近日,川煤集团达竹公司渡市选煤发电厂一项洗煤设备改造获得成功,每年可多创效益100余万元。2014年以来,渡市选煤发电厂注重深挖内潜提效益,大力开展技术创新活动,将目光瞄准了洗煤设备中的振动筛,决定对其进行技改,以降低精煤泥灰分。振动筛是洗煤生产中的关键设备之一,川煤以前使用的振动筛具有几个缺点:一是精煤灰分太高,一般都在13%~15%,影响综合精煤回收率;二是故障率高;三是铺在筛板上的筛网使用寿命短、费用高,
Recently, Sichuan Coal Group Tatsu Corporation Du Town Coal Preparation Plant coal washing plant transformation success, more than 100 million yuan each year to create more benefits. Since 2014, the city’s coal preparation plant has paid special attention to the potential benefits of deep excavation, carried out technological innovation activities and set its sights on the shale shaker in the coal washing equipment. The technological transformation was decided to reduce its ash content. Shale shaker is one of the key equipment in the coal washing production. The shale shaker previously used by Sichuan Coal has several disadvantages: First, the ash content of the fine coal is too high, generally 13% ~ 15%, affecting the comprehensive coal recovery rate; secondly, The failure rate is high; Third, the screen laying on the sieve plate life is short, high cost,
