转筒烘干机在多行业、多领域的干燥工作中发挥着巨大的作用。依据物料的不同又可专业化分为煤泥烘干机、河沙烘干机、矿粉烘干机等等多种粉状类物料烘干器械。其原理和和结构大同小异，都属于转筒旋转式干燥。  由于物料的形态数以粉状的，其形态比价松散。所以转筒烘干机是***适合的干燥设备。通过燃烧室带来的热量，筒体的进行旋转，物料在内部来回运动充分受热，水分得到蒸发。在这其中扬料板发挥着决定性的作用。  何为扬料板？就是在干燥过程中对物料不断的扬起，因此物料变得均匀、分散。受热面积扩大，干燥效率提升。对于某些粘性较大的物料还配有打散装置。  扬料板的形式也是多种多样的。其功能各有优势。例如圆弧形、十字架型、升举式等等。下面我们以两幅图为代表看看转筒式烘干机的扬料板与工作原理。
Drum dryer dry work in the field of industry, plays a huge role. According to the material of different can be divided into professional again coal slime dryer, river sand dryer, kuangfen dryer and so on many kinds of powdery materials drying equipment. The principle and structure and the same, all belong to drum rotary drier. Because of the material form of powder, its shape comparison. So the drum dryer is the most suitable drying equipment. Through the combustion chamber of the heat, the cylinder rotate, material movement back and forth in internal heat fully, moisture evaporation. In the feed plate plays a decisive role. What is a feed plate? Is a constantly raise the material in the drying process, so the material evenly, scattered. Heating area expanded, drying efficiency. For some larger viscous material with break up device. Is also varied in the form of feed plate. The functions of each have an advantage. Such as the circular arc form, cross, lifting type and so on
