The same is crushing. Many people will wonder why cone crushers are sometimes recommended and counterattack crushers are sometimes recommended. From this, Xiaobian thought that there may be many friends who are new to the crushing industry who don’t know much about the two types of equipment, cone breaking and counterattack breaking, so Xiaobian’s article here today mainly talks about how to choose to use a cone crusher or a counterattack crusher for crushing. Crusher or counterattack crusher?
How to choose whether to use a cone crusher or a counterattack crusher for crushing?
The same is the secondary crushing equipment. The obvious difference between the impact crusher and the cone crusher lies in the different crushing principle and appearance structure, which is easy to distinguish.The impact crusher adopts the principle of impact crushing, and the material is repeatedly impacted and broken between the hammer and the backing plate; the cone crusher adopts laminated crushing, and the rolling mortar wall continuously moves towards the crushing wall, squeezing the material sandwiched between the two and forcing it to crush.Next, use limestone as an example：
For the same limestone, why do some people use cones to break, and some people use counterattacks to break?This is mainly due to the vast area and large geographical range of our country. Although both the north and the south are called limestone, due to the different natural formation environments and conditions, the mixed components in limestone are different. Generally speaking, the Mohs hardness of limestone is between 3.5-4, and it can be broken by counterattack; however, if there are more impurities in limestone, it will also increase the overall hardness of the stone, which is not conducive to counterattack breaking and crushing. At this time, it is not advisable to choose cone breaking and crushing.
Through the above simple example, I believe everyone has a certain understanding. Next, we will explain from a more professional perspective how to choose whether to use a cone crusher or a counterattack crusher for crushing.：
Choose cone crusher or counterattack crusher according to the hardness of the stone：
- Choose a cone crusher for hard and abrasive stones, which has high crushing efficiency, large production capacity, uniform particle size and reliable operation of the finished product.
- For medium-hard and soft stones with low abrasion resistance, choose a impact crusher with high output, good discharge, safety and reliability, energy saving and environmental protection.
Choose cone crusher or counterattack crusher according to production needs
- The output is large, the energy consumption is low, and the discharge requirements are not large. Choose a cone crusher.The hourly output of single-cylinder cone crusher is between 55-1850 tons. The output is large, which can meet the user’s demand for high production. At the same time, it consumes low energy, runs smoothly, has a low failure rate, has a long replacement cycle of wearing parts, and has low late operating costs. , The discharge particle type is good, suitable for stone crushing production lines with high-yield requirements.
- High efficiency, low investment, and high requirements for particle size, choose a counterattack crusher.The counter-breaking operation is efficient and the purchase cost is low. The plate hammer and hammer head are easy-to-wear parts and need to be inspected and replaced regularly. The principle of percussion crushing makes the product have a better particle shape, and the finished product is a square body without tension and cracks. It is suitable for stone crushing production lines with high requirements for product particle shape.
The above is the method of choosing to use a cone crusher or a counterattack crusher.
