Among them, dispersants and stabilizers are indispensable. The additives are closely related to the properties of raw coal and water.

[0003] Existing coal-water slurry additive raw material mixing devices, such as the neutral coal-water slurry additive production raw material mixing device disclosed in utility model patent application number 202121293168.8, mainly include a mixing tank. A motor is connected to the top of the mixing tank. A rotating shaft is connected to the output end of the motor. A connecting rod is connected to the rotating shaft. A connecting ring and a connecting ring are connected to the connecting rod. Several stirring rods are evenly connected to the connecting ring. In use, the sealing cover is opened, and different neutral coal-water slurry additive production raw materials are put into the mixing tank through the feed inlet. After feeding is completed, the sealing cover is closed, the external power supply is connected, and the motors are started.
