The aggregate is essential raw material which is indispensable for the construction of railways, highways, bridges, and house. The production of the aggregate cannot be separated from the help of sand making equipment. The sand making machine can refine the coarse aggregate into fine aggregate and meet the different construction requirement. With the developing of the national economic, large amounts of sand makers are applied into the engineering construction and greatly promote the booming of the economic. With the quick development of sand making production line in the engineering construction, there has a higher requirement on the sand quality.
