The paper is devoted to solving the problem of increasing the efficiency of discharging powdered cement from metal tanks using an air-pulsed booster. The results of research on the experimental facility and the method of transition from them to production tanks, which are most common in mortar-concrete installations and inventory warehouses of cement, are presented. The scheme of the experimental stand developed by the authors is given. The authors obtain experimental dependences of the effectiveness of cement collapse on the power in the system of pulsed air supply and the effectiveness of its collapse on the size of the gap. Further, the paper establishes the nature of the outflow and the formation of cement hang at the bottom of the tank. Based on the results of experimental studies using the similarity theory and dimensional analysis, the parameters of the system of cement collapse in real tanks are determined. |
