The drum rotation is powered by the transmission mechanism gears and drum gear ring, with the transmission mechanism consisting of an electric motor, reducer, V Gear-driven assembly featuring excellent transmission, high load-bearing capacity, smooth operation, long service life, compact structure, and easy installation and maintenance. The water-cooled drum cooling bed utilizes the sand mold being reversed at a specific angular velocity by the sand-throwing plate inside the drum, the blowing of an axial flow fan, and rainwater cooling on the drum to achieve temperature reduction. The blowing of the axial flow fan also aids in dust collection. This machine boasts significant features such as large sand output, low energy consumption, excellent cooling performance, effective dust removal, and low noise, making it one of the ideal equipment for cooling sand molds.
