Sand mixer of resin sand is the key equipment in determining the quality of molding sand. Because of its low automation, difficulty in parameter adjustment and incapability in effective supervision when operational processing, in this project, we transformed a sand mixer of large tonnage which used old contactor and relay control system. Through the transformation to PLC control system, application of real-time monitoring of liquid materials, and online management of the flow via feedback system with two-way wireless Ethernet data transmission, we achieved our aim to improve equipment automation, save cost, do real-time supervision and in addition, control the quality.
