我选煤厂是一座年处理能力为240万t的大型选煤厂,最初设计的选煤工艺为跳汰主再洗,煤泥浮选,尾矿压滤联合流程。主要生产十四级炼焦精煤,灰分小于12％,水分小于12.5％。后因煤炭市场发生变化,为适应市场需求,增设了重介精选系统,精煤灰分定位在9.5％以下,但产品水分仍按12.5％考虑。近年来,随着煤炭市场的竞争日趋激烈,用户对煤炭产品的质量要求越来越严格。因为有重介分选把关,我厂的精煤灰分、硫分及杂物等主要指标一直比较稳定,用户对此也非常满意。唯一的缺憾是精煤水分偏高,不但造成运力的浪
Our coal preparation plant is a large coal preparation plant with an annual processing capacity of 2.4 million tons. The coal preparation process originally designed is a combined process of primary re-washing, slime flotation and tailings pressure filtration. The main production fourteen coking coal, ash less than 12%, less than 12.5% moisture. Due to changes in the coal market, in order to meet the market demand, a heavy medium selection system was added. The fine coal ash content was below 9.5%, but the product moisture was still 12.5%. In recent years, with the increasingly fierce competition in the coal market, users have become more stringent in the quality of coal products. Because there are heavy media separation checks, I plant the ash, sulfur and debris and other major indicators have been relatively stable, users are also very satisfied with this. The only drawback is the high water content of coal, not only caused the wave of capacity
