通过对原煤准备系统工艺的优化,增加了系统的灵活性,可根据煤质变化采用合适的工艺:-8 mm分级筛筛下物既可进入原煤仓入洗,也可不入洗直接装仓与洗选精煤进行配装销售。经过优化,提高了精煤回收率,降低了洗选成本,实现了效益最大化。 Through the optimization of raw coal preparation system technology, increased system flexibility, according to the coal quality changes using the appropriate process: -8 mm grading sieve sieve can enter the raw coal warehouse into the wash, or not into the direct loading warehouse and Washed coal for distribution and sales. After optimization, the recovery rate of clean coal is increased, the cost of washing and washing is reduced, and the maximum benefit is achieved.
