Blake Jaw Crusher: This type of jaw crusher is the most commonly used in primary crushing applications. It employs a movable jaw to exert pressure on the rock or ore material, forcing it to break ...
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.

Straight Jaw Plates: A shows a diagram of a standard type of Blake crusher with regular or straight jaw plates. This type of plate has been the standard from the time of its inception, emulating, in this respect, the straight concaves in the gyratory machine. And it will be noted that the theoretical action in this straight-plate ... ="Jaw Crusher Liner Plate Design & …
Jaw crushers find a wide application for brittle materials. For example, they are used for comminution of porous copper cake. ... Currently, the dimensions of the largest Blake-type jaw …
Blake's design, which utilized a toggle linkage construction, was known as the Blake Jaw Crusher. Blake's crusher was announced in 1857 and patented in 1858. Perhaps surprisingly, the same basic design is still in use today for rock crushers. In the years following the design of the Blake Jaw Crusher, another type of crusher was designed.
Blake jaw crushers, also as double toggle jaw crushers, are characterized by the position of the pivot of the swing jaw, which is located at the top of the machine. This design allows for a larger feed size and a higher …
A review on the design and operations challenges of a single toggle jaw crusher is presented. Strength and fracture toughness of the material to be crushed are intrinsic properties that determine ...
The Blake Crusher-The Swing Jaw market is primarily segmented by types (Single Toggle Jaw Crushers, Double Toggle Jaw Crushers), downstream industries and applications (Mining Operations, Smelting ...
Double Toggle – Blake Type or Overhead Pivot Movement. Double toggle movement jaw crushers like the Blake style (named for the inventor of the first successful mechanical jaw crusher, Eli Whitney Blake), have long been the …
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 ...
In conclusion, the Blake Jaw Crusher and the Dodge Jaw Crusher are two different types of crushers that are commonly used in the mining and construction industries. …
The larger opening at the top enables it to take very large feed and to effect a large size reduction. This crusher is usually made in smaller sizes than the Blake-Jaw Crusher due to high fluctuating stresses that are produced in the members of the machine. Jaw crushers occupy a very important position in the field of mineral processing.
This is because the Blake Jaw Crusher integrated a key mechanical principle – the toggle linkage – a concept students of mechanics are familiar with. ... are compression-type crushers that are typically found in secondary crushing stages but can be used as the primary crusher in certain applications. They handle medium hard to very hard ...
Blake jaw crusher: In the Blake or jaw crusher the moveable jaw is pivoted at top. The greatest amount of motion is at the bottom which means it has the little tendency to choke. Dodge jaw crusher ...
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. ... laying down the foundational work in various industrial …
The Jaw Crusher was first introduced by Eli Whitney Blake in 1858 as a double-toggle Jaw Crusher. Introduced in 1906, McLanahan's Universal Jaw Crusher was one of the first modern era overhead eccentric Jaw Crushers. ... The information below will determine the size Jaw Crusher for most applications: Maximum material lump, or largest size ...
The jaw crusher was invented by the American E•W•Blake (Blake). Since the first jaw crusher came out, it has a history of more than 140 years. In this process, its structure has been continuously improved. There are two basic models of jaw crusher, namely simple pendulum jaw crusher and compound pendulum jaw crusher.

A sectional view of a jaw crusher which incorporates the Blake double-toggle mechanism is shown below. The Blake crusher in common with all machines of the jaw family is built into a rectangular frame, at one end of …
Dodge and Universal. These are distinguished by the manner in which the movable jaw is moved in relation to the stationary jaw. In the Blake-type crusher, which is the most common type of jaw crusher, the movable jaw is pivoted at the top so that it has a fixed receiving area and a variable discharge opening.
The document describes the components, working principle, types, applications and features of a jaw crusher. It discusses the Dodge and Blake jaw crushers, which differ in the pivot point of the moving jaw. An experiment …
The initial breaking up of ore is done by one of two types of jaw crushers which are known as single toggle and blake jaw crushers. The central difference is their crushing procedures. Single-toggle jaw crushers are used for the simplicity of design, where the movable jaw moves at the top of the crusher.
