Does any one has any formulas of any method of calculating the power and torque requird

Please help!!

If you instructor bored to death?

problem is you have not mentioned

chain size

chain length in total

weight of the chain and buckets

the desired speed of conveyor drag chain

get the weight of the entire business and then find a gearbox capable of moving it at a speed that is not rediculous and then:

then you can find the electric motor that will do the job

Your resistance to motion are: stone to steel friction at the line pan floor, stone to steel friction against the sidewall(S) and steel to steel friction of the chain against the line pan floor. For the middle one we calculate the pressure as the equivalent hydraulic pressure, because we're lazy beggars, whereas t'other 2 are simple self weight downloads. If you take the download of burden on the conveyor flights etc you will err on the light side, so ignore the interaction & take the separate loads mentioned.

Your further work is then a straightforward drive selection. Torque is irrelevant for the calculation of drag forces & is only determined by your eventual sprocket diameter.

For more comprehensive advice Google the Renolds Chain website, or similar.■
