Since the waste rock chips have such a large application market, why don’t sand manufacturers directly use these waste rock chips to form an integrated production line mode? The main reason is that it is difficult to use the waste because of its characteristics.
1.At present, the waste rock debris is mainly used as concrete. We do not have a good grasp of the influence of the quality of waste rock debris on concrete.
2.There is a lot of mud in the waste rock chips, so it is difficult to remove mud, and the cost is large. Increasing the amount of cement has poor market acceptance.
3.Different types of waste rock chips need targeted deep processing technology, and some enterprises do not have a good understanding of it. As a result, the expected economic and environmental benefits are not realized, and the enterprises have no confidence to continue to do so.
