The Gyratory Crusher is made up of six main components, Base, Main frame and concave liners, Drive assembly, Mantle, Spider arm assembly, Oil system. The base is the section of the crusher that provides an entry point for the drive assembly and oil system. It also provides support for the working surface of the main frame and liners.

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.

A gyratory crusher is one of the main types of primary crushers in a . mine or ore processing plant.

Gyratory crusher. A gyratory crusher is similar in basic concept to a jaw crusher, consisting of a concave surface and a conical head with both the surfaces are typically lined with manganese steel liners. ... The movement is generated by an eccentric arrangement. The crushing action is caused by the closing of the gap between the …

In the first class the major action is compressive, whereas grinders combine shear and impact with compressive forces. Crushers. Jaw and gyratory crushers are heavy equipment and are not used extensively in the food industry. ... Jaw and gyratory crusher actions are illustrated in Fig. 11.1(a) and (b). Figure 11.1 Crushers: (a) jaw, (b) gyratory.

There is a breathing or agitating action of the material in the feed zone above the line XY, ... The method of controllingthe feed to a sparse fed gyratory crusher having an outwardly flaring head and an overhanging bowl, and a stroke of such frequency, amplitude and direction as to permit the particles undergoing crushing to fall freely away ...

Gyratory Crushers are heavy-duty machines run in open circuit (sometimes in conjunction with scalping screens or grizzlies). They handle dry run-of-mine feed material as large as 1 m. There are two main …

A gyratory crusher according to claim 1 in which the distance that the said lower edge of the cylindrical sleeve of the bushing is below the fulcrum point, is less than the distance between the top of the shaft and the fulcrum point, to thereby minimize lubricant pumping and pressurizing action by the portion of the shaft gyrating within the ...

The gyratory crushers crush to reduce the size by a maximum of about one-tenth its size. Usually, metallurgical operations require greater size reduction; hence, the …

A gyratory crusher includes a flexible dust seal having an outer edge attached to a cone head of the crusher and to an outer of a ball-bearing seal, an inner race of which is attached to a mounting arrangement for rotationally mounting an eccentric member about a crusher axis with a pair of taper bearings and for rotationally mounting the cone head about a …

So, if you are looking for a powerhouse machine that can crush larger materials more easily, a gyratory crusher is a much better choice. One of the key differences between these two types of crushers …

Gyratory crusher Jaw crusher or Jaw crusher is the better choice because of: 1-Jaw crusher can take larger size than gyratory & is better adopted to handle clayey & spongy rocks. 2-Gyartory crusher consume more power for the same feed as produces more new surfaces than jaw crusher. 3-Installation and housing costs will be more …
