    Torque required for a sand mixer

    Thanks everyone. Thanks, I'll account for the minor frictional losses that way. I attached pictures of my calculations, I did make a mistake before, but I corrected it and ended up with a smaller torque requirement. It is not the vessel that is rotating, but the blades inside of the vessel...

    Torque required for a sand mixer

    Yes, it is pretty low, but that figure does not include drag from the sand or any frictional forces. Only the torque that it would take to accelerate the load up to speed in 5 seconds based on an overall moment of inertia. Also, it will be quite a small drum as it will only handle about 7.2kg of...

    Torque required for a sand mixer

    Hey guys! Thanks for all of your input. Actually using a kitchenaid mixmaster right now! I'm trying to automate the process and to mix larger batches. I should have mentioned, the drum will be stationary and inclined at an angle of 60 degrees from horizontal. The blades will rotate within...

    Torque required for a sand mixer

    Hi everyone,I am designing a mixer that will combine silica sand with a small amount of sulfuric acid and need to properly size a motor/speed reducer assembly for this application. The mixer will be run at an operating speed of 60 rpm. The blade configuration in the mixer will be similar to...
