Motor Capacity Selection

Good homework or test question?

Well, 2000tpd is _{<tap, tap, press equals>} 23.1kg/sec.

200m long at 45deg inclination is _{<tap, tap, press equals>} 141m of lift.

So the conveyor needs to supply _{<tap, tap, press equals>} 3.21e5 Nm/s to the materials.

Double it, say, to allow for friction, so a motor in the region of 6.2e5 Nm/s power should be a reasonable first stab.

PWSlack, you are giving him false hope... you left out a lot of tap, tap, tapping.

For example: Speed, gear ratio and belt capacity? No mention of any of that in his OP, so that could be a 10ft wide belt running slow with a small motor and a big gear reduction, or a 6 inch wide belt running incredibly fast with direct drive, either of which will affect the motor size as well.

Respectfully, that is the original poster's problem to work out, outside the question asked in the original post. Irrespective of the width of the belt and its gear ratio, the puissance needed to transfer the load at that rate will be about the same order of magnitude whatever the mechanical arrangements.

I knew, that was more for the benefit of the OP so he would further realize your intent in pointing out the incomplete nature of his query. I should have used a smiley so you would not have deemed it a slight on you, but when I post from my iPad, smilies are disabled. Sorry.

Is it the conveyor that has 45° slope, or the hopper sides?
