叙述矿石烘干机的应用范围及工作原理
矿石烘干机广泛用于建材、冶金、选矿、化工、水泥等行业，可用于烘干矿石、电石渣、石灰石、粘土、河沙、石英砂、水渣等物料 吊钩式抛丸机
矿石烘干机或矿石干燥机也是一种回转式烘干机，主要由回转筒体、引风设备、高速打散设备、扬料板、自清扫装置、传动装置、输送设备、热风设备、减速机、支撑装置及密封装置等部件组成
矿石烘干机设计合理，制作精良，性能稳定，工艺，产量高，能耗低，占地面积?

工作原理：矿石由皮带输送机或斗式提升机送到料斗，然后经料斗的加料机通过加料管道进入加料端
加料管道的斜度要大于物料的自然倾角，以便物料顺利流入烘干机内
烘干机圆筒是一个与水平线略成倾斜的旋转圆筒
物料从较高一端加入，载热体由低端进入，与物料成逆流接触，也有载热体和物料一起并流进入筒体的
随着圆筒的转动物料受重力作用运行到较底的一端
湿物料在筒体内向前移动过程中，直接或间接得到了载热体的给，使湿物料得以干燥，然后在出料端经皮带机或螺旋输送机送出
矿石烘干机筒体内壁上装有抄板，作用是把物料抄起来又撒下，使物料与气流的接触表面增大，以提高干燥速率并促进物料前进
载热体经干燥器以后，一般需要旋风除尘器将气体内所带物料捕集下来(载热体一般分为热空气、烟道气等)
如需进一步减少尾气含尘量，还应经过袋式除尘器或湿法除尘器后再放排放
