基于弛张筛对动力煤的深度分级作用，阐述了动力煤深度分级后对生产工艺的优化，提出了分选动力煤的新工艺。对于全级入选的动力煤选煤厂，一是解决了煤泥减量化生产瓶颈，避免大量煤泥造成的后续处理问题，二是实现了末煤可以灵活地选择进入块煤分选系统分选或末煤分选系统分选，三是实现了粉煤可以灵活地选择进入水洗系统分选或直接作为末煤产品；对于仅入选块煤的选煤厂进行原煤深度分级后，降低了块煤分选下限，增加了块煤入选量，解决了动力煤〈25 mm 粒级煤不能进入重介浅槽分选机分选的技术难题。
基于弛張篩對動力煤的深度分級作用，闡述瞭動力煤深度分級後對生產工藝的優化，提齣瞭分選動力煤的新工藝。對于全級入選的動力煤選煤廠，一是解決瞭煤泥減量化生產瓶頸，避免大量煤泥造成的後續處理問題，二是實現瞭末煤可以靈活地選擇進入塊煤分選繫統分選或末煤分選繫統分選，三是實現瞭粉煤可以靈活地選擇進入水洗繫統分選或直接作為末煤產品；對于僅入選塊煤的選煤廠進行原煤深度分級後，降低瞭塊煤分選下限，增加瞭塊煤入選量，解決瞭動力煤〈25 mm 粒級煤不能進入重介淺槽分選機分選的技術難題。

Based on the application of flip-flow screen in deep classification of steam coal,the optimization of process was introduced. For the coal preparation plants which prepared the whole grade steam coal,the application decreased the slime production,made the fine coal separate in lump coal separation system or fine coal separation system flexibly,let the pulverized coal go into water wash system or be sold as fine coal. For the coal preparation plants which only prepared lump coal,the application reduced the lower limit of separation,increased the separation amount of the lump coal,realized -25 mm steam coal could be separated by dense medium shallow slot cyclone.
