回转滚筒干燥机
一、工作原理及应用范围介绍 Introduction of Working Principle and Scope of Application
需干燥的物料经加料器输送到回转圆筒干燥机的进料端。物料从较高一端加入，热载体可由低端进入与物料呈逆流热交换形式；也可以设计为热载体与物料并流进入筒体内。干燥筒体转动，物料在重力作用下运行到较低的一端，湿物料在圆筒内向前移动过程中，与热空气进行传热传质，从而达到干燥之目的，被干燥的物料从出料端送出。在圆筒内装有各种形式的抄板（抄板形式、结构是依物料特性的不同而不同）其作用是把物料抄起来洒下，形成料幕，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。尾气经旋风分离器将气体内所带物料捕集下来。如需进一步减少尾气含尘量，可设置袋式除尘器或水浴除尘器除尘后排放。
回转圆筒干燥机是一种连续处理大批量物料的干燥设备，广泛应用在各种散粒物料的干燥，现已发展到应用于溶液及膏状物料的干燥上。运转可靠，操作弹性大，适应性强，处理能力大，物料的适应性强，现广泛应用于各行业，如：
1. 化工、矿工、冶金等行业：矿石、矿渣、煤、金属粉末、粘土、硅藻土、高岭土。
2. 农业、饲料、肥料行业：秸秆、牧草、树叶、鱼粉、玉米酱、淀粉渣、酒糟、药渣、果渣、酱油渣、甘蔗渣、草炭、有机复合肥、污泥、水产品废料、食品厂废料、屠宰厂废料、有机肥料、无机肥料、磷肥硫铵。
3. 对有特殊要求的粉状、颗粒状物料干燥。
4. 如各种结晶体、轻质碳酸钙、活性白土、磁粉、石墨、无机泥浆、陶土、石灰浆、矿石泥浆、磷矿渣、铝厂赤泥。
5. 要求低温干燥，且需要大批量连续干燥的物料。
The materials to be dried shall be conveyed to the charge end of rotary drum drier via the feeder. The materials shall be charged from the relatively high end, and the heat carrier can enter from the relatively low end to present a counter-current heat exchange form together with the materials; it also can be designed as heat carrier and materials entering into the drum in cocurrent flow. The drier drum rotates, the materials move to the relatively low end under the action of gravity, the wet materials conduct heat and mass transfer with heat air in the process of moving forward in the drum, thus to reach the purpose of drying, and the materials that have been dried will be delivered from the discharge end. The drum is installed with various types of shovelling plates (according to different characteristics of materials, types and structures of shovelling plates are different), which shovels and sprays the materials to form a materials curtain to increase the contact surface between the materials and the airflow to improve the drying rate and promote the materials moving ahead. The end gas catches the materials carried by air via a cyclone separator. If it is necessary to further reduce the dust content of end gas, a bag filter can be set up or dust shall discharged after dust is removed with a wet dust collector.
Rotary drum drier is a kind of drying unit for continuous processing of materials in large batches, which is widely used for drying for various granular materials. Now it has been developed for drying of solution and paste materials. With reliable operation, large operation flexibility, strong adaptability, large processing ability, and strong adaptability to various materials, now it is widely used in various industries, for example:
1. Chemical, miner and metallurgical industries: ore, slag, coal, metal powder, clay, kieselguhr and kaolin.
2. Agricultural, feed, fertilizer industries: straw, pasture, leaves, fish meal, corn sauce, starch residue, vinasse, herb residue, lees, medical, pomace, soy sauce residue, bagasse, peat, organic compound fertilizer, sludge, waste of aquatic products, waste of food factory, waste of the abattoir, organic fertilizer, inorganic fertilizer, phosphate fertilizer ammonium sulphate.
3. Drying of powdery and granular materials with special requirements.
4. Various crystalline solids, light calcium carbonate, activated clay, magnetic powder, graphite, inorganic mud, argil, lime slurry, ore slurry, phosphor slag and aluminum plant red mud.
5. Materials requiring low temperature drying and continuous drying in large batch.
二、特点Characteristics
1.干燥机处理能力大，燃料消耗少，干燥成本低，系连续不间断的大批量的烘干装置。
2.结构简单，操作方便 , 清扫容易。
3.故障少，设备维护费用低。
4.适应范围广，可以用于处理颗粒状物料与各种流动性相对比较好一点的物料的脱水烘干。
5.操作弹性大,可扩展能力强，产能适应性强，即使产量小幅度增加，也无需更换设备。
1. With large processing capacity, less fuel consumption and low drying cost, the drier is a drying unit for continuously drying in large batch.
2. It is of simple structure, convenient for operation and easy to clean.
3. It has less troubles and low equipment maintenance costs.
4. It has wide scope of application , and it can be used for dehydration and drying of granular materials and various materials with relatively good liquidity.
5. With large operation flexibility, strong expandable ability and strong capacity adaptability, it is not necessary to replace the drying unit even if the output increases slightly.
