<p>The process takes place in a kneader fitted with stationary teeth and a shaft also fitted with teeth, performing a rotary movement combined with a forward-and-back movement, and also comprising motor-driven valves controlling the exit of the carbon paste. …<??>At each cycle of rotation of the shaft a measurement is made, by sampling, of the current absorbed by the motor at certain specific positions of the shaft in its forward-and-back movement, the current is compared to a target value which may be corrected as a function of the level of this current in relation to predetermined thresholds, and this corrected value is introduced into a controller which determines the degree of opening of the outlet valves at each cycle. …<IMAGE>… </p> |
