双进双出钢球磨煤机直吹式制粉系统运行分析及研究

Steel Ball Coal Grinding Machine with Double lnlets and Double Outlets

介绍了美国Svedela公司双进双出钢球磨煤机的技术特点,该型磨煤机研磨能力强,可调范围广,响应迅速,但在合肥二电厂调试中,经常发生系统堵煤,影响该型磨煤机正常技术性能的发挥,究其原因,煤的全水分偏大,建议改变磨煤机入口结构。

Discusses the technical special features of Sredela steel ball coal grinding machine with double inlets and double outlets,points out this grinding machine features strong grinding capability,wide adjustable range and quick response,but the coal blockage occurred quite often in the system spoiled the normal performance of the grinding machine while it was being commissioned at Hefei No.2Power Plant,identifies the higher water content in coal as the cause for the blockage,and suggests structural modification at the inlets of the grinding machine.
