Together with extensive mining experience and a wide portfolio of life cycle services, ABB is well positioned to tackle the industry''s most demanding situations. Automating the future Recent years have seen a significant increase in the level of automation and, in particular, the use of low voltage AC drives within the mining industry.
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 ioncharged particles over to the collected dust layer.
a constant DC bus voltage as input and produces a 3phase variable output voltage with variable frequency, the AFE uses the 3phase line voltage as input and produces a constant DC bus voltage. The AFE control is set to regulate unity or even a leading power factor. This can be used to minimize voltage fluctuation in the
ABB drives in mining | 9 Applications Pumps Energy consumption is the most critical factor of a pump''s total lifecycle 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.
The term refers specifically to electronic drives controlling the speed of AC motors – by adjusting the frequency and voltage delivered to the motor. Most commonly, the terms VFD and VSD are interchangeable. VVVF. The term VVVF is often used in the mining industry – it refers to a variable voltage variable frequency drive.
