Abstract: The digital control system of electromagnetic high frequency vibrating screen combines the technologies like computer，electronics，and network systems，which replaces the traditional potentiometer-type control.It can precisely control screening parameters and also significantly reduce the operation difficulty.The operator can control the entire screen machine on site，and also optionally set and verify the working parameters and the historical records of the electromagnetic screening system.A good man-machine interface makes the operation intuitive and simple.It is so widely used in mineral processing，coal concentration and brick preparation etc.The screening efficiency can be greatly improved，meanwhile，labor intensity be reduced and the management level improved.Its innovation is to achieve on-site control and remote centralized control，so the electromagnetic screen control level has been improved with great economic and social benefits.
