How to Choose Rock Crushers According to Different Rock Types

China has vast territory and abundant resources, especially in natural resources. And there are various kinds of minerals in nature. In addition, they include several kinds depending on the different features. And they also can be divided into the extreme hardness, medium hardness and low hardness at different levels according to the hard degree. While using crusher to crush ores also can choose rock crusher according to the degree of hard rock, avoiding causing the waste of resources.

As for some minerals with extreme hardness, such as quartzite rocks, sandstone, marbles, shale and sandstone ore, which are fine and solid, so you should choose crushing equipment with high crushing capacity like jaw crusher. Using other crushers which use hammer and grinding way will make the machine suffer severe wear and tear, and causing not excellent effect. So we should choose the appropriate crusher, and jaw crusher is the best choice.

For some medium hardness ore, these kinds of ores can use jaw crusher to crush, also can use the heavy hammer crusher, impact crusher, and roller crusher, counterattack crusher, and hammer crusher to carry out crush. Optional range is wide, so the customers can make reasonable choice combining their own conditions.

For some ore that has low degree hardness, and weak compressive strength, such as the weak shale, chalk, halite, gypsum, anthracite, ordinary marl, crushing integration of sandstone, rocky soil, and broken shale and so on, it is not necessary to use jaw crusher to proceed with crushing. Choosing hammer crusher or roller crusher and mixed crusher is fairly enough.

Actually to sum up, general ore materials, no matter how hard, can utilize jaw crusher to carry out crushing. However, considering the cost and the actual situation of the customers, it is advised to choose a suitable model. On the one hand suitable rock crusher makes work more efficient, and on the other hand it also can save money, avoiding the waste of resources. What’s more, the proper crushing step is also a good way to maintain the crushing equipment, because if the hardness is larger than the crushing capacity, it will cause the wear off of the crushing machines. Thus, choosing crushing machines in according to the rocks’ kinds is very significant, which makes sure the safety of the operators and does little harm to the environment you work with.
