so the relations of washed coal ash and ratio must be balanced, and technology reformation works of floatation system would be done to increase ratio and economic benefits.
建议要平衡好精煤灰分与产率的关系,并拟进行浮选系统的技术改造工程以进一步提高精煤产率及经济效益。
the results of the flotation experiments shows that the ash content of the washed coal is only half of the coal slurry flotation without comminution by high pressure water jet, and the total sulfur .
试验结果表明,高压水射流粉碎过的煤泥浮选后其精煤的灰分含量为煤泥直接浮选精煤含量的一半,全硫含量仅为煤泥直接浮选精煤含量的五分之一。
the brief introduction to the process flow and equipment of the newly built whole section sampler for washed coal in anshan iron and steel complex is given.
介绍了鞍钢新建洗精煤全断面采样装置的工艺流程、设备概况;
with improvement of the market situation, the price of washed coal maintains at a high level. the coal of these two layers is mixed washing with coal of other layers.
随着市场形势好转,精煤价格较高,这两层煤与其它煤层混合入洗,灰分、硫分都能满足用户的需要。
