The sand stone aggregates can be divided into gravel and fine sand according to the granularity of the final products. Different equipment is needed in order to produce the two kinds of raw materials. The equipment used for manufacturing gravels is medium and fine crushing equipment including impact crusher, jaw crusher and cone crusher; and the machines used for producing fine sands are fine crushing equipment include sand maker and vertical shaft impact crusher. As for the customers building sand and stone aggregates field, the series crushers manufactured by Shandong Jinbaoshan Mining Machinery Co., Ltd are the most suitable equipment.

The stone crushing production line is the same with the sand making production line in the essence since their purpose is to crush and process the stone materials. The only differences lie in the operational principle of the processing equipment and the fineness of the final products. With the increase of the demands for sand and stone concrete in our country, people put forward higher requirements for the production equipment of sand and stone. Driven by the market demands, reliable quality and stable working performance are the development trend of the present crushing machines. On the condition of encouraging to improve the process of the sand and stone aggregates, we should improve the product quality of the sand and stone aggregates and the production efficiency to a new height, for this reason. Hongxing Machinery continuously seeks for new technological breakthroughs in order to enhance the overall efficiency of the machine.
