Jaw Crushers. A jaw crusher applies pressure to material with a movable lever against an immovable wall. The force exerted in the crushing chamber is generated and maintained by a flywheel moving the swing jaw, while the stationary jaw provides the resistance. Between the two surfaces, heavy materials such as stone and ore are broken …
The opening of the primary crusher, for example, will affect the throughput of secondary crushing, and secondary crushing will, in turn, influence tertiary production and so on. How to check the opening of the jaw crusher Whenever a jaw crusher is off and at rest (stopped), it will remain in the open position at its open-side setting (OSS).

Large receiving opening per dollar of investment. Shape of receiving opening favourable for blocky feed. This, plus point 1, give the jaw a definite advantage over the gyratory, except in the very large sizes, for handling rock of massive formation. The jaw crusher is more easily adjusted, to compensate for wear of liners.
The working principle of jaw crushers is based on the reciprocating movement of the movable jaw that compresses and crushes the rock or ore between itself and the fixed jaw, as the material enters the zone …
A jaw crusher uses compressive force for breaking of particle. This mechanical pressure is achieved by the two jaws of the crusher of which one is fixed while the other reciprocates. ... For your …

Construction. The main difference between these two crushers lies in the construction of their crushing chamber. Blake Jaw Crushers have a single swing jaw while Dodge Jaw Crushers have double swing jaws. Crushing Action. Blake Jaw Crushers have a fixed jaw and a moving jaw that swings in an arc.
They are designed to crush large rocks into smaller pieces suitable for secondary crushing using either compression or shearing action. These versatile machines can be used in a wide range of applications ranging from 80 – 875 tons/hour depending on the model and settings. Model. PE-150×250~PE-1500×1800, PEX-150×750~PEX-300×1300.
As we introduced in a recent blog post about all the different types of crushing equipmentavailable, jaw crushers are sometimes also referred to as "rock breakers," which speaks to their brute force. They are almost exclusively used as primary crushers because they excel at breaking up some of the …
UJ210 offers a primary crushing solution fully assembled on a single trailer frame and mounted on a double axle bogie. We have equipped this unit with the reliable and highly productive CJ409 jaw crusher, to ensure outstanding efficiency and productivity. It also comes equipped with features to enhance your productivity ...
Jaw crusher units with extra-long, articulated crusher jaws prevent coarse material from blocking while moving all mounting elements of the crusher jaw from the wear area. A more even material flow may be affected if the transfer from the prescreen or the feeder trough is designed so material simply tilts into the crushing jaw.
Wesley J. Sherwood Jr., Crusher Feed Controller, age 22, was killed on December 15, 2011, when he fell into an operating jaw crusher. Sherwood was last seen standing on the viewing platform. He apparently climbed over the railing of the platform to access the vibratory feeder to clear jammed material close to the opening of the crushing …
Moreover, there has been an increasing interest in understanding the fragmentation process of blasting and assessment methods as well as with estimation models. ... The jaw crusher's closed side setting was 150mm. The crusher setting affects the product size and the capacity.
1.) Obtaining the size or surface area required for the use of the ore or material. 2.) Allowing ease of transportation and storage. 3.) Separating the different minerals contained within the ore and to release them from one …
2. The Role of Jaw Plates. At the heart of a jaw crusher are two jaw plates – one fixed and the other movable. These plates act as a funnel, guiding the material to be crushed into the space between them. As the movable jaw exerts a force on the rock, it presses it against the fixed jaw, gradually breaking it down into smaller pieces.
Pi tman is the main component of a jaw crusher that forms the moving part of the crusher. It functions as the link between the stationary and the moving jaw. The pitman is responsible for transferring the motion of the eccentric shaft to the rest of the crusher components, such as the toggle plate and the swing jaw.
Clean individual parts of jaw crusher. Replace lubrication oil, repair and adjust lubrication system and so on. A monthly repair is usually done half a month or once a month and is dependant on ...
Preventive maintenance is usually set up on a daily (8 hours), weekly (40 hours), monthly (200 hours), yearly (2,000 hours), and liner change schedule. Following the scheduled checks and inspections, adjustments are made and worn parts are replaced before a major crusher breakdown occurs. Preventive maintenance is a key component …

A jaw crusher is a machine that breaks down large rocks into smaller pieces of rock, gravel, or dust. It does this by placing two jaw plates perpendicular to each other and …
For example, a 32 x 54 sized jaw crusher will measure 32 inches from the movable to stationary jaw (when measured at the top i.e. the opening), and each jaw will have a 54-inch width. If a jaw crusher is rated by jaw plate size, a suitable rating maybe 600 x 400, which indicates a 600 mm by 400 mm jaw plate dimension.
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. The space at the bottom of the "V"-aligned jaw plates is the output gap that dictates the size of the crushed product from the jaw crusher.
