#### Modeling the Dynamics of Fabric in a Rotating Horizontal Drum Using the ...

This model is essentially a ball mill. The simulations are used to investigate fabric bundle kinematics, the power required to drive the rotating drum, and the power dissipated through normal and tangential contacts. ... For example, the specific drum power increases by a factor of 600% to 800% as the fill percentage decreases from 75% to 25% ...
