8、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,物料向磨盘边缘移动,经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缘被风环处高速气流带起,大颗粒直接落到磨盘上重新粉磨,气流中的物料经过分离器时,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。含有水分的物料在与热气体的接触过程中被烘干,达到所要求的产品水分。3、特 点(1) 物料主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
9、入磨机后就与热气体充分接触,被粉磨后又悬浮在热气中,能充分地进行热将交换。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要求。(4) 为了避免磨机工作时因断料磨辊与磨盘的直接接触而造成的剧烈震动,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行。(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,而且当辊套磨损到一定程度时,还可翻面使用,从而延长
10、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,可确保立式磨的生产能力及其经济运行。(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行。四、 工艺流程:hrm型原料立式磨在粉磨系统中的运用主要有以下几种形式,详见工艺流程图一、图二。工艺流程图一1.电子皮带秤2.胶带输送机3.电磁除铁器4.回转锁风喂料机5.hrm型立式磨6.外循环提升7
