Double Toggle Jaw Crusher Working Principle

Home > Encyclopedia > Double Toggle Jaw Crusher Working Principle. Double Toggle Jaw Crusher Working Principle . The moving jaw is freely suspended from a shaft at its top edge and the jaw movement is transmitted through toggles near the lower edge. Maximum crushing force is applied at the inlet to the crushing chamber where the largest particles are found. The moving jaw is suspended

The Working Principle of Double Toggle Jaw Crusher

Principle of double toggle jaw crusher. Moving jaw hang directly on the eccentric shaft at the top, as a crank and connecting rod, directly driven by the eccentric shaft eccentric, the bottom of the moving jaw hinge thrust plate supported on the posterior wall of the rack. When the eccentric shaft rotates, moving jaw points on the trajectory is carried by some circular lines (radius equal to eccentricity), downward

Difference Between Single & Double Toggle Jaw

A double toggle jaw crusher is much larger, heavier, more moving parts and lower throughput than modern single toggle jaw crushers. The lower throughput statement is a bit misleading because it’s partially attributed to the type of bearings they have versus modern crushers, so if one was to upgrade the bearings, throughput could be closer to that of a modern jaw. Anyway, double toggle jaw

Jaw Crusher: Range, Working Principle, Application

A jaw or toggle crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it is small enough to escape from the bottom opening. The movement of the jaw can be quite small, since complete crushing

Jaw Crusher JXSC Machine

【What’s a jaw crusher?】A jaw crusher is a compression type crusher, usually used as a primary crusher set at the very front of the ore or rock crushing plant to reduce hard rock size. Jaw rock crusher commonly in double-toggle jaw crusher, composed of a fixed jaw and moving jaw, the discharging stone particle size can be controlled by changing the discharge port. Owing to its high crushing capacity and hard material efficiency, jaw

Jaw Crusher ScienceDirect

01/01/2016 The mechanism of crushing is either by applying impact force, pressure or a combination of both. The jaw crusher is primarily a compression crusher, while the others operate primarily by the application of impact. 4.2. Design of Jaw Crushers. Jaw crushers are designed to impart an impact on a rock particle placed between a fixed and a moving plate (jaw). The faces of the plates are made of

Crushers an overview ScienceDirect Topics

A double toggle crusher has, basically, 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 moving jaw has a pure reciprocating motion toward the fixed jaw. The crushing force is doubled compared to single toggle crushers and it can crush very hard ores. The jaw crusher is reliable and robust and therefore quite popular in primary crushing plants. The capacity of jaw

how a jaw crusher works and what it is used for

A Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw, mounted in a "V" alignment is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the stationary plate. The space at the bottom of the "V" aligned jaw plates is the crusher product size gap, or the size of the crushed product from the jaw crusher. The rock remains

Analysis of the Single Toggle Jaw Crusher Force

The motion of the swing jaw in a double toggle crusher is such that it applies an almost purely compressive force upon the material being crushed. This minimizes wear on the crushing surfaces of the jaws and makes the double toggle jaw crusher suitable for crushing highly abrasive and very hard materials. Even today, the Blake design, with some comparatively minor improvements, can still be

01/01/2016 The Blake crushers are single or double toggle drives. The function of the toggle(s) is to move the pivoted jaw. The retrieving action of the jaw from its furthest end of travel is by springs for small crushers or by a pitman for larger crushers. As the reciprocating action removes the moving jaw away from the fixed jaw the broken rock particles slip down, but are again caught at the next movement of the swinging jaw
