Operation of hydraulic solid materials transport systems under conditions with dry charging of earth

Conclusions

• 1. In the first approximation, the calculation of dry materials charging regimes can be done by the usual method used for calculating hydraulic transport systems operating on liquids with varying densities.

• 2. In the case of dry charging of earth, there is a region of the most economical operating conditions of hydraulic transport systems for a specific saturation of the active flow with earth. The consistency of the mixture for this saturation can be called optimal, because the minimum specific expenditures of electric power correspond to it.

• 3. The operation of hydraulic transport systems in the recommended regimes increases considerably the economy of these machines by increasing the consistency of the mixture to the optimal, which ultimately leads to a decrease of the specific expenditures of electric power.
