2021-5-24 In order to obtain aggregate products in line with national standards, the selection of aggregate production equipment plays a decisive role in the design of the production line, which mainly depends on the physical properties of the raw materials (such as the hardness of the raw materials, the abrasiveness index, the soil content, etc.) and the local Market demand. The aggregate production process is determined as a three-stage crushing system consisting of a rotary crusher

Con-sequently, the crushed aggregate particles will require more water to float them past adjacent particles than will the rounded aggregate. Crushed aggregates are also normal-ly covered with residue from the crushing process (crusher dust). This

2016-6-2 waste. One possible source of construction aggregate is sand that has been manufactured from the surplus material (crusher dust) that results when coarse aggregate is produced in hard rock quarries. Coarse aggregate production typically yields 25% to 45% crusher dust depending on the parent rock, crushing equipment and crushing conditions [2].
