Conclusions
-
1.
By means of graphs (Figs. 3, 4, 5), the depth of freezing of the sand-gravel mix is determined as a function of ambient air temperature and time.
-
2.
Knowing the actual depth of freezing of the mix as a function of ambient air temperature and time, it is possible to forecast laminar freezing of the sand-gravel mix in the hydraulic-fill stock pile and thus to choose the most economical method of operation.
Correct choice of machinery and method for removing the frozen portion of the mix from the stock pile increases the output of the gravel grading plant and provides high-grade aggregates.
