The impact crusher and cone crusher are generally used after the jaw crusher. They are the secondary medium crushing equipment comm used in the crushing production line. Then users will face such questions when choosing the secondary crushing equipment-counterattack How to choose between crusher and cone crusher? The following editor will take everyone to understand the difference between impact crusher and cone crusher, and help you make your own decision.
Working principle is different
1. The impact crusher uses impact energy to crush materials. When working, the motor drives the rotor to rotate at a high speed, and the material enters the hammer work area, hits and breaks with the hammer on the rotor, and then is thrown to the counterattack device to break again, and then rebound from the counterattack liner back to the hammer action area Re-crushing, this process is repeated, the material enters the *, second, and third counterattack chamber from large to small, and is repeatedly crushed until the material is crushed to the required particle size and discharged from the discharge port. Adjusting the gap between the counterattack frame and the rotor can achieve the purpose of changing the size and shape of the material discharged.
2. The cone crusher crusher uses the principle of laminated crushing to crush materials. When working, the motor drives the eccentric sleeve to rotate through the V-belt, large pulley, transmission shaft, small bevel gear, and large bevel gear. The main shaft rotates and swings under the force of the eccentric shaft sleeve, so that the broken wall is sometimes close to and away from the rolling mortar wall. , So that the material is continuously impacted, squeezed and bent in the annular crushing cavity composed of the fixed cone and the movable cone to be broken. After many times of extrusion, impact and bending, the material is crushed to the required size and discharged through the lower part. Adapt to different material hardness
1. The impact crusher is suitable for crushing various materials with low hardness and brittleness, such as limestone, coal gangue, bricks, concrete, etc.
2. Cone crusher is mainly used to crush materials with medium and medium hardness and higher hardness, such as: river pebble, marble, quartzite, granite, basalt, etc.
Different shape of the finished product
1. The discharging products of the impact crusher and the cone crusher are different. The impact crusher has the function of fine adjustment. The discharging product has good grain shape and *ly cubic shape, but the discharging particle size is relatively coarse (its discharge The size of the mouth is adjusted between 10-50mm), which is more used in construction, building materials and other industries.
2. Cone crusher has a finer granularity of the finished product (the size of the discharge port is adjusted between 4-65mm), which is more used in ore dressing.
Input and use costs are different
In terms of price, cone crushers are slightly more expensive than impact crushers. However, cone crushers have lower energy consumption, more stable production, and service life of vulnerable parts. To avoid the trouble of frequent shutdowns for maintenance and replacement of parts; although the initial purchase cost of the impact crusher is low, the later maintenance cost is higher than that of the cone crusher. Therefore, from a long-term perspective, the cone crusher Is more cost-effective
Based on the above analysis, although the impact crusher and cone crusher are both secondary crushing equipment for crushing production, they have similarities and differences and their advantages. The difference is still relatively large. Which crushing effect is specific? Better still, it is necessary to make a reasonable choice based on the specific requirements of the user's actual material characteristics, output requirements, and the effect of the finished product.
