The mixing tank according to the purpose can be divided into two types: the chemical stirring tank and the slurry stirring tank. The chemical stirring tank is used for various chemical preparation operations, and the material and structure of the stirring tank are also different depending on the nature of the chemical. At present, there is no fixed series of special acid and alkali resistant stirring tanks, and the volume of the stirring tank is selected according to the preparation system of the medicament. The slurry agitation tank is used for slurry mixing before the flotation operation, so that the slurry is fully mixed with the medicament to create conditions for the sorting operation. If some of the agents are added to the mill or to the sand pump pool and distributor before the flotation, there may be no agitation tank. The slurry agitation tank can be divided into two types: press-in type and lift type according to different structures. The agitating grinding tank has both agitating effect and lifting effect, and the lifting height can reach 1.2m. If the slurry self-flow height difference is insufficient and the difference is different in the equipment configuration When you are young, consider using this device.
The volume of the agitation tank is pressed and calculated:
V=[K 1 Q(R+1/Ï)t]/60
Where V-stirring tank volume, m 3 ;
Q-The amount of design flow (including return amount) entering the agitation tank, t/h;
R-slurry liquid to solid weight ratio;
Ρ-ore density, t/m 3
K 1 - treatment imbalance factor, when the ball mill is used before flotation, take K 1 =1.0; when it is self-grinding before flotation,
Take K1=1.3;
T-stirring time, min. Determined by the test, if there is no data, it can take t=3~5min.
