ABSTRACT:
Carbon black is introduced into a granulating machine 3 through an inlet 1 and water is introduced into the same through an inlet 2 to prepare granulated carbon black, which is fed to a cylindrical rotary type dryer 5 through a line 4 and is dried. A product of carbon black is discharged through a line 6. Temperature in the dryer 5 is measured by a plurality of thermometers 10. A combustion control device performs the arithmetical processing of temperature data to obtain the initial point at which the state of the carbon black is changed from the constant rate of drying to the falling rate of drying. The control device controls each flow rate of fuel supplied from each line 7 or 8 to burners 9 for the front and rear half portions of the dryer by using the critical point and the temperature of the carbon black at the outlet of the dryer, whereby a temperature profile for the carbon black in the dryer 5 can be made stable for a long time.
