wear quickly because there are

  • Gyratory and Cone Crusher ScienceDirect

    1/1/2016· Primary crushers are solidly built to receive large lumps of rock directly from the mines and designed for large tonnage throughputs. Basically, gyratory crushers consist of a fixed solid conical shell or bowl (also called concaves) and a solid cone within the bowl called a breaking head (Figure 5.1).The breaking head is fixed to a central spindle, which is hydraulically suspended or

    Hello everybody, Wondering if somebody could help me. I have experienced many problems due abnormal power draw behavior of the electric motor in a primary gyratory crusher in iron ore crushing,especially when the service life of the first row concave comes to an end. I suspect that the current ec

The gyratory crusher has been built in three types known respec- tively as the suspended-spindle, the supported-spindle and the fixed- spindle type. The second type, with the hydraulic piston as the sup porting member, is the most used. These three types all have some common features, the principal ones

    24/7/2015· As the Crusher Concave Liners and Mantle Wear out there is a period when the crusher won’t be as efficient as it could be. This can be a very frustrating period for the operators. Since the throughput drops and operators have to work harder, usually doing the same thing over and over again. Unfortunately to get the most from the equipment requires that there is one hundred percent wear on

    Why is a Crusher Concave Profile so important to its production rate and product sizing.

  • Crusher an overview ScienceDirect Topics

    These crushers are designed so that the head to depth ratio is larger than the standard gyratory crusher and the cone angles are much flatter and the slope of the mantle and the concaves are parallel to each other. The flatter cone angles helps to retain the particles longer between the crushing surfaces and therefore produce much finer particles. To prevent damage to the crushing surfaces
