Research Abstract

To operate a two-roll mill continuously in batch processing, a system which can regulate automatically the clearance between the two rolls is proposed. The system consists mainly of a dial gauge, a photointeitupter, an A/D converter, a microcomputer, a control module, a driver, a pulse-motor and a toothed wheel. The dial gauge is set on the outer surface of the rolls. The photointerrupter connected to the gauge detects the variation in clearance and the output signal is provided to the microcomputer through the A/D converter. The perfon-nance program calculates the difference in clearance between the measured and the expected values and sends an input signal to the control module. It transmits a pulse signal for motion command to the driver, which in tum makes the pulse-motor rotate. Finally, the clearance is slightly regulated by the action of the toothed wheel attached to the axes of the pulse-motor and roll bndle. We also -carried out experiments in the dispersion of fly-ash particles to confirm the dispersion philosophy of the proposed control system. 'Me results show that the system can operate satisfactorily as expected.
