Abstract (en)

[origin: US4598872A] The invention relates to grinding apparatus and a method of operating such apparatus in which the gas speed in the nozzle ring of the mill is altered as a function of the power consumption of the bucket conveyor so that the quantity of material conveyed by the bucket conveyor and the gradation of grain sizes thereof are kept constant. A control circuit alters the material supply to the mill when the gas speed in the nozzle ring exceeds a predetermined maximum value or falls below a predetermined minimum value.
