Jaw crusher instruction

We provide technical stone jaw crusher for sale and price of jaw crusher for ore processing. The price of jaw crusher we offered is proper and reasonable with many characteristics at the same time, such as higher size reduction ratio, homogeneous product granularity, simple structure, reliable working, convenience for maintenance, lower operating expenses and so forth.

Jaw crusher is widely applied in numerous departments including ore process, smelting, construction, highway, railway, water conservancy and chemical industry and some other ones for the crush of various materials with 320 MPa of compressive resistance at the most.

The use and serviceable range of jaw crusher

  1. This series of crusher is mostly used to secondarily crush and fine grind various kinds of medium hard ores and rocks in metallurgy, mining, cement, construction, refractory materials, ceramics and some other industry segments.
  2. This series of crusher is suitable for the crush of all kinds of soft or hard ores with compressive resistance lower than 300 MPa. Furthermore, the maximum blockiness size of the materials crushed mustn’t be larger than that ruled in the technical parameters table.
  3. Jaw crusher can be applied to the crush of multiple sorts of dry and fragile materials, such as the limestone and rocks. All the parts are easy to be cleared up, especially the surface of crushing parts. The jaw plate made of manganese steel can be used reversedly, which prolongs the lifespan of jaw plates to twice the length of common ones.

Jaw crusher working principles

The working mode of jaw crusher is through bending, wring and squeezing. The working principles of it can be described as below. The electromotor drives the strap and the pulley to make the moving jaw move up and down through eccentric shaft. The angle between the toggle plate and the moving jaw will become larger when the moving jaw rises, thus pushing the moving jaw plate close to the stationary jaw plate. At the same time, materials are crushed or split into pieces, which makes the purpose of crush achieved.

In contrast, when the moving jaw runs down, the angle between the toggle plate and the moving jaw will instead become smaller, then the moving jaw plate departs from the stationary jaw plate under the effect of draw bar and spring. At this moment, crushed materials discharge from the end opening of crushing cavity. The moving jaw of the crusher will make periodic motion to crush and discharge materials with the continuous rotation of the electromotor. Thereby, the mass production can be achieved.
