摘要
利用长江沿岸低品位石英砂开发研制保温隔热砖,研究球磨参数对低品位石英砂粒径的影响,为制备高性能的保温隔热砖奠定原料基础。研究结果表明:随着球磨时间的延长,石英砂粒径减小;随着球磨转速的增加,石英砂粒径逐渐减小;随着球磨机装料量的增加,石英砂的粒径增加;随着球比的增加,石英砂粒径逐渐增加。综合考虑整个工艺过程性价比,确定最佳球磨参数为:球磨时间为60min,球磨转速为300r/min,球磨机装料量为200g/L,大小球质量比值为0.75。
The insulating brick was prepared with the low grade quartz sand along the Yangtze River, and the effect of ball milling parameter on the grain diameter of low grade quartz sand was studied, which lay a material foundation for fabricating high performance insulating brick. The results show： the grain diameter is decreased with the prolonging of the ball milling time and the increasing of the ball milling speed, but is increased with the increasing of the charge weight of the ball mill and the ratio of large balls to pellets. The optimal powder can be obtained when ball milling for 60 minutes at 300r/min with the charge of 200g/L and the large ball/pellet mass ratio of 0.75.
