large jaw crusher (PE-900 × 1200) and Medium-sized stone jaw crusher (PE-600 × 900 or PE 69 Jaw crusher)

Yifan Machinery production of jaw crusher is a combination of crushing the field for many years experience in machinery manufacturing, devote themselves to come up with a highly efficient, energy-saving crushing equipment. Medium-sized jaw crusher (PE-600 × 900 or PE 69 Jaw crusher) and large jaw crusher (PE-900 × 1200) is one of the main export products of our company, especially in the design and production of large jaw crusher, both at home and abroad absolutely leading level. Medium size crushing, crushing compression strength not more than 320Mpa materials mainly used for a variety of ores and bulk materials, sub-coarse and fine broken two kinds. The product specification is complete, feed particle size of 125mm ~ 750mm, the primary crushing preferred equipment. Jaw crusher (cracker) are widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical and other industries.

Large jaw crusher PE-900 * 1200 

Large jaw crusher PE-900 * 1200 operating environment:
The huge stones broken into small stones process, the first crusher is usually referred to as a "master" crusher. The longest history and the most solid crusher jaw crusher. Jaw crusher feeding material from the top of the entrance into the crushing chamber containing E teeth. Jaw teeth with great force the material to the top of the wall will be broken into smaller stones. Support of Hubei tooth movement is an eccentric shaft, this axis throughout the body architecture. The eccentric motion is usually generated by a flywheel fixed on the shaft ends. Flywheel and often eccentric support bearing spherical roller bearings, bearing extremely harsh working environment. The bearings must withstand tremendous impact load, abrasive sewage and high temperature. Although this work is extremely harsh environment, jaw crusher still need to work very reliably, which is to ensure the efficiency of the production of a key ring.

PE-900 * 1200 Jaw crusher works:
The structure of the jaw crusher frame, eccentric shaft, big pulley, flywheel, moving jaw, side guard plate, toggle plate, toggle plate back seat, adjust gap screw, reset spring, fixed jaw plate and activities jaw , which brackets also play a role as insurance. The series jaw crusher way for music moving extrusion type, motor-driven belt and pulley, the up and down movement of the movable jaw by the eccentric shaft when the movable jaw rises, the angle between toggle plate and moving jaw becomes larger, thus promoting the movable jaw plate close to the fixed jaw plate, at the same time the material is squeezed, rubbing, grinding, such as multiple broken; when the movable jaw down, the angle between toggle plate and moving jaw smaller, movable jaw plate trolley leave spring fixed jaw plate, the crushed material is discharged from the crushing chamber mouth With the motor continuously rotating broken motor Hubei periodically crushed and nesting to achieve mass production.

PE-900 * 1200 Jaw crusher performance characteristics:
1. Crushing chamber depth and no dead zone, increased capacity and output feed;
2. Broken than large, uniform particle size;
3. Gasketed discharge opening adjustment device, reliable and convenient adjustment range, to increase the flexibility of the device;
4. Lubrication system is safe and reliable, easy to replace parts, maintenance workload is small;
5. Simple structure, reliable operation, low operating costs.
6. Equipment energy-saving: stand-alone energy-saving 15% to 30%, saving more than doubled;
7. nesting population adjustment range, to meet the requirements of different users;
8. Low noise, less dust.
