Mixer diameter - 1.0m diameter impellerThe impeller needs to be an axial flow impeller, like a 4-blade, 45-deg, pitched blade impeller. The tank must have tank baffles to prevent swirling and to lift and circulate particles. Typical baffles: 4 plate type baffles, each 0.4m wide and approximately the length of the straight side.
Rotational speed: 45 rpm
Shaft diameter: 51mm
Power required: 1.0 kW, 0.75 hp
A bottom shaft support is not required for natural frequency (critical speed), but a bottom support will reduce the required shaft diameter to 38 mm.
