The mixing system adopts the dynamic metering precision control mode, the effective signal of fast feeding and slow feeding starts the material pump to start the fast feeding process (that is, open two feed valves at the same time), tracks and reads the signal of the weighing sensor, and turns off the fast feeding signal when the weight is close to the preset large feeding value, so that the system enters the slow feeding process (close a valve). At the same time, the instrument tracks and reads the signal of the weighing sensor, and the instrument will judge whether the weight of the hopper is greater than or equal to the material target value. If it is greater than or equal to the instrument closes the small feed signal, stops the feeding process (all valves and feeding motors are closed), and the measurement ends.

Weighing mixer is a new material obtained by mixing different kinds of powder objects according to different weight ratios. The weighing mixer has three layers of batching buckets, the lower layer is 4 discharge buckets for weight, the middle layer is 4 batching buckets, and the upper layer is 2 upper hoppers. From the upper and middle hopper, the materials are respectively placed into four set weight discharge hoppers, storing four different types of materials, and then unloaded onto the discharge spiral at the same time, so as to obtain mixed powder materials of different gravity, that is, the entire batching process is completed. Electrical control feeding and dosing and discharging system, divided into manual control or adjustment and automatic control, these two working methods are available. The working process of the system: (1) The working process of the mixer: when the weighing module detects the lack of material in the material hopper, the feeding screw motor starts and runs; when the loading vibrator and the feeding motor start and run at the set time, all the working motors will stop only when the weighing module detects that the material hopper is full; (2) batching and unloading system working process: When the weighing sensor detects that the transfer vehicle is in place and determines whether the measurement of the hopper scale reaches the set value, the material can be discharged. If the measurement of the hopper scale fails to reach the set value, the batching motor will start, the feeding valve will open and the batching vibrator will start, and the material will be fed to the hopper scale until the set value is reached. Then directly into the unloading process. Each working process has a delay time setting, if it is a fully automatic control working mode, the first mixing machine process work, after the batching, unloading system process work.
