This powder filling machine, paired with a conveyor belt, forms a highly efficient and automated filling line. The equipment uses screw metering, achieving a filling accuracy of ±1g and a speed of 20-50 bags/minute. The conveyor belt automatically transports empty bags to the filling station, completes metering and filling, and then delivers them out, eliminating the need for frequent manual handling. The entire machine is constructed of 304 stainless steel and equipped with a dust collection interface, meeting the standards of the food, pharmaceutical, and chemical industries. It is easy to operate, with one-button start/stop, significantly reducing labor intensity and increasing production capacity, making it suitable for continuous quantitative packaging of various powder products.
