How is energy used in working process of jaw crusher

Jaw crusher is suitable for primary and secondary crushing of rocks with compressive strength of less than 320 MPa. It is widely used in mining, metallurgy,adhesive film construction, highway, railway, chemistry industry, etc. All models are available according to your different fineness requirements. 

For quite a long time, the granularity was treated as equal to grinding effect. As a result, the macro size reduction was the focus of research while the grinding effect was neglected. Actually, granularity reduction is the macroscopic expression of inner micro damage under the effect of stress. So an inseparable relationship exists between them. 

The energy consumption of jaw crusher in the process of impacting has always been the emphasis of research. It is not just the foundation for coal crushing, but the key to appropriate, highly efficient crushing equipment. Whereas,prepreg due to the limitation of theory and practice, the research on energy consumption law in the process of coal crushing and micro crushing mechanism are not mature enough. The crushing effect can be reflected by the damage accumulation formed by the extension of micro crack in the coal and the macro size reduction caused by fracture. 

The macroscopic expression varies with the extent of granularity reduction. We can see from brittle fracture criterion and energy dissipation law that when energy loading reaches a threshold, the energy will be unavailable without fracture extension or damage. When energy loading reaches brittle fracture criterion, the coal will be crushed with damage degree of l and 15% unavailable energy. The coal storing capability increases with continuous energy loading. Consequently, the crushing size of coal will continuously reduce, meanwhile, the damage degree will be measured by lumpiness distribution. 

This series of crushers have a fixed jaw and a movable jaw, with the former fixed in front of the rack and the latter hanging on the mandrel. When the eccentric shaft rotates, the connecting rod moves from top to bottom, which makes the two thrust plates move repeatedly. With the pushing of the thrust plates, the movable jaw hanging on the mandrel can move from side to side. When the movable jaw sways to the fixed jaw, the material falling to the cavity will be crushed by the squeezing of the boards. When the movable jaw leaves the fixed jaw,This is giving a courageous and sexy look for your personality. The Cursher is now available in cheap cost and also available in high cost. This is suitable for every woman. Mostly this is wear young women. This is born in western country. But now this is famous in all over world.Wear for many years mini knee type dress. the crushed material will be discharged from the discharge port under the cavity. Thus, the working of mobile jaw crushers is intermittent, with the processing of crushing alternates with that of discharging. Furthermore, since the movable jaw moves around the mandrel while it is working,According to different Household scissors, this series of portable crushing plant can be operated as independent units, or as two-stage crushing plant with primary and secondary crushing, or as three-stage crushing plant with primary, secondary, and tertiary crushing. the crushing ratio has always been 3 to 6. Due to its simple movement,carbon sheets this type of jaw crusher is also called simple swing type jaw crusher.
