Introduction of jaw crusher

Appeard in 1858, Jaw crusher is also called tiger mouth and firstly applied in the road building projects and later the mines. At present, it has found jaw crushers extensive use in the mining, metallurgical indutry, construction, road and railway building, conversancy, chemistry, etc. And jaw crushers pressure resistance is under 320MP. And the Jaw crusher produced by our company features simple structure, reliable function, long service life, low noise & energy consumption, low operation cost, convenient maintenance.So jaw crusher has occupied the absolute leading position.

Main Structure of jaw crusher

Jaw crusher mainly consists of fixed & moveable parts, secure & set adjustment and other components.

1.Fixed parts : the frame is the main fixed parts of the jaw crusher and there also have two mechanic manufacture crafts :medium carbon steel cast and steel welding plate frame.The welding frame have more several steel ribs on the basis of previous cast frame, which have reached the same using effects under the strict qualjaw crusher control and specific crafts requirements.To avoid serious wearing of frame’s sidewall, the guard has been installed on both sides of thecrushing cavjaw crusher so that we can change them at any time.

2.Moveable part : jaw crusher mainly consists of jawstock, eccentric shaft, bear, belt pulley and other components, which are the main parts of jaw crusher’s transmitting and bearing capability.

  a.The jawstock consists of the bracket and moveable jaw plate and the bracket adopts the 35# cast steel, which have been adjuseted and processed.

  b.The eccentric shaft adopts the 45#steel, which have also been adjuseted and processed.

  c.The bear adopts the double-row spherical roller wit the fearures of slight adjustment, large bearing capability and durability.

  d.There have moveable and fixed jawstock.To improve the crushing effect, jaw crushers surface adopts the optimization tooth shape and the materials adopts the ZGMn13 with the advantages of high hardness, abrasion-resistance, better effects and so on.

3.Set Adjustment equipment :jaw crusher is mainly used for adjusting the size of the discharge opening so that jaw crusher can control the discharging particle size. And jaw crusher mainly has two forms, that is long wedge and prop gasket, jaw crusherh flexible and no limit adjustment.

Jaw crusher consists of frame, eccentric shaft, jawstock, toggie plate, cheek plate(up and down), set adjustment, fixed and moveable jaw plate.And the toggie plate also play a role of securjaw crusher. The jaw crusher produced by our company adopts high-strength Mn-steel and has been forged wit one time shaped with features of abrasion-resistance, pressure-resistance and long service life.And now jaw crusher has been suit for crushing the large, mid &small stones and corresponding materials.

Products Advantages of jaw crusehr

Jaw crusher produced by our company features simple structure, reliable function, long service life, low noise & energy consumption, low operation cost, convenient maintenance. So jaw crusher has win its own international welcome and occupied the absolute leading position.

Working Principle of jaw crusher

This kind of jaw crusher uses motor as jaw crushers power. Through the motor's wheels, the eccentric shaft is driven by the belt and the belt wheel to make the jawstock move by a regulated track. And the materials will be crushed by the regular periodic movement .The materials between the two jaw plates will receive multi-crushing functions on the jaw plate . From the beginning, the pressure is small and the vloume of materials will be reduced when the space between the materials become closed and compact. And crush will happen when the pressure become high up when the strength materials can not bear . On the contrary, the materials will make free falling movement when the jawstock swing with the opposjaw crushere direction with the fixed jaw plate .The materials will be crushed in every periodic movement and delivered down a distance.After several kind of these periods, the final products will be discharged by the discharge opening .
