  • Control system for a repulping apparatus
    Patent number: 6032885
    Abstract: A control system for a repulping apparatus having a vat containing a pulp and water slurry and a rotatable blade for mixing the pulp and water to form the slurry. A feed apparatus moves the pulp into the vat and a feed indicator senses the entry of the pulp into the vat and produces an entry signal indicative of the pulp entering the vat. A controller responsive to the pulp entry signal calculates the volume of water to be added to the vat and the water flow rate to provide a predetermined consistency in the slurry and produces a signal representative of the calculated volume of water. A water volume control receives and is responsive to the calculated water volume signal to control the admitting of water into the vat. The controller also produces a signal representative of the calculated rate of flow. A flow control is responsive to the calculated water volume signal and to the calculated rate of flow signal to admit water into the vat at the calculated rate of flow.

  • Adaptive constant refiner intensity control
    Patent number: 4661911
    Abstract: A method and an apparatus are provided for maintaining a constant refining intensity under varying tonnage rate and applied power conditions to a slurry of paper stock being passed through a disk type refiner. The system utilizes a control strategy and several unique control algorithms which combine to provide a result which relates the speed of rotation of the refiner elements to the power consumed by the drive motor. The present invention is based on intensity which is defined as the net refining power applied divided by the number of bar crossings (refining elements) per unit time. The system is an adaptive control system which operates on the basis of real time measurements of the refiner process.

  • Apparatus for controlling a variable speed gearmotor
    Patent number: 4589598
    Abstract: A refiner control continuously calculates required gearmotor output speed in opposition to the main motor drive power such that an increase in main power causes a decrease in gearmotor output speed and therefore provides a variable resolution over the entire power range of the main drive for stable refiner operation at various setpoint levels.
