[0042] Working principle: When the concentrator based on the intelligent control mixing and dosing device is used, the user first pours the slurry into the concentrating tank 1 through the feed pipe 45, and then uses the dosing component to add flocculant into the concentrating tank 1, and then starts the motor 31.
