Brief Introduction to Jaw Crusher:
Jaw crusher is commonly known as Tiger Mouth, and the crushing cavity formed by the fixed jaw and moved jaw simulate animal JAWS to complete material crushing operation. Jaw crushers are widely used in mining, metallurgical industry, building material, highway, railway, water conservancy and chemical industries for medium breaking of various ores and large blocks. Highest compressive strength of crushing material for jaw crushers should be not more than 320Mpa.
Main Features of Jaw Crusher:
1. Deep crushing cavity and energy efficiency.
2. Strong bearing capacity and stability.
3. Advanced technology and long service life.
4. Simple maintenance with the centralized lubrication system.
5. Simple structure and maintenance.
6. Wide range of the discharging adjustment and multi-purpose.
7. Little noise and dust.
Working principle of jaw crushers stone jaw breaking machine:
Motor drives belt and pulley to make jaw moves up and down through eccentric shaft; when dynamic jaw rises, intersection angle between bracket and dynamic jaw largens and pushes dynamic jaw plate approach to the fixed jaw plate, meanwhile, the materials are crushed so as to achieve the purpose of crushing. When dynamic jaw descends, intersection angle between bracket and dynamic jaw diminishes; under the effect of queen bolt and spring, dynamic jaw plate deviates from fixed jaw plate, then broken materials are discharged from mouth of crushing cavity.
Note of Jaw Crushers  jaw breaking plant:
Before use jaw crusher,you should check all parts of the fasteners, especially the lubricating parts and the bolts, the lubricating parts must keep enough oil, loose bolts tighten, then clean up the broken cavity residue, and then boot production. In the normal work pay attention to feed evenly, not a sufficient, multi don't add, too much can cause mechanical blockage. Moving jaw plate, static jaw plate, on both sides of the plate, the roof for wearing parts, pay attention to maintenance.
