Jaw crusher and impact crusher What is the difference in the purposes

PF-I series crusher series suitable for crushing hard rock, the typical particle size ≤ 40mm granite out of 90%. Side of the machine can handle 100 to 500 mm material, the compressive strength of up to 350 MPa, with a crushing ratio, the material was broken cubic particles and so on.
PF-II series crusher series suitable for crushing of hard materials, the typical particle size ≤ 25mm granite out of 85%. Such as broken limestone cement. Productive capacity, the advantages of small particle size.
PF-III series crusher series adapted to the concrete crushing, the typical particle size ≤ 30mm granite out of 85%. With feed specifications, ability to deal advantages.
This series is suitable for crushing of hard materials such as cement limestone crusher, with a production capacity, the advantages of small particle size.
The use of Impact Crusher: This series of products capable of handling 100-500 mm below the material side, with compressive strength up to 350 MPa, with a crushing ratio, broken after the material was cubic particles and so on.
Works: the upper part of stone from the machine directly into the high-speed rotating wheel; under the effect of centrifugal force at high speed, with another way to divert part of the umbrella to fly around the wheel high-speed collision and stone have high density of crushed stone in the fight against each other after , will form between the turntable and the chassis caused by vortex motion against each other many times, friction, grinding, through discharge from the bottom. The formation of many closed loop control by the screening equipment to the required size.
Impact crusher features:
1, the machine is a new development in the nineties, chippings, and it is widely used to replace the world's cone crusher, roller, ball mill models.
2, the new structure, unique, smooth operation.
3, energy consumption, high yield, crushing ratio.
4, the devices are small, simple operation, installation and maintenance.
5, with a shaping function, the product was cubic-like, packing density.
6, the production process, form a protective stone to the bottom of the fuselage without wear and durability.
7, a small amount of wear parts made for extra hard wear-resistant material, small size, light weight, ease of replacement parts.


Jaw Crusher is mainly used for compressive strength of not more than 320 MPa in a variety of materials, broken, thick broken job, with a crushing ratio, high output, uniform particle size, simple structure, reliable operation, easy maintenance, operations costs and economic characteristics. The crusher is widely used in mining, smelting, building material, highway, railway, water conservancy departments.
Jaw Crusher Features:
Simple structure, easy maintenance; stable performance, low operating costs; crushing ratio.
Jaw Crusher Working Principle:
A variety of jaw crusher structure, working principle is the same, namely, by moving jaw broken the cyclical movement of materials. The moving jaw hanging around the heart of the process of axial oscillation of fixed jaw, located between the two jaw plates materials will be crushed, split and combined effects of bending. the beginning, less pressure, so reducing the size of the material, the material near each other, squeezing; when the pressure rises above the material's strength can bear, that is fractured. On the contrary, the fixed jaw when the moving jaw left swinging in the opposite direction when the downward movement of the material is by weight. moving jaw of each cyclical movement of materials by a crushing effect, some distance to the next carriage. After several cycles, begins with the material being broken discharge opening from the plane.
