高效轉(zhuǎn)筒烘干機(jī)是一種處理量大的干燥設(shè)備，它廣泛用于冶金、建材、化工等行業(yè)。影響烘干效果是整個(gè)烘干配套系統(tǒng)的綜合平衡問(wèn)題，烘干機(jī)優(yōu)質(zhì)高產(chǎn)的根本條件是要做到“風(fēng)”、“火”、“料”的平衡。
高效轉(zhuǎn)筒烘干機(jī)進(jìn)料及出料密封圈采用剛性迷宮式，改進(jìn)了橡膠板密封使用時(shí)間短，易燒壞，易進(jìn)冷風(fēng)的缺陷。高效烘干機(jī)增加定量進(jìn)料裝置，保證了烘干機(jī)參數(shù)的相對(duì)穩(wěn)定。根據(jù)物料特性及物料出窯的粒度需要，高效烘干機(jī)加鏈條或短鋼管，起傳熱、粉碎、阻氣流的作用。高效烘干機(jī)轉(zhuǎn)筒內(nèi)增加了板面鏈條和懸掛鏈條，不僅增強(qiáng)其熱傳遞性而且有效地防止揚(yáng)板粘結(jié)，增強(qiáng)對(duì)物料的破碎功能，使較大球團(tuán)難以形成。高效烘干機(jī)必須選擇處理風(fēng)量大的除塵器，保證烘干機(jī)進(jìn)料端有一定的負(fù)壓，及時(shí)將燃燒爐產(chǎn)生的高溫氣體吸入烘干機(jī)，使之與烘干物料迅速發(fā)生熱交換，及時(shí)排出，盡可能降低機(jī)體內(nèi)廢氣濃度，達(dá)到快速烘干的目的。
熱風(fēng)爐是烘干供熱的關(guān)鍵設(shè)備, 決定了物料的烘干產(chǎn)量和質(zhì)量。目前物料烘干應(yīng)用的熱風(fēng)爐主要有三大類(lèi)：燃?xì)鉄犸L(fēng)爐、燃油熱風(fēng)爐和燃煤熱風(fēng)爐。但依我國(guó)國(guó)情，絕大多數(shù)的地區(qū)和企業(yè)沒(méi)有燃?xì)鈼l件，而燃油的成本太昂貴。所以國(guó)內(nèi)企業(yè)多是選用燃煤熱風(fēng)爐。熱風(fēng)爐供熱量大小是否配套至關(guān)重要，即便保證了物料在烘干機(jī)內(nèi)的停留時(shí)間，加料也均勻，通風(fēng)除塵設(shè)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.
