| 摘 要： | 在提出间隙级配模型的基础上，用QQ4A／B轻型球磨机和PSI-200拍击式标准振筛机，分析了煤料粒度为0．1～1．0，0．3～1．25mm，m（钢珠）：m（煤）=8：1～12：1，研磨罐转速为90～110r／min，研磨时间为15-60min条件下，钢珠添加种类对研磨效率的影响；并用DV-1＋PR0黏度计测试了浆体黏度．结果表明，用直径间隙法可以获得较高浓度的水煤浆，其中钢珠添加种类为R1：R2：R3=1：0．414：0．291模式下水煤浆浓度较大．

| Abstract: | Based on the interstitial position gradation model, by using QQ4A/B ball miller and PSI-200 standard sieve, under the size range of 0.1-1, 0.3-1.25 mm, ratio of grinding media to material is 8： 1- 12： 1, ball milling rate is 90-110 r/min, ball milling time is 15-60 min, the effects of various gradation model for ball milling efficiency were studied. Using DV-I ＋PRO digital viscosity meter inspected the slurry viscosity. The results show that the high concentration CWS can be fabricated by using interstitial position method, the R1/R2/R6 model is better. |
