高效轉筒烘干機是一種處理量大的干燥設備，它廣泛用于冶金、建材、化工等行業。影響烘干效果是整個烘干配套系統的綜合平衡問題，烘干機優質高產的根本條件是要做到“風”、“火”、“料”的平衡。
高效轉筒烘干機進料及出料密封圈采用剛性迷宮式，改進了橡膠板密封使用時間短，易燒壞，易進冷風的缺陷。高效烘干機增加定量進料裝置，保證了烘干機參數的相對穩定。根據物料特性及物料出窯的粒度需要，高效烘干機加鏈條或短鋼管，起傳熱、粉碎、阻氣流的作用。高效烘干機轉筒內增加了板面鏈條和懸掛鏈條，不僅增強其熱傳遞性而且有效地防止揚板粘結，增強對物料的破碎功能，使較大球團難以形成。高效烘干機必須選擇處理風量大的除塵器，保證烘干機進料端有一定的負壓，及時將燃燒爐產生的高溫氣體吸入烘干機，使之與烘干物料迅速發生熱交換，及時排出，盡可能降低機體內廢氣濃度，達到快速烘干的目的。
熱風爐是烘干供熱的關鍵設備, 決定了物料的烘干產量和質量。目前物料烘干應用的熱風爐主要有三大類：燃氣熱風爐、燃油熱風爐和燃煤熱風爐。但依我國國情，絕大多數的地區和企業沒有燃氣條件，而燃油的成本太昂貴。所以國內企業多是選用燃煤熱風爐。熱風爐供熱量大小是否配套至關重要，即便保證了物料在烘干機內的停留時間，加料也均勻，通風除塵設備合理。

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.
