1. Application:
Jaw crusher is commonly used in a broken, will be a lot of material is suitable for the secondary crushing in such as cone crusher, impact crusher machine, such as feeding equipment, if the feed is very big, must use the jaw broken as the first stage crushing, and impact crusher broken is generally not suitable for marble, granite, too hard materials, this will be a big loss for wearing parts.
2. Scope of work:
Jaw crusher is mainly used for medium particle size crushing of all kinds of ores and bulk materials. Materials with crushing compressive strength less than 320Mpa can be divided into coarse crushing and fine crushing. This series of products have complete specifications, and the feeding particle size is 125mm ~ 750mm, which is the best choice for primary crushing equipment.
Impact crusher finished product is cubic, no tension and crack, good particle shape phase, can break feed particle size not more than 500mm, compressive strength not more than 50MPa all kinds of coarse, medium and fine materials (granite, limestone, concrete, etc.), the size of the discharge can be adjusted, crushing specifications diversification.
3. Working principle:
When the jaw crusher works, the motor drives the belt and pulley to move the movable jaw up and down through the eccentric shaft. When the movable jaw rises, the Angle between the bracket and the movable jaw becomes larger, so as to push the movable jaw plate closer to the fixed jaw plate. At the same time, the materials are crushed or split to achieve the purpose of crushing. When the movable jaw moves down, the Angle between the bracket and the movable jaw becomes smaller, and the movable jaw leaves the fixed jaw plate under the action of pull rod and spring. At this time, the crushed materials are discharged from the lower mouth of the crushing chamber. As the motor continuously rotates and the motor jaw is broken, the motor jaw moves periodically to crush and discharge materials to realize mass production.
Impact crusher break at work, under the drive of the motor, the rotor high-speed rotation, the material into the plate hammer function area, and the rotor plate hammer impact broken, and then again to counter device is broken, and then back to the board from the back plate hammer function area is broken again, this process is repeated, material from big to small into one, two, three, back cavity repeated broken, until the material being broken to the required size, is being exhausted from port discharge.
4. Performance:
Jaw crusher has: deep crushing chamber and no dead zone, improve the feeding capacity and output; the crushing ratio is large and the particle size is even. Gasket type discharge mouth adjustment device, reliable and convenient, wide adjustment range, increase the flexibility of the equipment; Simple structure, reliable operation and low operating cost. Equipment energy saving: single machine energy saving 15% ~ 30%, system energy saving more than double; Wide adjustment range of discharge port can meet the requirements of different users; Low noise, less dust.
The impact crusher has the following advantages: large feed port, high crushing chamber, high hardness, large lumpiness and little stone powder; the clearance between counter plate and hammer can be adjusted conveniently and the particle size can be controlled effectively. Compact structure, strong machine rigidity, the rotor has a large moment of inertia; High chromium hammer, impact resistance, wear resistance, impact force; No key connection, convenient maintenance, economical and reliable; Full crushing function, high productivity, low abrasion and high comprehensive benefit.
