mixer propeller mech design
(OP)
I am currently designing an agitated vessel, that requires a propeller to suspend solids within water. The speed is 2.2 rev/s, and the diameter is 800 mm. How do i determine the mechanical aspects of the propeller, such as shaft diameter, pitch of the blade etc..
much apreciated to any help you can offer

agitatr design for suspending solids in liquids. We have been using this and have found quite useful.
For solid suspension you need to decide the scale of agitation (from 1 to 10). You need to know the densities of liquid, the soild and viscositiy of the liquid. There are graphs which will help you determine the parameter from where you can estimate the impeller dia, considering that the RPM is fixed.
Make sure that are well away from the critical speed.
Hope the above will help.

They have articles and a good software for the mixer's design.

The group of papers refered to above were written by the staff at Chemineer in the mid to late 1970's. They are informative, well written and supply the best practical guide to mixer/agitator design that I have ever found.
They are still available from Chemineer...... "Lightnin" also supplies a little design book explaining their products
Hope that this helps....

i mean
thickness of the shaft used in agitator
it is very urgent
please help me

Hi madhavan, you should give us mor detailedinformation if you want to get useful answers,for exmple. oif you wuse a rpm reducto, the size of the last shaft, (reduced rpm is a good indication of thew minimal diameeter the agitator sahfts has to be.
Pleaw e send more detailes Let me sugest to put a personal post about tjois you wil obtain more answers
