Brief Introduction to Jaw Crushers

Jaw crushers are crushing plants that complete the material crushing process through the crushing chamber composed by movable jaw and fixed jaw that stimulates the movement of the two jaws of animals. They are widely used for the coarse granularity and medium granularity material crushing in the industries of mining, metallurgy, building material, highway, railway, water conservancy and chemistry. The highest compression strength of the materials to be crushed is 320Mpa.

According to the width of the feeding mouth, jaw crushers are divided into large, medium and small types; jaw crusher whose width of the feeding mouth is bigger than 600MM is large machine; whose width of the feeding mouth is 300-600MM is medium machine and whose width of the feeding mouth is smaller than 300MM is small type machine. Jaw Crushers are simple in structure, easy in production, reliable in working condition and convenient in use and maintenance.

Types and Classifications of Jaw Crushers

According to the swinging means of the jaw plate, jaw crushers can be divided into simple pendulum jaw crusher, complex pendulum jaw crusher and compound pendulum jaw crusher.

Advantages of Jaw Crusher

(1) It effectively solves the problems of high operation rate and no repair time due to low productivity.

(2) It can complete the crushing of large-sized limestone and the maximum crushing grain diameter is 1000*1200mm.

(3) The mixing uniformity of the two materials is good and the mixing amount of the desulfurization limestone greatly increases, thus effectively reducing the cost of raw materials.

(4) The electricity consumption is reduced.

(5) The granularity of the waste material is small.

(6) It effectively improves the working strength and working environment of the labors.

Performance Features of Jaw Crushers

(1) The crushing chamber is deep and without dead area, thus improving the feeding ability and output.

(2) The crushing ratio is big and product granularity is even.

(3) The gasket type discharging adjustment device is reliable and convenient, and the adjustment ranges are wide, thus increasing the flexibility of the equipment.

(4) The lubrication system is safe and reliable; the changing of spare parts is convenient and the maintenance workload is small.

(5) Jaw crushers are simple in structure, reliable in working and low in operational fees.

(6) This equipment saves more energy.

(7) The machine has low noises and less powder dust.

Working Parts and Principle of Jaw Crushers

The working parts of jaw crushers are two jaw plates: one is fixed jaw plate which is vertically fixed on the front wall of the machine and the other is movable jaw plate which is slant and forms a crushing chamber together with the fixed jaw plate. The movable jaw plate regularly and repeatedly moves to and away from the fixed jaw plate. When it moves away from the fixed jaw plate, the materials go into the crushing chamber and the final products are discharged out from the bottom of the machine; when it moves to the fixed jaw, the materials between the two jaw plates are squeezed and impacted and finally crushed.
