Can you provide guidance on mixer design for an agitator mounted on a tank with these dimensions: Tank: diameter = 8 m, height = 5.5,capacity = 250 m^3, material = mild steel (rubber lined), type=open, input/output = 260 m^3/h Liquid: slurry, solid = iron ore, solid 40% to 60%, grain size = 0.3mm, gravity = 2.93 t/m^3, temperature = ambient, abrasive = 1200-1400 g/ton agitator purpose = to prevent sedimentation at the top

Re: Can you provide guidance on mixer design for an agitator mounted on a tank with these dimensions?11 July 2011 at 1:29pmThe following is a rough guide to the required mixer design. A qualified mixing equipment manufacturer should be consulted for detailed answers, since specific weights and features will be different depending on the equipment source.
- Motor Power 150 KW
- Shaft Diameter 175 mm
- Shaft Length 4.9 m
- Impeller Type 4-blade, 45 deg angle pitched-blade impellers
- Number of Impellers 2
- Shaft Speed 30 rpm
- Gear Reduction for 1,800 rpm motor 60:1
- Gear Reduction for 1,500 rpm motor 50:1
- Reducer Torque 47,500 Nm
- Mounting Design
- Axial Load - Requires weight of gear reducer, impellers, shaft, etc.
- Torque 120,000 Nm
- Bending 92,000 Nm
