Procedure for Cement Mill Shell Lifting 水泥磨筒体吊装方案 编制Made by: 审核 Verified by: 批准 Approved by: 二0一四年五月三日 May 3, 2014 水泥磨吊装方案 Procedure for Cement mill lifting 一、概述summary： φ5*15M型管磨机，其主要结构为进料装置、主轴承、回转部分、出料装置以及润滑装置五个部分。由于水泥磨是水泥厂的关键设备之一；其设备安装质量好坏将直接关系到全线生产能否正常运行。 φ5*15M type mill,mainly include feeding equipment, main bearing, rotary unit,discharging and lubrication equipment.As cement mill is one of the critical facilities in cement factory,equipment quality shall directly affect the normal operation of all fronts production. 二、水泥磨主要结构、技术参数Main structure and specification of cement mill 规格Specification Φ5*15M 驱动方式Drive type 中心传动磨center driving mill 生产能力production ability 150T/h 磨机转速 revolving speed of miller 14.5r/min 主电机功率power of main motor 6300KW 磨机支撑方式 support type of miller 双滑履double slide shoe 主轴承润滑方式lubrication type of main bearing 稀油集中润滑thin oil lubricate intensively 设备总重total weight of equipment 磨体重weight of cement shell 约590T about 590T 189T 起重就位Hoisting in place： 3.1吊装准备Preparation of lifting： 1、将四号磨房内场地回填、平整至室外同一高度，图1。同时将四号磨房门口钢梁拆除。Backfill the mill ground up to the same level as outdoor ground, fig 1. Meanwhile, remove the steel beam of mill 4# opening. (1) 将场地垫上钢板及枕木图2。 Lay the steel plate and sleeper(wood) on the ground.Fig2. （2） 3.1 水平牵引Level traction： 先在进料端搭设约1m高枕木用于支撑保护图3。 Put the sleeper around 1m high on the mill inlet side used as support protection. Fig 3. (3) 利用千斤顶，顶升进料端，将磨机1号与2号的支撑拆除图4及图5。 Use the jacks to hold and push up to the inlet position. Remove mill support 1 and 2. Refer to fig 4 and 5. (4) (5) 3、在距离磨进料端5m处，搭设牵引装置，如滚杆、拖排、枕木及相关用具，牵引部分为底板150mm加上滚杆108mm加上拖排250mm加上4根枕木高600mm，搭设高度约1m图6。Put pulling device 5m from the mill inlet position such as rolling bars, pulling wood, sleepers and relative tools. Traction part is comprised of 150mm
