Abstract
Embodiments of the invention include a dust extraction system including an array of two or more centrifugal dust removal devices, e.g., axial cyclones. The array of axial cyclones is configured to operate in parallel. The array of axial cyclones includes one or more sensor and a controller in communication with the sensor and adapted to receive air flow information from the one or more sensor. Inflow valves are operatively connected to the controller such that air flow through the array of axial cyclones is monitored and maintained at an optimum operating condition for each of the individual cyclones in the array. This is done, in general, by opening inflow valves as the air flow increases above a predetermined air flow value and shutting inflow valves as air flow decreases below the predetermined air flow value threshold.
