工作原理：1、HRM型原料立式磨重要结构见下图：1、选粉装置2、中壳体3、磨辊装置4、传动臂5、限位装置6、下壳体7、传动装置8、液压系统9、副油缸2、工作原理如下：电动机通过减速机带动磨盘转动。物料从进料口落在磨盘中央，同时热风从进风口进入磨内，在离心力的作用下，物料向磨盘边沿移动，通过磨盘上的环形槽时受到磨辊的碾压而粉碎，粉碎后的物料在磨盘边沿被风环处高速气流带起，大颗粒直接落到磨盘上重新粉磨，气流中的物料通过度离器时，在旋转转子的作用下，粗粉落到磨盘重新粉磨，合格细粉随气流一起出磨，在收尘装置中收集，即为产品。具有水分的物料在与热气体的接触过程中被烘干，达成所规定的产品水分。3、特 点（1） 物料重要是依靠磨辊的重量和加压装置的压力被破碎和粉磨的，在粉磨过程中物料始终受到磨辊的压力作用，而磨辊和磨盘间不是纯滚动，物料受到的是多向应力的作用，因此提高了磨机的粉磨能力和粉磨效率。（2） 由于物料进入磨机后就与热气体充足接触，被粉磨后又悬浮在热气中，能充足地进行热将互换。在粉磨的同时也烘干了物料。（3） 磨辊的碾磨压力由液压系统提供，通过加压装置、传动装置传给磨辊而施加 在物料上，通过调节液压系统的压力，来改变粉磨压力的大小以满足粉磨不同硬度物料的规定。（4） 为了避免磨机工作时因断料磨辊与磨盘的直接接触而导致的剧烈震动，磨辊和磨盘之间应有一定的间隙，因此，特别设计了控制间隙大小的限位装置，并通过限位装置可随时了解磨辊下物料的厚度，因此保证了磨机在安全和经济的工作条件下运营。（5） 辊套和磨盘衬板采用了高硬度合金耐磨材料，磨损小，寿命长，并且当辊套磨损到一定限度时，还可翻面使用，从而延长辊套的使用寿命。（6） 磨辊能借助于辅助油缸的作用，将其翻出机外，更换检修非常方便。（7） 磨盘周边上设有防止盘座磨损、调节风环处风速和盘上物料厚度的装置，可保证立式磨的生产能力及其经济运营。（8） 分离器由变频器电机、减速机构、转子、壳体等部分组成。电机通过减速机构带动分离器转子转动，通过调整电机转速而获得不同细度的产品。（9） 主减速机由稀油站供油产生循环润滑系统，以保证主减速机的正常运营。四、

Operating principle1. The primary structure of HRM raw material vertical roller mill can be seen in the following drawing:1. Separating device; 2. Middle shell; 3. Grinding roller device; 4. Driving arm; 5. Limit device; 6. Lower shell; 7. Driving device; 8. Hydraulic system; 9. Auxiliary oil cylinder 2The operating principle is as follows: The motor drives the grinding disc to rotate by the reducer. The material falls into the center of the grinding disc from the inlet orifice, meanwhile the hot blast enters into the mill from the inlet opening, under the effects of the centrifugal force the material moves to the edge of the grinding disc, and then it is ground and pressed by the grinding roller while passing through the annular groove on the grinding disc, the crushed material is brought up by the high speed air jet in the vane at the edge of the grinding disc, the large granule directly falls into the grinding disc to be newly ground, while the material in the airflow passing through the separator and under the effects of the rotary rotor, the rough powder falls into the grinding disc to be newly ground, the eligible fine powder follows the airflow together coming out the mill, the products are collected by the dust collector. The material with the moisture which contacts with the hot gas is dried and reaches the permissible moisture of the products.3. Features (1) The material is crushed and ground which is mainly depended on the weight of the grinding roller and the pressure of the pressure device. During the grinding process, the material is always under the effects of the pressure of the grinding roller, while between the grinding roller and the grinding disc is not the purely rolling, the material is under the multi-axial stress effects, so the grinding capacity and the grinding power of the mill are improved. (2) The materials get full contact with hot air after entering the mill, then they become powder and suspend in the hot air after been ground, as a result, they make full exchange with hot gas and so the materials are dried while being ground. (3) The grinding pressure of the grinding roller is provided by the hydraulic system, the pressure is brought to bear the material through the pressure device and the driving device to pass into the grinding roller, the magnitude of the grinding pressure is transferred through adjusting the pressure of the hydraulic system to satisfy the requirements of grinding the materials with different hardness.(4) For avoiding the strenuous vibration which is created by the grinding roller contacting with the grinding disc directly during stopping feeding, there should be a certain clearance between the grinding roller and the grinding disc, therefore, so the limit device is specially designed for controlling the size of the clearance, and through the limit device the depth of the material under the grinding roller can be realized at any moment, so the mill can be guaranteed in the safe and economical working conditions to operate. (5) The roller sleeve and the lining board of the grinding disc ad
