If the voltage drop across the dust layer becomes too high, several adverse effects can occur. First, the high voltage drop reduces the voltage difference between the discharge electrode and collection electrode, and thereby reduces the electrostatic field strength used to drive the gas ion-charged particles over to the collected dust layer.

ABB drives in mining | 9 Applications Pumps Energy consumption is the most critical factor of a pump's total life-cycle costs. About 20 percent of a mine's total energy consumption is used by pumps. Flow and pressure control The flow and pressure of pumps need to be controlled due to fluctuations in process demand and system parameters.
