Automatic control method of high-pressure roller briquetting machine

The invention relates to an automatic control method of a high-pressure roller briquetting machine, which is used for conducting remote automatic control on a screw feeding motor, a fixed roller motor, a movable roller motor, a hydraulic station, lubrication of a movable roller speed reducer, lubrication of a fixed roller speed reducer and lubrication of the bearings of the fixed and the movable rollers. The automatic control method can guarantee the safe and reliable operation of the high-pressure roller briquetting machine and a set programmable logic controller (PLC) program controls the start and stop of the motors as well as the opening and closing of a solenoid valve of the hydraulic station. The PLC and a touch screen can control the hydraulic station, the lubrication of the movableroller speed reducer, the lubrication of the fixed roller speed reducer and the lubrication of the bearings of the fixed and the movable rollers. The panel of the touch screen can display the operation state, failure state,
