摘要 
本文在分析单筒式回转烘干机存在问题的基础上，介绍了套筒式回转烘干机的结构特点和工作原理，并依据该机在水泥厂的使用效果、实测数据和计算结论，说明该机无论在理论还是实践中都是一种高效、节能的理想烘干设备。套筒式烘干机是通过对单筒烘干机的单一筒体改为叠在一起的两筒或三筒，以缩短烘干机的外形尺寸。该机工作时，物料和热气流依次进入内外筒体，在烘干机内作“V”或“N”形往复折流后，充分利用热能烘干物料后再卸出。该烘干机筒体部分由两个筒轴水平放置的内外套筒组成，内通为一锥筒，外筒为直筒，这就使通体的截面得到充分利用，其筒体外形总长度约为相当的单筒的50％－60％，从而大幅度的减少了占地面积和厂房建筑面积。套筒式烘干机将以其结构紧凑、占地面积小、热效率高、投资省、适应性强、运转可靠等特点，为水泥厂的原、燃料烘干提供了一种较理想的烘干设备。

Abstract
The single cylinder type of this text at analyze dryer turns round the foundation exsits the problem is last, introducing a cylinder type turns round the construction characteristics of the dryer with work principle, and according to that machine usage in cement works result, solid measure the data with compute the conclusion, explain that machine to is all a kind of in theories still practice regardless efficiently, the ideal of the economy energy dries the equipments.A cylinder type dryer is an one to pass to the single the dryer of cylinder to change for together of two cylinder or three cylinder , to shorten the shape size of the dryer.When that machine work, the material flows to enter the of cylinder outside the inside one by one in order with the hot air, after dryer inside make" V" or" N" form back and forths fold flow, make use of well the thermal energy dries the material empress unloads again.The dryer's cylinder part inside coat cylinder that place be constituted by two cylinder stalk level, inside is a cylinder , the outside cylinder is for keeping the cylinder , this make the an of the of cylinder got to make use of well, its cylinder shape total length invites 50% － 60% of the very single cylinder , from but significant decrease cover the area to construct the area with the factory premises [资料来源：www.THINK58.com]

0.1 概述 
单筒式回转烘干机适用范围广、操作方便、运转率高，在水泥工业中被广泛用于烘干粘土、矿渣、碎石、煤等原、燃料。干燥时，热空气或热烟气将热量传给物料，使水份蒸发，同时依靠通风设备的作用，使干燥设备内的干燥介质不断更新，以排除水汽。干燥设 [资料来源：http://think58.com]
