摘要采取加大冷风阀开度、提高磨内通风量及冷风比例等技术措施，降低了开路磨出磨水泥温度。技改后，出磨水泥温度降低约30℃左右，初凝时间和终凝时间分别延长约23min和31min，磨尾滑履轴承温度由58℃~60℃降低至50℃~53℃，磨尾收尘器入口负压提高150Pa左右，电耗相应增加0.5kWh/t水泥，水泥性能大幅提升，设备运转率提高。

Abstract: The technical measures such as increasing the opening of cold air valve, increasing the ventilation volume and the proportion of cold air in the mill were taken to reduce the cement temperature of the open circuit mill. After the technical transformation, the temperature of cement out of the mill is reduced by about 30℃, the initial setting time and final setting time are extended by about 23 minutes and 31 minutes respectively, the temperature of the bearing of the sliding shoe at the grinding tail is reduced from 58℃~60℃ to 50℃~53℃, the negative pressure at the inlet of the dust collector at the grinding tail is increased by about 150 Pa, and the power consumption is increased by 0.5 kWh/t cement, the cement performance is greatly improved, and the equipment operation rate is improved.

Key words: open circuit mill cold air valve opening cement temperature setting time slide shoe bearing temperature
