由哈尔滨国营第一五五厂和湖北化纤集团有限公司共同开发的立式连续过滤机、高效研磨机和细粉碎机等三设备于97年6月11日～12日在湖北化纤集团有限公司通过由中国纺织总会、航空航天部共同组织的鉴定。该三台设备自95年底在湖北化纤集团有限公司短纤生产线上试运行至今,设备状况较好。细粉碎机按R071粉碎机外形设计,采用静变频分别控制三辊的转速使其之间存在速度差异,加之特殊的锯齿结构,可保证碱纤维素的粉碎效果并可大幅提高工序能
Three sets of equipment, including vertical continuous filter, high-efficiency grinder and fine grinder, jointly developed by Harbin State-owned State-owned Factory and Hubei Chemical Fiber Group Co., Ltd. were approved by Hubei Chemical Fiber Group Co., Ltd. from June 11 to December 12, 1997 By the China Textile Federation, Department of Aeronautics jointly organized appraisal. The three sets of equipment from the end of 1995 in Hubei Chemical Fiber Group Co., Ltd. staple fiber production line commissioning so far, the equipment in good condition. Fine pulverizer by R071 mill shape design, the use of static frequency control of the three-roll speed control speed differences exist between them, combined with special sawtooth structure to ensure the crushing effect of alkali cellulose and can significantly improve the process
