摘要
为解决城郊选煤厂分级筛筛孔堵塞、跑末而导致的粒煤产品限下率超标的问题,研发出适于8 mm粒煤产品分级的HW12筛板。现场应用结果表明：HW12筛板筛分效率达到86%~91%,堵孔率低于10%,筛板使用寿命在6个月以上,从而有效解决了粒煤产品限下率超标的问题。
To control granular coal undersize fraction caused by screen aperture blocking of sizing screen in chengjiao coal preparation plant, HW12 screen plate is researched and developed, which is suitable for coal sizing at 8 mm. The application shows that the screening efficiency of this plate is up to between 86% and 91% , with less than 10% aperture blocking ratio and more than six month service life. It has improved efficiently granular coal undersize fraction.
