PEW Jaw Crusher

PEW Jaw Crusher

It is newly designed and improved by our experts on basis of their more than 20 years’ crusher manufacturing and design experience. The unique design concept makes this series crusher achieve perfect combination between crushing efficiency and operating cost. Meanwhile, it has a wide range of application, particularly is suitable for crushing hard rock, such as basalt, river pebbles.

Application Of PEW Jaw Crusher

Mainly apply to broken or finely (also used in coarse crushing) hardness of materials.Its characteristic is only a bracket, moving jaw ellipse trajectory for the downward sloping, move the upper jaw horizontal stroke is big, can meet the required amount of compression crushing ore.When moving jaw moves downward, have promote role.In the case of conditions quite, productivity is around 30% higher than simple swing crusher.However, because of the moving jaw vertical stroke, increases the jaw plate wear and products through crushing phenomenon.

How To Choose Jaw Crushes?

Its broken work was conducted between the two pieces of jaw plate, which is called on a fixed to the frame fixed jaw plate, the other a perfectly on the movement of the moving jaw body called dynamic jaw plate, its surface is commonly tooth shape.When the moving jaw plate periodically near and far away from fixed jaw plate, crushing and discharging work done, now add an overload protection system, institutions can prolong the life of the machine better.

In mining engineering and construction, jaw broken machine is mostly used to crushing blasting mining of natural stone, makes the size of the ore or gravel.In the silicate industry, solid materials, fuel and semi-finished products need to go through all kinds of crushing processing, make it up to each procedure required for further processing.Jaw crusher and trip distribution is reasonable, and has a large vertical stroke, is advantageous to the crushing cavity material down, so the production capacity is higher than ordinary crusher about 30%.

PEW Jaw Crusher Working Principle

Motor passes motive power to eccentric shaft end’s pulley, making the eccentric shaft under lead of motor do rotatory movement according to the demanded speed rated; Dynamic jaw head propelled by the eccentric shaft’s eccentric force makes regular fixed track compressive to break the materials. The motor drives the belt wheel, and makes the move jaw up and down by eccentric shaft. When the movable jaw rises, the angle between the fixed jaw and movable jaw gets larger, and the materials can be crushed to reach the crushing target. When the movable jaw down, the angle between the fixed jaw and movable jaw gets smaller. The movable jaw plate leaves the fixed jaw plate under the function of drawbar and spring, and then the crushed materials are discharged from the lower outlet of the crushing cavity.
