Primary gravel crushing and screening equipments

Primary gravel crushing and screening equipments： primary crushing crusher, secondary impact crusher and cone crusher, following sand making machine, and finally grinding mills. Gravel plays a very important role in construction, without aggregate, cement will not be formed when mixing with water, and it will lead to unusable. So in the construction industry, the aggregate is leading a very important role. Gravel is an indispensable building material, widely used in construction, roads, highways, railways, engineering and other fields.
