93年以来 ,南屯矿选煤厂根据矿厂情况 ,在原煤准备系统增设了末煤筛分系统 ,调整产品结构 ,取得了明显的经济和社会效益。 2 0 0 1年 ,与新乡威达振动机械厂共同开发出替代进口香蕉振动筛的双层等厚分级筛 ( 2 WZD2 4 6 7等厚分级筛 )。它的使用实现了全部筛分入洗 ,在降低洗水浓度、提高入洗能力和减少煤泥量等方面取得了显著效果。
Since 1993, the Nantun Coal Preparation Plant has added a terminal coal screening system to the raw coal preparation system to adjust its product structure and achieved obvious economic and social benefits. In 2001, we developed a double-layer, equal-thickness classifier (2 WZD2 4 6 7 equal-thickness classifier) instead of imported banana shale shakers jointly with Xinxiang Vida Vibration Machinery Factory. Its use achieved full screening into the wash, reducing the wash water concentration, increasing the ability to wash and reduce the amount of slime and achieved remarkable results.
