Speed control of belt conveyors during transient operation ...
Nov 01, 2016& 0183;& 32;The approach of speed control is an important one. In general, the belt conveyor is running at its nominal steady state speed and the average utilization of belt is less than the design capacity. This can be caused by temporarily or cyclic variations in the bulk material flow discharged on the conveyor or to allow for surge flows.Cited by: 19
Applying Adjustable Speed Drives to Conveyors
Most types of adjustable speed drives will regulate speed to so that the operating speed drops no more than 5% of the maximum speed when the load increases from no-load to full-load. Many drives offer 3% regulation or even 0.5% regulation as standard and have …
Efficiency of belt conveyor as function of belt speed ...
Coal flows in mines feature randomness. For this reason, it is reasonable to enhance efficiency of belt conveyors through coordination of belt speed and size of coal feed to be transported. The speed regulation quality of different control algorithms is evaluated. For the purpose of discontinuous control, the conveyor load factor is estimated.
