Sand Production Line for Rock Gravel with Medium and High Hardness

New urbanization will speed up the development of the domestic economy, also will have a significant amount of infrastructure. Demand for sand stone in the building is very large, and the application sand production line is relatively optimistic. In sand production line process, we come into contact with a wide variety of rock, such as river gravel, basalt, diabase, tuff, granite, limestone, with various hardness and different compressive strength, so they have different requirements on sand production line for rock gravel.

In limestone sand production line, we usually use two kinds of mainstream, one is jaw breaker and hammer breaker, another is jaw crusher and impact crusher, and both this two kinds of sand production lines are with compared low investment. The mode of jaw crusher and impact crusher has compared good aggregate grain type, which can enhance supply capacity of stone factories for senior road, railway, port, airport, etc.

In the sand production line of river gravel and basalt rocks and other hard materials, the mode of jaw crusher and impact crusher is inappropriate, because the hammer of impact crusher will be wore very serious, and need to replace the hammer about 20 days once, which will increase the accessories costs, and waste time of replacement and delayed time of normal production time.
