Gyratory and Cone Crusher - ScienceDirect

01-01-2016  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 ...

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 ...

Primary Crusher - an overview ScienceDirect Topics

The gyratory crusher has capacities starting from 1200 to above 5000 t/h. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Therefore, primary gyratories require quite a massive foundation. The cone crusher is a modified gyratory crusher.

Gyratory Crusher - an overview ScienceDirect

Gyratory crushers were invented by Charles Brown in 1877 and developed by Gates around 1881 and were referred to as a Gates crusher [1]. The smaller form is described as a cone crusher. The larger crushers are normally known as primary crushers as they are designed to receive run-on-mine (ROM) rocks directly from the mines.

crusher mantle drawings - vierenmetzorg.nl

Gyratory crushers are frequently used in the primary crushing stage and a little less often in in the secondary stage. Gyratory crushers have an oscillating shaft. The material is reduced in a crushing cavity, between an external fixed element (bowl liner) and an internal moving element (mantle) mounted on the oscillating shaft assembly.

GYRATORY CRUSHER WITH EXTERNAL DYNAMIC

Gyratory crushers are sometimes provided with internal balance weights to counterbalance forces generated by the gyratory movement of the head about a central vertical axis through the upper frame. Examples of such crushers are shown in U.S. Pat. Nos. 1,796,413 of 1931; 3,118,623 of 1964; and 3,454,230 of 1969. Not all gyratory crushers, and in ...

Declining Ore Grades Challenge Primary

Primary gyratory crushers (PGs) reduce ore from the pit to a consistent, manageable size. While most agree that PG design has changed very little in the last 20 to 30 years, thoughts surrounding PG installation have. Much of that thinking has to do with declining ore grades. Many mines have to process more ore to retrieve the same amount of metals.

Cone Crusher - an overview ScienceDirect Topics

Maintenance of the wear components in both gyratory and cone crushers is one of the major operating costs. Wear monitoring is possible using a Faro Arm (Figure 6.10), which is a portable coordinate measurement machine.Ultrasonic profiling is also used. A more advanced system using a laser scanner tool to profile the mantle and concave produces a 3D image of the crushing chamber (Erikson, 2014).
