Abstract:
According to the treatment processing status of the parent rock before its broken in producing aggregates, the change rule of fresh broken surfaces after the parent rock broken, and the differences of the different particle shapes, a mathematical model method was adopted to prove the feasibility of grading-broken theoretically, the control scope of screen hole size for undesirable rocks in grading-broken was obtained by an example. The results show that the broken control system can be developed by the above model to get the needed particle size and screen hole size before and after the crushing in practice, so the production quality of the aggregates can be improved, and the purpose of resource utilization maximization and energy consumption minimum is achieved at the same time. 4 tabs, 2 figs, 8 refs.
