Torque is a vector quantity. The direction of the torque vector depends on the direction of the force on the axis. Anyone who has ever opened a door has an intuitive understanding of torque. When a person opens a door, they push on the side of the door farthest from the hinges. Pushing on the side closest to the hinges requires considerably ...

The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge. C = distance of centre of gravity or charge from centre of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in RPM. HP = A x B x C x L. Where.

3 Answers Sorted by: 3 I've built 2 motorized grain mills. The first used a 600w (input power) 3/8" drill. It worked well enough with a loose crush (") but I ended up frying the drill when trying to crush at ", so this is a good candidate to gauge the minimum torque. A 600W drill produces about 380W mechanical output.

Bolded word mine. These calculations are all correct. It's a little strange that you specified the rpm and not the tangential velocity.

If you know the maximum torque rating of your spindle motor, T max, it is easy to calculate the max cutting force using the formula below, where T max is in inchlbs, and r tool is in inches. If the maximum cutting force calculated from the spindle torque rating is higher than from the maximum power rating, then we will use that value.

If feed is valued at 300 per ton and the shrink (loss) is %, the cost of the shrink would be 300 x .0081 = per ton. If the feed mill produces 6,000 tons per week, the shrink loss value at per ton would be 14,500. That is significant, and that is why shrink must be measured and managed to keep it at a minimum.
