高效转筒烘干机是一种处理量大的干燥设备,它广泛用于冶金、建材、化工等行业。影响烘干效果是整个烘干配套系统的综合平衡问题,烘干机优质高产的根本条件是要做到“风”、“火”、“料”的平衡。
高效转筒烘干机进料及出料密封圈采用刚性迷宫式,改进了橡胶板密封使用时间短,易烧坏,易进冷风的缺陷。高效烘干机增加定量进料装置,保证了烘干机参数的相对稳定。根据物料特性及物料出窑的粒度需要,高效烘干机加链条或短钢管,起传热、粉碎、阻气流的作用。高效烘干机转筒内增加了板面链条和悬挂链条,不仅增强其热传递性而且有效地防止扬板粘结,增强对物料的破碎功能,使较大球团难以形成。高效烘干机必须选择处理风量大的除尘器,保证烘干机进料端有一定的负压,及时将燃烧炉产生的高温气体吸入烘干机,使之与烘干物料迅速发生热交换,及时排出,尽可能降低机体内废气浓度,达到快速烘干的目的。
热风炉是烘干供热的关键设备, 决定了物料的烘干产量和质量。目前物料烘干应用的热风炉主要有三大类:燃气热风炉、燃油热风炉和燃煤热风炉。但依我国国情,绝大多数的地区和企业没有燃气条件,而燃油的成本太昂贵。所以国内企业多是选用燃煤热风炉。热风炉供热量大小是否配套至关重要,即便保证了物料在烘干机内的停留时间,加料也均匀,通风除尘设备合理。

High efficiency rotary drum dryer is a kind of processing large amount of drying equipment, it is widely used in metallurgy, building materials, chemical industry. Effects of drying effect of the drying system is the comprehensive balance, drying machine with high yield and good quality is the basic condition to achieve the " wind"," fire"," material " in the balance.
High efficiency rotating cylinder drying machine feeding and discharging sealing ring adopts the rigid labyrinth, improved rubber sealing plate using time is short, easy to burn, easily into the cold air defects. High efficiency dryer increases quantitative feeding device, guarantees the drying machine parameters were relatively stable. According to the characteristics of the material and the material out of the kiln size needs, efficient dryer chain or short pipe, heat transfer, crushing, resistance flow plays a role. High efficiency dryer drum increases the surface chains and a hanging chain, not only enhanced the heat transfer and effectively prevent the spread plate bonding, enhancement of the crushing function, so that a larger pelletizing to form. High efficiency dryer must select the volume of dust collector, ensuring the drying machine feeding end of certain negative pressure, timely combustion furnace to produce high temperature gas suction dryer, and make the material drying heat exchange occurs rapidly, timely discharge, as far as possible to reduce the concentration of the waste, achieve rapid drying purpose.
The hot-blast stove is the key equipment of drying and heating, determines the material drying yield and quality. The application of hot blast stove for drying materials are mainly three categories: gas furnace, hot stove fuel and coal burning hot air furnace. But according to the national conditions of our country, the vast majority of regions and enterprises without gas conditions, and the fuel cost is too expensive. So the domestic enterprises is a selection of coal fired hot blast stove. Hot blast stove heating quantity matching is very important, even if the material is guaranteed in the dryer and the residence time, feeding is uniform, ventilation dust removal equipment.
