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, 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 in the conveying process, where the drum's sand-ejecting plate reverses at a specific angular velocity, the axial flow fan blows air, and the drum is subjected to rainwater cooling to achieve temperature reduction. The airflow from the axial 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 molding sand.
