棒磨机(中英文).docVIP

一、棒磨机的结构 一、The structures of Rod mill 棒磨机主要由以下几部分组成： The Rod mill is made up by several parts, as follow: 1、筒体部分：筒体上开有人孔，供检修和更换筒体内衬板时使用。 1. The tube part: there is a man’s hole in tube that used for examining and repairing and changing liner. 2、给料部分：供进料时使用。 2. The feeding part: used for feeding. 3、排料部分：供棒磨机排出合格产品时使用。 3. The discharging part: used for discharging proper product. 4、主轴承部分 4. Main bearing part. 5、传动部分 5. Driving part: 根据需要，棒磨机从传动形式上分为左旋和右旋，从排料形式上分为周边出料和中心出料两种，供货时按订货合同。 According to requirement of process line, rod mill is divided into the left rotary and right rotary .It depends on the contract. 二、棒磨机的工作原理 二、The Rod mill works principle 电机通过减速装置驱动筒体回转，筒体内的碎矿石和钢棒在筒体回转时受摩擦力和离心力作用被衬板带到一定高度后由于重力作用，便产生抛落和泻落，矿石在冲击和研磨作用下逐步被粉碎。被粉碎的矿石经排料部分排出筒外。供料机连续均匀地喂料，矿石经联合进料器连续均匀地进入棒磨机，被磨碎的物料源源不断地从棒磨机中排出。棒磨机是可以每天24小时连续工作的粉磨设备。 The motor drives the tube rotary by reducer, ore and steel rod can be thrown and rushed down by force of friction and centrifugal force to a certain height when tube rotaries ,and then ores can be crushed and grinded gradually. Crushed ore discharge by output part .The feeder feeds evenly, ore is fed by combine feeder continuously, the crushed ores discharge gradually .Rod mill can work continuous for 24 hours per day. 三、棒磨机的安装 三、The installing of Rod mill 棒磨机应安装在牢固的混凝土基础上。棒磨机的基础设计和施工请参看棒磨机总装图和基础图。为了保证使用过程中棒磨机各部件的位置精度不发生大的变化，棒磨机的基础应采用整块式结构。 The rod mill should install on steady concrete groundwork. The foundation designed and the construction looks at general drawing and foundation drawing. In order to make change of location accurate assembly small in use, the foundation of Rod mill adopts full piece structure. 混凝土基础耐压强度达到75%以上后即可在上面安装棒磨机。在安装之前应对基础的质量进行检验，要求混凝土没有影响强度的缺陷，预留孔的数量和位置符合要求，预留孔内无杂物和积水、无油污。采用“地线法”进行安装作业时，在基础上表面应预埋“中心标板”。安装前基础上画出所有中心线并在“中心标板”上做出醒目的冲点标记，作为安装时的中线基准。 If the compression resistance of concentrate foundation is more than 75%,the rod mill can be installed .Before installing ,the quality of foundation should be examine
