May 22, 2019 The crusher illustrated is a short-shaft suspended spindle type, meaning that the main shaft is suspended at the top and that the eccentric is mounted above the gear. The short-shaft design has superseded the long-shaft design in
The Nordberg short-shaft spider-suspended gyratory crusher with its characteristic shrink tie rods is shown in Fig. 27. It also features a built-in permanent lifting pin as part of the main shaft rather than using a removable eye bolt. The Traylor spider-suspended short-shaft gyratory crusher is shown in Fig. 28. It is also available as a hydrau-
The Cone crusher is operates via electric motor that drives a horizontal shaft amp pinion bevel gear further rotating a crown bevel gear mounted on an vertical eccentric sleeve creating a gyratory motion that affects the centre axle fitted inside the sleeve creating a compression crushing action between the Mantle amp concave section.
To optimize the crushing chamber of the gyratory crusher, the discrete element method DEM is used to explore the influence of the concave curve height, concave curve radius, eccentric angle, and mantle shaft speed on the performance of the crushing chamber in this paper, here, the DEM analysis model of iron ore particle is established based on the bonded particle model.
Dec 17, 2020 Dec 17, 2020 Another type of crushers often used in the primary crushing stage is gyratory crushers that have an oscillating shaft. The material is reduced in a crushing cavity, between an external fixed element, a bowl liner, and an internal moving element, mantle, mounted on the oscillating shaft assembly.
The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows 1. In a gyratory crusher including a lower frame, an upper frame mounted on the lower frame, a crusher mantle having a tapered internal bore extending through the mantle, and a shaft having a correspondingly tapered mantle supporting portion projecting through the

Gyratory crushers generally cost less than 1500 per hour to run, while Jaw crushers cost less than 200, including electricity Infomine, 2008. Rules of Thumb A 42-inch gyratory crusher produces approximately 2.4 tons per horsepower-hour 2.9 tkWh.
50-65MK- Gyratory Crusher Main Shaft. Our customer, The Three Gorges, who have 2 sets of 50-65MK- gyratory crushers. This model was put into operation in August 1999. After the operation, all units responded normally. And because of its large crushing ratio and high productivity, it has become the main equipment for artificial sand and ...
Jan 27, 2014 1. A gyratory crusher comprising a mainframe defining an internal crushing chamber a main shaft extending within the chamber and providing a mount for a mantle capable of gyroscopic precession within the crusher a hub having an internal volume in which a lower region of the main shaft is housed an eccentric assembly at least partially mounted within the
May 22, 2019 Metso 4265 Gyratory Crusher. May 22, 2019 April 6, 2021 itsd. A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. There are five types of crushers Jaw crusher, Gyratory crusher, Cone crusher, Impact crusher and Mineral sizers. A gyratory crusher is consisting of a concave surface and a conical head ...
Diagram of a gyratory crusher image 135-5-16 Gyratory Crushing Action. Designs of the breaking faces vary with manufacturer. As a result, the product size distribution varies. When the feed drops into the crusher, the mantle squeezes the rock against the concave surface.

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 below image shows a sectional view of a typical gyratory crusher.This type of machine is, by virtue of chronological priority, known as the standard gyratory crusher. Although it incorporates many refinements in design, it is fundamentally the same crusher that first bore the name of gyratory its crushing chamber is very much the same shape the motion is
following are either obsolete types of gyratory crushers, of which many are still in service, or are older designs with extremely limited capacity long-shaft spider-suspended gyratory crusher, fixed-shaft gy- ratory crusher, and short-shaft gearless gyratory crusher. The gyratory crusher, whether used as a primary or secondary.
