But we already build 2 machine one 25kg mixer and 80kg mixer both are working now.
In 25kg. Mixer we use 1.5 kw power with 71nm torque
In 80kg mixer uses 7.5kw, with 280nm torque.. Both are same mixing speed but dough qty only varied.
For both machine we selected motor and torque by reference...
We are using motor with gear box it will reduce the speed at 250rpm. Then torque will also increase. Max speed is 250rpm for mixing, it is enough. When increase the power then Increass torque also by using suitable gear box(it will convert 1440rpm to 250 rpm means 1:6 ratio) &
We using formula...
Blade start rotates from 0 to 250 rpm in 5sec.
That formula I had simplified whether it is right or not I don't know.
But blade will rotate uniform rotations but in some cases we need 2 speed for blade that is first 1or 2 min it may rotate at 150rpm after that will be rotate at 250 rpm. This...
That motor and gear box choosing by another catalogs.. And
I already using formula of T=I. a
I=mr^2, a=(n2-n2) /60*5.
In this formula am getting very less torque.
This is not correct.
I will take mass 25kg dough+15kg blade weight+10kg(water and ingradients) =50kg.
I need calculate the torque and power for mixing. Now I don't know the force exerted by blade because dough is gradually take more torque with respect to time(by friction) .
Here which formula we use for moment of inertia and acceleration.
In second paragraph I will give the power and torque...
Please help me...
Tell me how to find real torque for rotating spiral of dough mixer. We need to mix 25kg dough with adding water and Ingradients. Spiral made by ss rod of 25mm dia. Spiral dia is 250mm. Rotating speed is 250rpm(max). When start the machine rotate both spiral and bowl. Dough...
