And Jaw Crusher is widely used in mining, metallurgy, construction, highway, railroad, conservancy and chemistry industries,etc.Jaw crusher are mainly used to proceed the medium particles crushing of various ores and large size materials with the crushing pressure of less than 320Mpa .
To adapt the application of high hardness material, it needs to pay attention to the product quality of the casting, especially the installation to ensure that the geometry size and the shape error in the range of reasonable. It is stable and reliable to ensure the runtime.
PFW Europe Series Impact Crusher mainly consists of the rotor, impact support, frame, screw clamshell device and transmission parts etc.
The crushed stones are carried through a conveyor belt to the rotary grinder for grinding.The first stage is stone crushing, with stone blocks being manually fed through the hopper to a jaw crusher.
This is important because the control of slimes in other gravity separation processes is a pressing problem as evidenced by the discussions of the problem in the above-identified Aplan patent and in U. Pat. 8, 1938, to Crawford et al.Yet another advantage of our process is that, as far as we can observe, there is no tendency for slimes to form even in circumstances where significant amounts of clays are present.

The electric charge could save about 200,000 RMB each year by the main and auxiliary shaft. The design processing capacity was 500,000 t/a and the maximum washing capacity was 150t per hour. The lifting pressure of the deep well transportation was large. The underground dense medium shallow groove system was used for coal-waste separation. The lifting capacity of the main shaft was increased by 100,000 t. After the separation, the gangues were used for solid backfilling. Some mining areas in Xinjulong Mine were exploited under buildings. Eight hundred thousand t gangues could be separated each year.12 Coal Mine of Pingdingshan Group.Many mines in China have used coal-waste separation methods such as the dense medium shallow groove method and the vibro-assisted jigging method to implement backfilling mining after underground coal-waste separation of the raw coal. The separation capacity was 350~500t/h and the separable waste amount was 148,700 t every year. The implementation of underground coal-waste separation avoided the waste during the transportation and achieved coal-waste separation and separate coal-waste storing and transporting as well as improved the quality of the raw coal. These include the Zhaizhen Coal Mine of the Xinwen mining area, Xiezhuang Coal Mine, Xinjulong Coal Mine, the Tangshan Mine of Kailuan Group and the No. Among them, the underground coal-waste separation project in Zhaizhen Coal Mine was approved by the Company in August 2010 and put into use in January 2011. In order to solve the piled gangue on the surface, Tangshan Mine used underground vibro-assisted jigging separation and solid backfilling mining technology.
