When many customers inquire about equipment configuration, they will inevitably have such questions: the same limestone is used as raw material, some are used cone crushers, and some are used impact crushers; And the same granite is used as raw material, and some of them use impact crushers. Usually, are not soft materials used for impact crushers and hard materials used for cone crusher? To this end, this article will briefly introduce the difference between cone crusher and impact crusher, perhaps for everyone to do a reference.
What is the difference between cone crusher and impact crusher?
I. Different scope of application
Cone crusher is mainly suitable for crushing ore and rock of medium hardness or above, such as granite, basalt, river stone, copper ore, diabase, etc. Impact crusher is mainly suitable for crushing stones with low hardness, such as limestone, river pebble, coal gangue, etc.
Aiming at the different problems of the equipment selected by customers for the above limestone materials, due to the rich mineral resources and wide distribution, as well as the various natural formation environments and conditions, the mineral composition is different and can be mixed with other impurities, thus the hardness also differs slightly. Generally, impact crusher can be used for limestone with Moh's hardness of 3.5-4. If there are more impurities present, the hardness of the limestone will increase and a cone crusher is a good choice for this situation.
2. Different composition structure and crushing principles
(1). Composition structure
Cone crusher consists of moving cone, adjustment sleeve, feed hopper, feeding tray, spherical bearing, main frame, eccentric sleeve, hydraulic system, base, spindle, transmission shaft, pulley, etc.
Impact crusher consists of a maintenance boom, dust-proof chain, side liner, impact liner, heavy-duty rotor, flat hammer, rack, hydraulic system and belt pulley.
(2). Crushing principle
Cone crusher: The material is crushed by the principle of lamination crushing, with high crushing efficiency and low wear of wearing parts.
Impact crusher: the use of impact energy to crush materials, by adjusting the installation of the impact rack position, to achieve the coarse crushing and fine crushing conversion, one machine for two purposes.
3. Different capacity
Cone crusher has a capacity of 15-2200 t/h, which offers a large and stable production capability, and is typically used in large-scale and high capacity production lines. Impact crusher has a production capacity of 15-700 t/h, processing capacity is relatively small, but the final product of good particle shape, is usually suitable for small and medium-sized production lines.
In the case of small capacity and high requirements on the quality of the final product, impact crusher can also crush granite. However, wearing parts the wear rate is relatively high, it is recommended to replace the parts with high wear resistance or replace the wearing parts in time.
4. Discharge size final product different grain shapes
The discharge size and the final product of the materials crushed by cone crusher and impact crusher are different. In general, the cone crusher is finer than the material crushed by the impact crusher, and in actual production, the cone crusher is used more in beneficiation. Impact crusher, the final product has good particle shape, uniform particle size and fewer needle flakes, and is often used in industries with strict discharge requirements such as building materials, construction, sand and aggregate.
5. Different wearing parts
The main wearing parts of cone crusher are crushing wall and concave.
The main wearing parts of the impact crusher are the flat hammer, impact block and liner.
Through the above difference between cone crusher and impact crusher, do you have a certain understanding? As for which equipment needs to be selected according to the material, input and discharge size, capacity and other conditions, combined with actual requirements comprehensive consideration, such as you have other crushing, sand and other issues, you can consult us for details.
