The working principle of the powder coating mixer is relatively simple. When the coating raw materials are added to the mixing drum through the feeding port, the control system starts the motor to drive the mixer to rotate at high speed. The agitator pushes the paint raw materials towards the barrel wall during rotation, and then rebounds back from the barrel wall to the agitator. This repeated cycle creates strong convection and shear effects on the paint raw materials in the mixing barrel, achieving uniform mixing. When the mixing reaches the preset uniformity, the control system turns off the motor, opens the discharge port, and discharges the evenly mixed coating.
