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.

为了使双辊轧机在批量生产中连续运行，提出了一种自动调节两辊间隙的系统。该系统主要由千分表、光电转换器、A/D转换器、微机、控制模块、驱动器、脉冲电机和齿轮组成。千分表设置在辊的外表面上。连接到测量仪的光断续器检测间隙的变化，输出信号通过A/D转换器提供给微型计算机。性能程序计算测量值和预期值之间的间隙差，并向控制模块发送输入信号。它向驱动器发出运动指令的脉冲信号，驱动器驱动脉冲电机转动。最后，通过连接在脉冲电机和辊束轴上的齿轮的作用，稍微调节间隙。我们还进行了实验，在粉煤灰颗粒的分散，以确认所提出的控制系统的分散哲学。“我的结果表明，该系统可以按照预期令人满意地运行。
