ABSTRACT:
A method of operating a sand screw comprises: sensing speed of a sand screw delivering sand; determining a corrected delivery rate of sand, including converting the sensed speed of the sand screw into the corrected delivery rate of sand in response to predetermined sand screw delivery rate conversion data; and controlling the speed of the sand screw in response to the corrected delivery rate of sand. The sand screw delivery rate conversion data is based on first and second order polynomials defining the relationship between conventionally determined indicated sand screw delivery rates (i.e., using sand screw speed and a selected calibration factor) and actual delivery rates based on measured sand output.
