Jaw crusher and impact crusher are commonly used equipment for mining crushing, what is the difference between them? From the scope of application, working principle, performance characteristics of the three aspects of analysis.
First, the scope of application is different
Jaw crusher is often used in mining, coal mining, sand and gravel quarry, concrete mixing plant, dry mortar, power plant desulphurisation, building materials, smelting and other industries, suitable for crushing limestone, quartzite, iron ore, lapis lazuli, cobblestone, granite, basalt, shale, copper, steel slag and other materials.
Impact crusher is used in many industries such as building materials, mining, metallurgy, transport, railway, etc. It is suitable for crushing limestone, quartz, dolomite, sulphide iron ore, coal and other brittle materials below medium hardness.
Second, the working principle is different
Jaw crusher adopts the method of bending and squeezing to crush materials, the motor drives the belt and pulley, through the eccentric shaft to make the movable jaw move up and down, when the movable jaw rises, the angle between the elbow plate and the movable jaw becomes larger, so as to push the movable jaw plate to approach to the fixed jaw plate, and at the same time, the materials will be crushed or chopped, so as to achieve the goal of crushing; when the movable jaw is down, the angle between the elbow plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate, and the material will be broken under the effect of the tie rods and springs, then the movable jaw plate will move away from the fixed jaw plate. When the movable jaw moves downward, the angle between the elbow plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and spring. With the continuous rotation of the motor, the crushing motor jaws move periodically to crush and discharge the materials, achieving mass production.
Impact crusher uses impact energy to crush materials. The motor drives the rotor to rotate at high speed, when the material enters the plate hammer area, it crushes with the plate hammer on the rotor, and then it is thrown to the impact device to be crushed again, and then bounced back to the plate hammer area to be crushed again from the impact lining plate, and the process repeats, and the material enters into the first, second, third, and third impact chambers to be crushed repeatedly, until the material is crushed to the required granularity, and then it will be discharged from the discharge port.
Third, different performance characteristics
Jaw crusher performance advantages:
1、Low working noise, environmental protection and high production: the equipment in the work of low noise, can reduce noise pollution. At the same time, it can be matched with equipment to remove dust, which produces less dust. Thus effectively protect the surrounding environment and reduce pollution.
2、Advanced crushing process: advanced crushing process, the use of advanced digital parts processing equipment, so that the internal structure of precision. Deep cavity crushing without dead zone, the material in the crushing cavity will not occur in the blockage phenomenon, improve the production efficiency.
Impact crusher performance advantages:
1、Good granularity of crushed products: large feeding opening, high crushing cavity, high hardness of adapted materials, less stone powder. The gap between the impact plate and the hammer can be easily adjusted, effectively controlling the size of the discharged material, and the particle shape is good.
2、High production capacity, good efficiency: high chrome plate hammer, anti-impact, anti-wear, high impact force. Full crushing function, high productivity, low wear and tear of machine parts, high comprehensive efficiency.
