Each cylinder, control valve and motor operates as specified in the concrete mixing process. The control of each cylinder, control valve and motor must be accurate, stable, safe and reliable. The control system has two working modes, automatic and manual, and the relationship between them is independent and restricts each other. The internal system of the mobile concrete mixing plant has good anti-interference ability and perfect alarm signal self-protection function. By communicating with the computer, it can display the system running status and fault alarm signal.
