The given Batching system calculates the motor speed or the motor speed of each quantitative rotor pump based on the ratio of each material. The weight of the materials is detected by the weighing module, and the actual material flow is calculated based on the speed signal and the weight signal. The output of the PID regulator controls the frequency converter, thereby changing the speed of the disc motor or the quantitative rotor pump motor, in order to control the material flow to reach the set value. When 90% of the pre-defined component materials are reached, the system automatically switches to slow feeding until the material parameters set by the pre-design are precisely reached. The feeding and feeding system follows this pattern. When the subsequent feeding is also completed, the weighing instrument displays the total weight value at this moment. During this process, the weight values of each material are also displayed separately. Then, the system automatically opens the discharge door and simultaneously starts the conveyor at the bottom of the batching unit to transport the materials to the next unit or for batching.

The batching system uses rotor pump feeding and automatic metering control. A weighing module is installed under the material tank to monitor the batching weight. When the materials added to the tank meet the formulation requirements, feeding stops automatically and the conveying is shut down automatically. A closed-loop Weighing system is formed by a computer and a frequency converter. The computer compares the size of the weighing instrument with the given flow signal and controls the frequency of the frequency converter to control the speed of the conveying pump, thereby controlling the flow. This allows for controlling the proportion of the ingredients entering the mixing tank. A temperature transmitter is installed in the mixing tank, and a cooling water pump draws water to cool it. The water flow is controlled by the frequency converter, and a closed-loop temperature regulation system is formed by the calculation, to control the outlet temperature of the materials. Temperature and preheating steam electric valves are installed in the material tank. Each temperature closed-loop regulation system is formed by calculation to control the material temperature. The pressure and temperature at this point are monitored. The speed of the conveying pump is controlled separately by each frequency converter. Each material tank is equipped with a stirring pump, and each stirring pump and the conveying pump are connected to the power supply through thermal relays, contactors, and air switches to protect and control the motor. The engagement and release of the contactors are controlled by the computer.
