Can you tell me how to design a simple mixer for mixing solids and liquids? The specifications: Tank total capacity is 220 liters; diameter is 1,000 mm by 1,200 mm; liquid for mixing 150 liters (120 liters and solids 30 kGS); 60 RPM.
Can you suggest a shaft diameter, the type of agitator/anchor/blade and capacity of the motor?
Have an insight or suggestion?

3 June 2010 at 1:29pmI am not sure from the description of the process why you want to use an anchor impeller, but it can be done. An anchor impeller does not do a good job of suspending solids, so the solids you have must settle very slowly and remain suspended for perhaps as long as 10 minutes.
Making some estimates for the slurry properties, especially the viscosity, an impeller diameter of 900 mm should work. A typical blade width would be 90 mm with two vertical anchor blades. At 60 rpm a 1.5 kW motor and a 25 mm diameter shaft should be adequate.
