Artificial sand production process The production process of artificial sand and gravel aggregate can generally be divided into the following stages: raw materials → coarse crushing → fine crushing → screening → washing → products. 1. Feeding material
In areas where natural sand and gravel aggregate deposits are insufficient to handle local demand, larger quarry rocks are processed in an impact crusher to create crushed-rock aggregate. In the quarry, the rocks are extracted and then transported to the rock crusher, which begins the process of crushing the larger quarried larger rock into more
Taking the 'adult period' of manufactured sand (MSC) as the end point, the flow chart of manufactured sand production was drawn. As shown in Fig. 1, the whole sand production process is an open-circuit production process, but a small closed-loop process is selected in the fine crushing process of crushed stone. On the one hand, it reduces ...
