For the primary crushing and segmented crushing of mineral aggregate, we can understand it well, that is, using one crusher equipment for crushing or using multiple crusher equipment for combined crushing. For primary crushing equipment, we can choose hammer crusher and impact crusher, which are the most commonly used. Compared with them, hammer crusher is more suitable for primary crushing. For segmental crushing, we usually use jaw crusher, impact crusher, cone crusher or impact crusher. Matching these crushers has become the equipment we need to choose for subsection crushing.
From the equipment selected by these two crushing methods, we can see the choice we need to make when choosing stone crushing. The crusher we choose is suitable for crushing small and medium-sized stones, and the hardness of the broken stone should not be too high, so the broken stone does not need further shaping. As for segmental crushing, we usually break large pieces of high-hardness stones. First, it is treated by jaw crusher, then crushed by other three kinds of equipment, and finally it becomes the sand aggregate we need.
These two methods don't say which is good or not, only that they are suitable for users. If the stone you need is not so small, and the hardness of the stone is suitable for crushing, we can use one-time crushing and molding equipment. If the fineness of the required materials is small, and the fragmentation and hardness of the stone are large, the method of segmentation can only be chosen. Therefore, the two crushing methods have their own advantages and disadvantages, and we don't need to distinguish which method is good, just need to be suitable for our use.
