Would like to know how to calculate which hydraulic motor to turn a 2-1/2 dia shaft at a length of 30",with 15 mounted rotating chewing disks for a shredder machine. We are shredding soils and clay at about 40 yd3/hr. we are also using a No. 80 drive chain on 12 to 19 tooth sprocket too. Soils are about 80lb/ft3 density Any ideas welcome. Thank you
I don't know enough about soils to know the power requirement from what you have said. But if you look at the strength of the chain, and the required RPM to be able to process the volume, then that will give you a pretty good upper bound on motor power. Power is torque times RPM (with units corrected to make it all come out right)
At the right side there is a "Internal combustion" Take a look at exhaust stroke. http://www.grc.nasa.gov/WWW/k-12/airplane/shortp.html
