Abstract:
An apparatus for controlling the supply of material to a processor that emits a material demand signal, the apparatus comprising:a material grinding and material particle sizing mill connected in material delivery responsive association to a processor emitting a material demand signal, said grinding and sizing mill including a plurality of controlled components; a control microprocessor responsive to, and operatively connected to, said material demand signal and to each of said plurality of controlled components, said control microprocessor configured to interpolate at least one operational parameter for each of said plurality of controlled components based upon said material demand signal and a plurality of feedback signals received from said plurality of controlled components to operate said grinding and sizing mill to deliver material for said processor, to grind the material, and to release material of a predetermined particle size to said processor from said grinder; wherein said plurality of controlled components includes: a mill conveyor drive motor, said drive motor actuating a material delivery system to deliver material to said mill for grinding; a mill grinder motor, said grinder motor driving a grinder to receive said delivered material and to pulverize said received material; a mill spinner motor, said spinner motor driving a centrifugal separator to classify pulverized material according to size; a temperate air inlet regulator configured to regulate a flow of temperate air into said grinding mill; and a heated air inlet regulator configured to regulate a flow of heated air into said grinding mill.
