Cone crusher and impact crusher are indispensable two-breaking equipment in large and small production lines. Many customers do not know the difference, so there will be difficulties in choosing. In fact, because of the differences in various aspects, the two also have their own strengths in specific production.Today we will talk in detail about the difference between cone crusher and impact crusher.
What is the difference between a cone crusher and a impact crusher?
- Different types of broken stones
The hardness range of materials commonly used for crushing by counterattack breaking and cone breaking is not the same.Generally speaking, cone breaking mainly breaks some materials with higher hardness, such as granite, basalt, tuff, river pebbles, etc., while counter-breaking is used to break materials with lower hardness, such as limestone, limestone, etc.In a word, counterattack breaking is suitable for crushing materials with low toughness and brittleness of medium hardness and below, and cone breaking is suitable for crushing hard materials.
However, some of the stone hardness that does not conform to common sense, taking into account the economy and practicality, the two can also be used instead of each other.
- Different operating principles：
The cone crusher adopts the principle of laminated crushing.During operation, the particles and the liner, the particles and the particles are kneaded with each other, so that the flat and long strips of particles break along their weak parts, and the material to be broken is broken multiple times in the crushing chamber. The finished product has finer particles, less needle-like content, and good particle shape, which can meet the special particle shape requirements of hydropower, urban construction, highway, railway and other industries.
The impact crusher uses the principle of impact crushing.During operation, driven by the motor, the rotor rotates at high speed. When the material enters the plate hammer effect area, it collides with the plate hammer on the rotor and breaks, and then is thrown to the counterattack equipment to break again, and then bounces back from the counterattack liner to the plate hammer effect area to break from scratch, repeat this process until the material is broken to the desired particle size.
- Different discharge particle types：
While crushing the material, the impact crusher also has a certain function of shaping the particles of the discharge. The particles of the sand and gravel material after processing are cubic in shape, with uniform size, no tension and cracks, low needle flake content, reasonable grading, and beautiful particle shape.
In contrast, although the crushing effect of the cone crusher is also good, it is still slightly inferior to the impact crusher in terms of shaping the discharge particles.
- Different wear resistance：
There are more vulnerable parts of impact crushers, such as hammer heads, impact plates and other parts that need to be replaced frequently, so the loss and depreciation of equipment are faster, and the later operation and maintenance costs are higher.
The wearing parts of the cone crusher have a relatively long life span and there is no need to replace parts frequently, so the loss and depreciation of the equipment are slower, and the later operation and maintenance costs are lower.
- Different production capacity sizes：
The impact crusher adopts a sturdy and heavy-duty rotor structure, which improves the material handling capacity and crushing ratio, thereby increasing its crushing capacity.Overall, the production capacity of impact crushers is between 90-1550t/h.
The cone crusher combines the high crushing cavity type with the high crushing frequency well, and adopts a fully automatic control system of PLC +touch screen, which effectively improves its material processing capacity.Overall, the production capacity of the cone crusher is between 55-2181t/h.
- Different production costs and different sales prices
The price of cone breaking is more expensive than counterattack breaking, but its wearing parts have a longer life span, avoiding the trouble of frequent replacement of parts. In the long run, cone breaking is more cost-effective than counterattack breaking.
It can be understood that the early purchase cost of cone breaking is low, and the later maintenance cost is higher; the early cost of cone breaking is high, and the later input cost is lower.
In summary, it can be seen that counter-breaking and cone breaking have their own advantages and disadvantages. In actual production, we also need to choose which equipment to choose according to different materials, inlet and outlet particle sizes, and output.It is recommended here that if it is a small stone production line, use counter-breaking tools.If it is a large stone production line and the material is harder, choose a cone crusher.
The above is the difference between cone crusher and impact crusher.
