An idea for efficient mixing
We decided to rotate the vertical drum about one of its perpendicular axis. This helps in having a tumbling of compost mix and resulted in a better mixing. We experimented this on a small scale where we used a pipe with holes as small size composter.
After doing some calculations and force analysis. I came to know that the shaft torque required to lift and rotate such an unbalanced mas is very high. This increases the power rating s on the induction motor. Which in terms increases the capital cost
The concept of the peripheral drive…
So I came up with an Idea for driving the drum with a peripheral contact drive. Thus the torque required for was reduced due to the diameter ration.
For this, I Designed a drum held between two rims of 1m diameter and are rotated by driving wheels at the periphery. This helps in having a small power rating motor since torque required is also less.
