The Blake Jaw Crusher, invented in 1858, was the first rock crusher to be patented and sold, featuring a key mechanical principle of toggle linkage. Different types of Blake crushers exist. These include single toggle and double toggle jaw crushers.
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 crusher machines are used in the mining and construction industry for crushing rocks and mineral ores to the appropriate sizes for direct application or further processing.
Each type of crusher has its own unique benefits and applications. For instance: Jaw Crushers: Ideal for heavy-duty primary crushing applications. Cone Crushers: Perfect for secondary and tertiary crushing with precise output. Impact …
A schematic diagram of the Blake jaw Crusher is shown in Fig. It has a fixed jaw and a movable jaw, which is pivoted at the top. The jaws are not set to form a V open at the top. The swinging jaw which reciprocates in a horizontal plane usually makes an angle of 20 to 30° with the fixed jaw. Jaw crusher diagram The jaws ar…
a jaw crusher. THEORY: Crushers are slow speed machines for coarse reduction of large quantities of solids. The main types are jaw crushers, gyratory crushers, smooth-roll crushers and toothed-roll crushers. There are two distinct types of jaw crushers, the Blake crushers and the dodge crusher. The Blake Jaw crusher is the commonly used crusher.
— Jaw crusher is a kind of size reduction machine that is wide utilized in mineral, aggregates and metallurgy fields. The interaction between jaw plates and material particles brings the inevitable and high wear to the jaw plates throughout the jaw crusher operation, that not only decreases the efficiency, however also will increase the price and also the energy consumption of the jaw …

The Blake features a double toggle jaw crusher drive mechanism which gives relatively smaller movement at the receiving end of the chamber generating a powerful crushing action for large rock pieces. A refinement on the crusher illustrated is the use of a curved jaw plate on the swing jaw which renders the crusher non-choking.

The recording instruments were first applied to a standard sized 10 by 7 in. Blake-type jaw crusher in the laboratory. Suficient tests were run on this with various combinations of setting, throw, speed, feed sizing, shapes of jaw plates, and other operating features, to establish the individual effect of each on the capacity.
crushers. The Blake crusher is considered the most common one, in which the swinging plate is pivoted at the top [2]. This crusher can be realized in two forms as double toggle and single toggle. Due to its simplicity, lower cost, and its higher efficiency, the single toggle jaw crusher is the most realized form in new applications.
What is a Blake Jaw Crusher? A Blake Jaw Crusher is a type of crusher that uses a swinging jaw to break rocks and minerals. This type of crusher was originally developed by Eli Whitney Blake in 1858, and it has been widely used in mining, construction, and the demolition industry ever since.

The Blake Crusher has a fixed jaw, and a swinging jaw pivoted at the top. On the other hand, the Dodge Crusher has a movable jaw that moves back and forth. Similarly, the Universal Crusher has a fixed jaw and a swinging jaw pivot that moves it across the crushing chamber. ... The primary function of jaw crushers is to crush materials into ...
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.
The Blake jaw crusher can handle larger materials than other types of jaw crushers. It is also known for its simple and rugged construction, low cost, and easy maintenance. The Blake jaw crusher is ideal for crushing hard …

In the Dodge crusher, shown in Fig. 5.5, the moving jaw is pivoted at the bottom. The minimum movement is, thus, at the bottom, and a more uniform product is obtained, although the crusher is less widely used because of its tendency to choke. The large opening at the top enables it to take very large feed and to effect a large size reduction.
Blake Jaw Crushers are generally used for primary crushing operations and are designed to handle large-sized materials. In contrast, Dodge Jaw Crushers are designed for …
