转筒烘干机可用于烘干锯末、煤泥、石膏、粘土、复合肥、煤泥、污泥、金属非金属矿等块状、泥状、颗粒状物料,目前已在冶金、化工、水泥、选矿等行业得到了广泛的应用。 在转筒烘干机中,物料的干燥主要在于干燥过程中例如:温度、风速、干燥的时间、及其物料烘干时是否均匀等因素。物料在转筒烘干机中干燥时,如果风的温度过低,则会造成干燥时间过长;如果风的温度过高,则会造成干燥时间过短,但是,风的温度过高会造成物料的生化反应,比如会造成物料的成分发生变化。如果物料在干燥时转筒烘干机内风速太小,则会延长烘干时间,而且物料有收缩的危险,影响烘干后的品质,如果风的速度过大,也会使物料烘干的速度过快,但因风速过快而导致烘干较快的话,物料会有干裂的危险。如果在烘干时,物料烘干不均匀,会导致一些物料温度过高,含水量过低;如果部分物料温度过低,则会造成水分含量较高,是物料的烘干未能达到用户的要求,对于专一烘干某种物料时,转筒烘干机内风温和速度是很容易确定的。 如果物料不够单一,则转筒烘干机干燥的均匀性是很难控制的,如果不同物料的干湿度相差很大,会严重影响转筒烘干机烘干后物料的质量。这时就需要物料通风层内气流分布极度均匀了。如果转筒烘干机内气流分布不够均匀,某些部位风度过大,某些部位风速过小,通过传热传质会造成一部分温度过高,水分过低,一部分温度过低,水分过高等结果。郑州正科转筒烘干机结构合理、制作精良、产量高、能耗少,该机选用合理的运行参数,煤耗量和电耗量比一般

When the drum dryer drying causes of dry material Drum dryer can be used for drying sawdust, coal, gypsum, clay, compound fertilizer, coal slurry, sludge, metal, nonmetal ore block, slimy, granular materials, has been in metallurgy, chemical industry, cement, mineral processing and other industries widely used. In the drum dryer, material drying mainly lies in the drying process such as temperature, wind speed, the drying time, and its drying if uniform and other factors. Material in the drum dryer dry, if the temperature is too low, the wind will cause the drying time is too long; If wind temperature is too high, it will cause the drying time is too short, but the wind of the high temperature will cause the material of biochemical reactions, such as material composition change. If material in dry drum dryer wind speed is too small, will extend the drying time, and the material is in danger of contraction, influence the quality after drying, if the wind speed is too large, also can make
