適用于化工、礦山、冶金等行業(yè)大顆粒、比重大物料干燥。 如:礦石、高爐礦渣、煤、金屬粉末、磷肥、硫銨。HZG 系列直接加熱式回轉(zhuǎn)滾筒干燥機(jī)
◆ 對有特殊要求的粉狀,顆粒狀物料的干燥。如:HP發(fā)泡劑、酒 糟渣、輕質(zhì)碳酸鈣、活性白土、磁粉、石墨、藥渣。
◆ 要求低溫干燥,且需大批量連續(xù)干燥的物料。HZG 系列直接加熱式回轉(zhuǎn)滾筒干燥機(jī)
◆ Applicable for drying big particles,heavy particls in the f ield of chemical mining and metallurgical industry. For example:slag of blast furnace,coal,metallic powder,phosphorus fertilizer,thiamin and so on.
◆ For drying powder,grannle raw materials which have special require- ments such as:HP vesicant,lees,precipitated calcium carbonate,actived clay,magnetic powder,graphite,and residue medical and so on.
◆ For materials to be dried under low temperature and large production in line.
◆ 主要用于硬磁鐵氧體粉料的預(yù)燒,亦可應(yīng)用于水泥、冶金、化工等行 業(yè)。設(shè)備由主窯及其支承傳動裝置、冷卻管、燃油系統(tǒng)、電氣控制、二 次進(jìn)風(fēng)裝置、排氣除塵裝置和預(yù)熱窯體等組成。具有超溫報警、過載報 警、工作溫度自動控制、窯內(nèi)氧氣可調(diào)等功能。
◆ The machine is mainly used in per buring of rigid magnet oxygen pulverized pow- der ,it is also suitable for the cement ,metallurgy and chemical industry ,it is con- sisted of main kiln body,supporting drive set.cooling pipe. oil fuel system,electricity control,secondary air inlet set,exhaust dust set and warm-up kiln body etc.Main fanction of this dryer includes :over temperature,over loading,auto control for working temperature,oxygen atmosphere is adjustable in the kiln etc.
◆ 濕物料從干燥機(jī)一端投入后,在內(nèi)筒均布的抄板器翻動下,物料在干燥 器內(nèi)均勻分布與分散,并與并流(逆流)的熱空氣充分接觸,加快了干燥傳 熱、傳質(zhì)推動力。在干燥過程中,物料在帶有傾斜度的抄板和熱氣流的作 用下,可調(diào)控地運動至干燥機(jī)另一段星形卸料閥排出成品。
◆ Wet material is loaded from one head of the drier, and then it is stirred by the bafflers that is uniformly distributed in the barrel.Material is uniformly distributed and dispersed in the drier,fully contact the hot air in paraller (or counter)flow,so the drying process is expedited
,and the impulsion power of media transfer is enhanced,During the drying process ,material is under the effect of angled baffler and hot air and moves to the rotary valve that is at the other head of the drier.
◆ 轉(zhuǎn)筒干燥器機(jī)械化程度高,生產(chǎn)能力較大。
◆ 流體通過筒體阻力小,功能消耗低。
◆ 對物料特性的適應(yīng)性比較強(qiáng)。
◆ 操作穩(wěn)定,操作費用較低,產(chǎn)品干燥的均勻性好。
◆ The mechanial level content of rotating drier is high and its productive capacity is large.
◆ Because the resistance when fluid passes through the cylinder is small,the consumption of power is low.
◆ Have strong adoptability to raw materials.
◆ Its operation is stability and the cost of operation is cheap.The homogeneity of dried product is good.
