A variable speed conveyor or moving sidewalk has rows of spaced non-cylindrical support elements with belts supported thereon and driven at successively variable speeds from row to row. The belts provide plane moving paths and are driven by pinions on a drive shaft for each row. Spacers are arranged between belts and between support elements below the upper surface of the belts to fill …

The Model BSD is a "traction action" motion control that indicates when a conveyor belt has slowed or quit moving altogether. The unit can be adjusted as an overspeed, underspeed, or zero speed control. The output of the Model BSD can be wired into a PLC or DCS, or to the optional RMS controller (or MSD controller) which has a DP/DT relay to ...

Speed Monitoring for Conveyors Jasdip Pty Ltd 2 Once the conveyor is at full speed, any slip of more than 10% for a short period is grounds for shutting down the conveyor. In closed loop control systems, drive pulley slip will force more torque from the drive train as the control system calls for more torque to speed up the lagging belt speed.

The operations of belt conveyors can be distinguished into two groups: the stationary operation and the transient operation .The stationary operations include three cases: the case where the belt is totally stopped, the case where the belt is running at nominal speed with the steady state, and the case where the belt is running at a fixed non-nominal speed caused by speed control.
