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 …
As ideal primary or secondary crusher equipment, jaw crushers with different types are often used in various industries. Depending on different ways of moving, jaw crushers are divided into four types: Blake jaw crusher, Dodge jaw crusher, PE universal jaw crusher and mobile jaw crusher.
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.

How To Use A Jaw Crusher? If you want to use a jaw crusher to crush rocks or other materials, there are a few key things that you should keep in mind. First, you will need to carefully select the jaw plates so that they can effectively …
The lifespan of jaw plates can vary depending on a variety of factors, including the material being crushed, the application, the crusher model, and the quality of the jaw plates themselves. Generally, jaw plates made of higher-quality materials like manganese steel or tungsten carbide will have a longer lifespan than those made of lower ...
This is because the Blake Jaw Crusher integrated a key mechanical principle – the toggle linkage – a concept students of mechanics are familiar with. ... 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 ...
This is because the Blake Jaw Crusher integrated a key mechanical principle – the toggle linkage – a concept students of mechanics are familiar with. ... The right primary crusher for an application depends on several factors: Material to be crushed. Feed size. Desired product size. Capacity required. Compressive strength of the feed.
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.
The Stag jaw crusher, shown in Fig. 5.4, has a fixed jaw and a moving jaw pivoted at the top with the crushing faces formed of manganese steel. Because the maximum movement of the jaw is at the bottom, there is little tendency for the machine to clog, though some uncrushed material may fall through and have to be returned to the crusher.
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 …
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 standard used for crushing hard and abrasive rocks, as well as sticky feeds. These jaw crushers have high energy efficiency.
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 …
Unlike the Blake Jaw Crusher, the Dodge Jaw Crusher has a movable jaw that moves back and forth like a pendulum, while the fixed jaw remains in a stationary position. As the material is fed into the crushing chamber, it is crushed by the movement of the movable jaw against the fixed jaw.
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 …
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 ...
BLAKE JAW CRUSHER It is used for reducing run-of-mine ore or coal to a size small enough to be taken by the next crusher in the series during the first stage of crushing. APPLICATIONS TECHNICAL SPECIFICATIONS 1. Size: 300 mm dia. X 200 mm dia. 2. Motor: 2 nos. 1 hp / (415-440) v / 3 Ph / 50cycles / TEFC (Totally
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 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. LOWER CRUSHING COSTS
Eli Whitney Blake invented the first successful mechanical rock breaker – the Blake jaw crusher patented in 1858. In 1881, Philters W Gates was granted a patent on a machine that included in its design all of ... The benefit to the crusher application …
SINGLE TOGGLE JAW CRUSHER: DOUBLE TOGGLE JAW CRUSHER: Uses one toggle plate. Uses two toggle plates. Less expensive: More expensive: Lesser number of parts: More number of parts: Higher throughput: Lower throughput: Crushing stroke has vertical movement along with to and fro motion: To and fro swinging door motion of the crushing …
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 standard for crushing hard ...
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.
This step-by-step reduction ensures that the final product meets the specific requirements of the intended application, be it construction, manufacturing, or mineral processing. ... There are mainly two types of jaw …
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.
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 grease instead ...
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.

However, Eli Whitney developed and sold the first crusher in 1858; it was known as Blake Jaw Crusher. Blake came up with this equipment by integrating a critical mechanical principle, the toggle linkage, to put down a rock surface on the roads of Westville town. ...
