A jaw crusher is a device that reduces the size of various solid materials in many applications, including underground mining and mobile crushing applications mainly using the compressive force of the two jaws, one of which is stationary and the other is moving. The jaw crushers moving jaw undergoes two main types of motion, one resulting from the eccentric shaft movement, and the second from the toggle. We provide a large number of solutions for customers in more than 160 countries/regions around the world, and are committed to creating the most suitable solutions for customers. We welcome your inquiry 7/24 hours.

The crushing is achieved by using compressive forces between two plates jaws to break the substrates. One plate is typically fixed in a V alignment while the other plate reciprocates resulting in the crushing action. The gap between the plates can be adjusted to accommodate different incoming sizes and the desired crushed output.

All jaw crushers reduce large sized rocks, ore, or other material by a compression action. A fixed jaw, mounted in a V-shaped alignment, is the stationary breaking surface, while a movable, swing jaw exerts force on the feed material by pushing it against the stationary plate.

Currently there are a number of solutions for crushing materials such as rock, gravel, coal, mineral ore and reclaimed concrete or asphalt. Some of these solutions are large, expensive, high capacity machines intended for continuous stationary use and permanent installation. These solutions fail to meet the needs of smaller-scale industries that require a small but sturdy and relatively inexpensive portable crusher that can be easily moved to different locations to quickly and reliably process smaller quantities of varied materials.

Machines designed primarily to crush hard materials often suffer from plugging when challenged to process softer materials such as reclaimed asphalt which, regardless of jaw material, can adhere to the crushing jaws as a sticky mass, particularly in warm weather. In either case, when such single-purpose machines eventually plug, they often require partial disassembly to clear the crushing chamber. As a consequence existing portable crushers are inherently limited in their ability to process a wide range of feed materials efficiently and at relatively low cost.

The path of motion of the moveable jaw relative to a fixed jaw can have either a positive or negative effect on jaw crusher machine operation, depending on the feed material. For example, the component of jaw movement perpendicular to the fixed jaw creates the compressive forces needed to break hard material such as rock and concrete. However, these compressive forces can also cause softer material such as reclaimed asphalt to adhere to the crusher jaws as a sticky mass.

U.S. Pat. No. 4,248,390 teaches a double-acting double-eccentric jaw crusher that completely eliminates vertical motion or tilting of the moveable jaw, thereby producing a fixed and uniform ratio of shear to compressive force over the entire crushing surface throughout the crushing stroke, and correspondingly uniform abrasive wear on the crushing surfaces. The crushing action is unaffected by the direction of driving shaft rotation. Although the design is effective for crushing hard materials, its motion is inflexible and does not provide the versatility to also handle softer materials.

The present invention advantageously fills the aforementioned deficiencies by providing a jaw crusher machine which has a crushing action easily adapted to break hard materials such as rock and concrete or crush softer material such as asphalt, which is resistant to plugging and easily cleared with minimal effort by the operator should plugging occur, and which minimizes jaw motions that abrasively wear the crushing surfaces or cause spit-back of feed material.

In accordance with another embodiment, the present invention may have first connecting rods connected at one of their ends to the eccentric and pivotally connected at their opposite ends to second connecting rods rigidly attached to the vertical jaw, the first connecting rods being pivotally supported at a point along their length by linear bearings that constrain said first rods to substantially horizontal reciprocating pivotal motion.

Accordingly several advantages of one or more aspects are as follows to provide a jaw crusher machine that does not greatly suffer from any of the problems or deficiencies associated with prior solutions, that operates more smoothly with less vibration, that is more economical to produce, easier to manufacture, easier to repair and more durable, and that is smaller and more lightweight than other solutions, thereby enabling the device to be more easily portable. Other advantages of one or more aspects will be apparent from a consideration of the drawings and ensuing description.

Analysis Of The Single Toggle Jaw Crusher Force. Today the most commonly used types of jaw crusher are the single toggle and the double toggle designs 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 jaw crushers and the gyratory crusher all employ a predominantly compressive force. Other coarse crushers Friable materials, such as coal, may be broken up without the application of large forces, and therefore less robust plant may be used.

Jan 04, 2019nbsp018332A jaw crusher is a compression-type of crusher. Material is reduced by squeezing the feed material between a moving piece of steel and a stationary piece. The setting or the space between those two pieces of steel controls the discharge size. The tighter the setting, the smaller the output size and the lower the throughput capacity.
