Jaw crushers are used as primary crushers in a mine or ore processing plant or the first step in the process of reducing rock. They follow "crush using compression" mechanism.
This is because the Blake Jaw Crusher integrated a key mechanical principle – the toggle linkage – a concept students of mechanics are familiar with. In 1881, Philetus W. Gates received a U.S. patent for his device featuring the basic ideas of today's gyratory crushers. In 1883 Mr. Blake challenged Mr. Gates to crush 9 cubic yards of ...
Jaw crusher is used in stone mining, metallurgy industry, building material, highway, railway, and chemical industry. Suitable for crushing maximum, medium and minimum stones, it is primarily used to crush different types of mining stone and the largest compression resistance of the material to be crushed is 360 MPa.
Crusher definition: Crushers are slow-speed machines employed for the coarse reduction of large quantities of solids. Jaw crushers, Gyratory crushers, and Smooth-roll crushers are the main types of crushers. They operate or are used by compression and can break large lumps of hard materials. They find applications in the rockery and mining industries.
Jaw crushers include Superior, Type "B" Blake, Fine-Reduction, and Dodge — sizes, 4 by 6 to 84 by 66 inches. A reciprocating machine, the crushes material in a straight line between jaws — without grinding or rubbing surfaces. ... The pitman in any jaw crusher is essentially a tension member. However, because it also has a vertical ...
The jaw crusher is one of the most admired and most sought after equipment from the house of Propel Industries. For the benefit of newcomers in the industry, here is an explainer of the various components of the Jaw crusher. ... apart from serving as a safety mechanism for the entire jaw. The piece of non-crushable material …
The original double toggle jaw crusher was designed by Eli Whitney Blake in the USA in 1857 . 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. ... The single toggle jaw crusher mechanism can be modelled as a planar 4R mechanism, as …
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 ...
The actuating mechanism consists of the eccentric-shaft (also supported in bearings in the sides of the frame), the pitman, and the pair of toggles, which span from swing jaw to pit-man, and from pitman to rear end of the frame.
DOUBLE-TOGGLE JAW CRUSHER. The double-toggle mechanism, patented in 1858 by Mr. E. W. Blake, remains unrivalled for all units of exceptional power and size. Fig. 1 is a cross section of an early Blake crusher. The power was applied to an eccentric shaft rotated in fixed bearings situated close to the centre of a heavy cast-iron …
A jaw crusher is an indispensable tool in the mining and construction industries, known for its power to fragment hard materials such as rock and minerals. ... Comparing this dynamic to the Double-toggle, or Blake crusher, its diagram depicts a more complex motion but provides a consistent crushing cycle. ... Acting as a safety …
A jaw crusher operates by the movement of a movable jaw in relation to a fixed one to crush large rocks into smaller pieces. It does this by using a spinning shaft that makes the movable jaw move back and forth.
No discussion of primary crusher selection would be complete without a comparison of the two leading types: the standard gyratory crusher and the Blake jaw crusher. Although their fields of application overlap to a considerable degree (at least in the realm of primary crushing) there is no real conflict between these two machines; one …
These are bolts that have a known shear strength. If something that the crusher cannot crush accidentally gets into the crushing chamber these bolts will shear off when the Jaw hits the unbreakable object. This will prevent damage to the rest of the crusher. Unlike the gyratory crusher the main lubrication used on Jaw crushers is …
Jaw crushers are mainly used as primary crushers to produce material that can be transported by belt conveyors to the next crushing stages. The crushing process takes …
The motion of the swing jaw in a Blake crusher is predominantly vertical, which provides a compression action on the material. This vertical movement of the movable jaw plate is more efficient at reducing large, hard materials into smaller pieces, offering a higher reduction ratio and better uniformity of the product size.

Double toggle jaw crushers are the classic style of jaw crushers. They're also popularly known as the "Blake type" because of their similar mechanism to the original jaw crusher by Eli Whitney Blake.
In a jaw crusher, the material is crushed between two plates: a static plate and a moving plate. Compression is applied by the moving plate, and the material becomes crushed. The size reduction obtained by a jaw crusher is form conditioned crushing due to the nature of the machine. There are two main types of jaw crushers, single toggle and ...
