美國FEECO回轉(zhuǎn)烘干機(回轉(zhuǎn)窯，旋轉(zhuǎn)窯，旋轉(zhuǎn)干燥器)介紹-金陵干燥

譯文：回轉(zhuǎn)烘干機是什么？

有時被稱為旋轉(zhuǎn)窯，旋轉(zhuǎn)干燥器，是一種類型的工業(yè)干燥機，以減小或^小化它正在處理的材料直接接觸，通過把它與加熱氣體的水分含量。烘干機是由一個大型的，旋轉(zhuǎn)的圓筒形管，通常混凝土柱或梁鋼的支持。機稍微傾斜，使得排出端是低于材料的進料端，以傳達材料在重力作用下通過干燥器。以進行干燥的材料進入干燥器的較高端，和干燥器轉(zhuǎn)動時，該材料被抬起由一系列的內(nèi)部散熱片，干燥機的內(nèi)壁襯。當材料變得足夠高，以關(guān)閉翅片回滾，它回退到下降到干燥器的底部，通過熱空氣流，因為它屬于。該空氣流可以被朝著從進料端（被稱為順流旋轉(zhuǎn)干燥器），或朝向的進料端從排出端（稱為作為逆流旋轉(zhuǎn)干燥器）的排出端。的空氣流可以由空氣和爐排出的廢氣（稱為作為一個直接加熱的烘干機）或簡單的熱空氣（稱為作為間接加熱干燥器，一般進行造成產(chǎn)品污染的風險較小）的混合物。

旋轉(zhuǎn)干燥器也是能夠煅燒的材料，或?qū)煞N或多種材料混合，有時刺激兩種或更多種材料之間的反應(yīng)。水泥行業(yè)的回轉(zhuǎn)窯（因為它被調(diào)用時，它不被用于干燥的材料）是常用的，導(dǎo)致它的兩個主要組成部分之間的一個關(guān)鍵反應(yīng)。

什么樣的材料適合用旋轉(zhuǎn)式干燥機？

典型的材料旋轉(zhuǎn)干燥器過程包括：聚集，農(nóng)業(yè)谷物和副產(chǎn)品，動物飼料，動物糞便，污泥，陶瓷，粘土，化肥，石膏，鐵精礦，石灰石，金屬屑，開采礦石及精礦，市政污泥，城市廢物，有機和無機化學(xué)品，造紙污泥，塑料粒，鉀肥，再生粉塵，橡膠顆粒，銷售，砂鋼廠廢物/污泥，糖尿素顆粒和晶體。

順流回轉(zhuǎn)式烘干機VS逆流轉(zhuǎn)筒干燥器

在順流旋轉(zhuǎn)干燥器，加熱的干燥空氣在相同的方向上流動的產(chǎn)品，并在計數(shù)器的當前旋轉(zhuǎn)模型干燥氣流行進反對的流動的產(chǎn)品。這些旋轉(zhuǎn)干燥器直接將產(chǎn)品暴露在由熱源產(chǎn)生的熱空氣。當鼓轉(zhuǎn)動時，解除安裝在鼓外殼的內(nèi)部翻滾，滑動的“飛行”，解除和淋浴材料到空氣流中。起重航班仔細設(shè)計，以適應(yīng)在干燥的材料，確保產(chǎn)品均勻地暴露。這種攪拌^終導(dǎo)致更高的效率，并減少了處理時間相比，固定單元。服用1小時的處理，在一個固定的爐，在旋轉(zhuǎn)干燥器中采取短短幾分鐘內(nèi)的情況并不少見。許多類型的干燥燃料和控制方法的選項，包括獨立的的微處理器控制器或PLC控制器，直接與工廠控制系統(tǒng)。

組合回轉(zhuǎn)烘干機/冷卻器

這種高度靈活的新產(chǎn)品FEECO結(jié)合在一個單一的安裝利用注入空氣，以產(chǎn)生流化行動的材料的干燥和冷卻功能。可以使用附加的內(nèi)部間接冷卻，以幫助減少的粉塵收集和排氣系統(tǒng)的負擔。這種成熟的設(shè)計可以幫助解決遇到的問題在安裝干燥/冷卻系統(tǒng)在現(xiàn)有的空間或建筑物。冷卻罩部分可以改裝到FEECO和競爭品牌的旋轉(zhuǎn)干燥器。

原文：What is a Rotary Dryer?

The rotary dryer, sometimes known as a rotary kiln, is a type of industrial dryer employed to reduce or minimize the moisture content of the material it is handling by bringing it into direct contact with heated gas. The dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. The dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under gravity. Material to be dried enters the higher end of the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot air stream as it falls. This air stream can either be moving toward the discharge end from the feed end (known as a co-current rotary dryer), or toward the feed end from the discharge end (known as a counter-current rotary dryer). The air stream can be made up of a mixture of air and furnace exhaust fumes (known as a direct heated dryer) or simply hot air (known as an indirect-heated dryer, which generally carries a lesser risk of causing product contamination).

The rotary dryer is also capable of calcining the material, or mixing two or more materials, and sometimes stimulating a reaction between two or more materials. The rotary kiln (as it is called when it is not being used to dry a material) is commonly used in the cement industry to cause a key reaction between two of its major components.

What kind of materials do Rotary Dryers process?

Typical material rotary dryers process include: aggregates, agricultural grains and by-products, animal feeds, animal waste, biosolids, ceramics, clay, fertilizers, gypsum, iron ore concentrates, limestone, metal chips and shavings, mining ores and concentrates, municipal sludge, municipal waste, organic and inorganic chemicals, paper sludge, plastic pellets, potash, reclaimed dust, rubber pellets, sales, sand steel mill waste / sludges, sugar urea prills and crystals.

Co-current Rotary Dryers vs Counter Current Rotary Dryers

In co-current rotary dryers, the heated drying air flows in the same direction as the product, and in counter current rotary models the drying airflow travels against the flow of the product. These rotary dryers directly expose the product to hot air produced by the heat source. As the drum rotates, lifting “flights” mounted on the inside of the drum shell tumble, slide, lift and shower the material into the air stream. Lifting flights are carefully designed to accommodate the material being dried and ensure the product is uniformly exposed. This agitation ultimately leads to higher efficiencies and reduces processing times compared to stationary units. It is not uncommon for a process taking 1 hour in a stationary furnace to take just a few minutes in a rotary dryer. A number of options for types of drying fuel and control methods are available including stand-alone microprocessor controllers or PLC controllers that directly interface with plant control systems.

Combination Rotary Dryer / Cooler

This highly versatile new product from FEECO combines drying and cooling functions in a single installation utilizing injected air to produce a fluidizing action on the material. Additional internal indirect cooling can be used to help reduce the burden to the dust collection and exhaust system. This proven design can help solve problems encountered in installing a drying/cooling system in an existing space or building. The cooling hood section can be retrofitted to FEECO and competing brands of rotary dryers.
