There are three types of jaw crushers: Blake, Dodge, and Universal. They are classified according to the location of the pivot point of the swinging jaw. The most common type of jaw crusher today is the Blake crusher, patented by Eli Whitney Blake in 1858 (Weiss 1985). The Blake crusher pivots at the top and comes in two forms: the …
In the history of crushers, both chronologically, and by virtue of its standing in the field of heavy-duty crushing, the Blake jaw crusher stands first in the list. All of the large, heavy-duty primary crushers of the jaw type are built around the Blake principle which, for simplicity and brute strength, is unsurpassed by any […]
Jaw crushers are used as primary crushers, or the first step in the process of reducing rock. They crush primarily by using compression. The rock is dropped between two rigid pieces of metal, one of which then moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.
From Allis-Chalmers' Superior Primary and Secondary Crushers. ° Actual required depends on stone hardness, reduction ratio, and so on. If a 60-in. gyratory crusher is to process material from a …
This might be explained by the failure mechanisms of the particles in the crusher. In a jaw crusher, the FRAs are mainly produced by compression failure [22, 23] . It is believed that a change in ...
A material is crushed in a Blake jaw crusher such that the average size of particle is reduced from 50 to 10 ... A flow sheet for a typical closed circuit grinding process, in which a coarse crusher, an intermediate crusher, and a fine grinder are used, is shown in Fig. 5.3. In many plants, the product is continuously removed, either by ...
It was invented by Eli Whitney Blake in 1858. The Blake jaw crusher featured a double-toggle mechanism that allowed the swinging jaw to move alternately toward and away from the fixed jaw. This design provided a mechanical advantage, increasing the crushing capability. Blake's design laid the foundation for the modern jaw …
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 Jaw Crusher; Blake Jaw Crusher memiliki titik engsel jaw atau pivot di bagian atas, sedangkan bagian bawahnya yang bergerak maju mundur. Karena bagian bawah yang bergerak, maka lebar bukaan atau celah untuk keluarnya biji menjadi variatif. Pada saat bergerak maju, maka lebar bukaan adalah minimum disebut close side setting, dan …
This crusher is the finest of our lines of jaw crushers which we offer. Others 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.
® C Series™ jaw crushers are designed modular to save time and installation costs. They can be installed within a few days, minimizing on-site engineering and fabrication. The jaw crushers can be upgraded with …
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 ...
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 …
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. Comprising type of jaw crusher—the robust Single-toggle and the efficient Double-toggle—these hefty machines operate on the principle of compressing materials between …
The crushing process is a critical stage in converting huge stones, bulky materials into smaller, more manageable sizes for various applications in industries like mining and construction. ... There are mainly two types of jaw crushers: the single toggle and the double toggle (or Blake crusher). The single-toggle jaw crusher features a …
The Blake Jaw Crusher is known for its simple design, high efficiency, and ability to handle large-sized materials, making it a popular choice for primary crushing operations. The Dodge Jaw Crusher, on the other hand, is designed for medium-sized or smaller materials and is commonly used for secondary crushing operations. Despite their ...
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. On the overhead eccentric style Jaw Crusher, the moving swing jaw is suspended on the eccentric shaft with heavy-duty …

Many small process plants consisted of one crusher, either jaw or gyratory rock crushers, one elevator and one screen. Recrushing, if done, was taken care of by the same machine handling the primary break. The single crusher, when of the gyratory type, might be any size from the No. 2 (6″ opening) to the No. 6 with 12-in. opening.
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.
Moreover, the wear of the jaw liner profile lowers the crusher performance by affecting the shape and the overall size of the crushed particles [12, 13]. Warping and wear of the jaw plate cause a ...
