    Remember the equation of torque = tension x radius is linear, so torque must be decreased (for unwinds) and increased (for rewinds) at a linear rate relative to roll radius For example, if you start with a 175 inch roll radius (35 inch diameter) and unwind down to a 175 inch core radius (35 inch diameter); 175 divided by 175 is 10:1 ratioA roller chain is a series of connected journal bearings that articulate as they enter and leave the sprockets This articulation results in wear on the pins and bushings As material is worn away from these surfaces the roller chain will graduallyUnderstanding Roller Chain Wear Life | The DiamondTo increase the efficiency of your tube mills, Magotteaux developed the widest range of liners and diaphragms With more than 7,100 tube mills equipped all over the world, you will benefit from the best experience in the cement industry Our focus: reducing energy consumption and optimizing performance!
