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

Construction, Working and Maintenance of Crushers for

Generally gyratory crushers, jaw crushers, high speed double roll crushers, low speed sizers, impactors and hammer mills are used as primary crushers. In the secondary and subsequent stages, the material is further reduced and refined for proper size and shape, mostly based on specifications. Most secondary crushers are cone crushers and horizontal shaft impacts. For coal, many times, rotary

New digital-enabled TSUV Gyratory Crusher

Unlike other gyratory crushers, which require workers to get in underneath the crusher to perform high-risk maintenance, the TS range allows service and maintenance to be carried out from above, increasing speed, safety and simplicity. Additionally, the 100+ tonne, fully-dressed main-shaft no longer needs to be guided into the eccentric assembly by hand. Now, the shaft aligns automatically

Crushers QueensMineDesignWiki

The maximum motion occurs at the top of the jaw and is created by an eccentric shaft. Due to the rubbing action of both the vertical and horizontal components of the jaw, the plate wear is accelerated and the power efficiency is lowered. This motion does give an advantage when handling sticky materials where a DT jaw crusher would not do well as its motion is perpendicular to the fixed plate

Gyratory crusher having dynamically adjustable stroke

The speed of the motor, the size ratio of the pulleys on the motor and the crusher, and the gearing of the eccentric element determine the speed at which the head gyrates, sometimes referred to as the "gyrational speed". The gyrational speed selected for each crusher depends on the particular application for which the crusher is to be used.

Crushing 101 Different types of crushers for distinctive

17/12/2020 In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of the crusher, while the other is an eccentric shaft that drives both toggle plates. The chewing movement, which causes

Difference Between Jaw Crusher and Gyratory Crusher JXSC

The belt and pulley are driven by an electric motor to move the movable jaw up and down through an eccentric shaft when jaw crusher working. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, which pushes the movable jaw plate to approach the fixed jaw plate. When the movable jaw down, the angle between the toggle plate and the moving jaw becomes
