桨叶干燥机是一种间接传导加热式干燥设备,适用于处理糊状、粉状、颗粒状等热稳定性较好的物料。经过特殊配置,可用于处理热敏性物料、干燥过程中需要回收溶剂的物料、需要粗真空干燥的物料。同时,桨叶干燥机还可用于粉状、粒状物料的冷却和一些特殊物料的喷射冷却介质的冷却结晶。也可注入加热介质,加热待加热物料和反应器。工作原理:在桨式干燥机的夹套壳体内,有两个平行的轴,轴上有交错的桨叶。每个轴有几个空心扇形桨叶,它们以一定的间距交错在一起。有进剪面和回剪面两种桨叶,轴低速旋转。加热介质通过万向旋转接头进入空心旋转轴和桨片。经传热干燥后,通过旋转接头排出。物料被连续地送入设备,然后在桨附近搅拌混合。 At the same time, the material is gradually dried by the heat conduction of paddle and jacket. The height of overflow weir can be changed to adjust residence time. Applicable Materials: Widely used in chemical, mining, metallurgical and other industries, such as ore, gypsum, coal, metal powder, diatomaceous earth, kaolin, and various of sludge drying.
