/ What is the difference between the two-stage crushing operation, the cone crusher and the counter-attack type?

Time: 2018-11

The cone crusher and the impact crusher are the two-stage crushing equipment in the whole production line. What is the main difference in the crushing? The working principle of the cone crusher is to use the laminated crushing, and the rolling wall is continuously broken. Wall movement, squeezing the material between the two to carry out pulverization; the working principle of the counter-crusher is to rebound from the material to the top of the vortex breaking chamber, and then rebound and fall freely, and continuously break with the impact material .

There are also many differences between the two in actual production, as follows:
1. The hardness of the broken material is different
Counter-breaking and conical breaking can be used as secondary crushing equipment, but the hardness of the broken materials is different. The cone crushing mainly breaks some hard materials such as granite, basalt, tuff, river pebble, etc. Broken materials with less hardness, such as limestone, limestone, etc.
2, the discharge granularity and the applicable materials are different
The size of the material discharged from the two crusher equipments is also different. In general, the cone is thinner than the broken material. In actual production, there are more cones used in beneficiation, and more counter-attacks are used in building materials and construction projects.
3, the finished grain type is different
The shape of the broken particles is good, the corners of the finished product are less, and the powder is more; the finished product with a conical shape has more needles and a smaller shape.
4, the amount of processing is different
Compared with the counter-attack, the cone-breaking has the characteristics of low energy consumption, large output, stable production, etc., so the cone is often used for large-scale high-yield production line operations.
5. Different input costs
The price of the cone is more expensive than the counterattack, but the longevity of the consumables is long, avoiding the trouble of frequently replacing parts. In the long run, the cone is more expensive than the counterattack.
It can be understood that the pre-recovery cost of the counter-attack is low, and the post-maintenance cost is high; the pre-cone cost of the cone is high, and the input cost is low later.
6, the degree of pollution is different
Counter-attacking noise pollution and dust pollution are large; cone-contaminated pollution is less.
In summary, counterattacks and cones have their own advantages and disadvantages. Which equipment should be used in actual production, and also needs to be selected according to different materials, grain size and output. It is suggested that if it is a small stone production line, it will be broken if it is a large stone production line. If the material is hard and the material is hard, it is better to choose a cone. If the grain type is very strict, you can add a plastic machine.
