circuit. The load calculated from the strain indicator was found to be in good agreement with roll load found from the Robert''s formulation. entry and exit points. Here the rate of internal energy Keywords: Rolling mill, Roll load, Robert, strain gauges I. INTRODUCTION Rolls are the the most basic part in a rolling mill. Forces
Jul 01, 2009· I was thinking the same thing about the hammer mill with no load. We are spinning a really heavy roll (100k lbs.) with hammers that will swing out under centrifugal force and with no resistance except for windage and bearings. I have amp readings for the same mill running with no load for two different motors at 450 and 600rpm.
1 = Nip roll velocity E = Elasticity of the material A = Cross sectional area of the material The larger the elasticity (E), the less likely the material is to stretch. For most values of EA, use TORQUE CONTROL For stretchy material, where E is small, speed control can approach being as good as torque control

Feb 21, 2005· I can figure out all the HP required to move the rollers, chains, sprockets, etc.. but dont know how to include the palletload into acount. There is no "friction" per say as the load is "freerolling" on the rollers, but I still need to get it moving in 1 second, and then keep it moving. Let me know!
DuoDrive Talk about torque. Pinch roll reducers use one worm on the power input shaft to turn two gears simultaneously, in opposite rotations. Pinch roll reducers are designed for applications such as coldroll forming, tube mills and wire mills, where very high torque is needed to smoothly propel metal through high pressure mill rollers.
The load on bearings used in machines under normal circumstances will, in many cases, fluctuate according to a fixed time period or planned operation schedule. The load on bearings operating under such conditions can be converted to a mean load (Fm), this is a load which gives bearings the same life they would have under constant operating ...
Oct 14, 2008· Selecting speed reducers for roll forming lines ... After the number of roll stands and the overall horsepower required are ascertained, the next step is to determine the amount of horsepower applied to each reducer. ... Figure 2 A typical reducer rating table includes horsepower ratings, efficiency, and output torque. This particular reducer ...
