The dryer is designed for compound fertilzer production process and suitable for each system of compound fertilizer production line such as preliminary drying handling ordinary peroxy calcium phosphate and drying granualted material.在作为造粒肥料干燥机使用时,烟道气和物料的流向应采用顺流方式,烟道气进气温度要根据各体系的操作条件决定,一般低于400℃While using as dryer for granulated fertilizer, flow direction of flue pipe gas and material shall adopt downstream manner; inlet gas temperature of flue pipe gas can be decided according to operation conditions of each system; In general, it shall be less than 400℃. 选用合适生产能力的干燥机,可达到国标所规定的各种浓度复混肥料最终水份含量。

Adopt suitable capacity dryer to achieve stipulated final water content of each density compound fertilizer as per national standard. 二、主要技术规范Main technical requirements我公司生产的各种规格的干燥机主要技术参数如表1Main technical parameters of all kinds of dryer manufactured by our company, as follows(table 1):干燥机技术性能表Table of technical parameters for dryer产品规格(m)Specification生产能力t/hProductive capacity 筒 体转 速r/minRotatiNgspeed ofshell筒体斜度(度)Inclination of shell进气温度℃Inlet air temperature电机Model减速机Reducer设备总重(㎏)Total weight of equipment型 号Model功率(kw)Power型 号Model速比Speed ratioφ3.0×26m25～354.003.5％＜3501LG0283-4AA70110H3SH1045115φ3.0×30m25～403.853.5％＜3501LG0283-4AA70110H3SH1045130φ3.2×30m35～503.852.0＜3501LA4310-4AA70160H2SH0935.5155φ3.6×32m50～902.22.0＜3501LG4310-4AA60200H3SH1535.5175φ3.7×31m50～902.21.26＜3501LG4310-4AA60200H3SH1571195φ4.3×33.5200～2503.41.83＜3501LA4352-4AA60470H3SH1745256注:干燥机生产能力与进干燥机的物料、初水分、出料水分、进风温度和工矿条件及工艺有关,表内数据谨供参考。

All data in the table is only for reference.三、干燥机生产能力(吨/小时) Productive capacity of dryer(t/h)干燥机生产能力一般由公式 G= AV 大略算出 W1 W2 1000(100-W2)Generally calculating productive capacity of dryer as per the formula:G= AV W1 W2 1000(100-W2)式中in the formula: G 干物料每小时产量output of dry material per hour(t/h) V 干燥机筒体容积volume of dryer shell(m³见表1 seeing table 1) W1 入干燥机物料含水量water content of material fed into dryer(％) W2 出干燥机物料含水量water content of material discharged from dryer(％) A 干燥的水份蒸发强度 water evaporation strength of dryer A值与被干燥肥料品种的性质、粒度,干燥物料初含水份和终含水份,干燥机直径,扬料板的型式及布置方式,筒体转速,气流速度和气体进出口温度等因素有关,因此,A值的确定根据肥料品种和体系的有关工程数据来选用。

表2所列数据可作为选用时参考,由上列公式大略算出;A value has relative with character and size of dried fertilizer types、 original and final water content of dried material、diameter of dryer、type and arrangement form of flights、rotating speed of shell、gas flow speed and gas inlet and outlet temperature etc. factors; so A value shall be selected according to fertilizer type and relative engineer data of system; In table 2, all specified datas are for reference during selection; It can be preliminarily calculated as per the above formula. -3-干燥机水份蒸发强度Water evaporation strength of dryer物料名称Name of material初湿度(％)Original moisture终湿度(％)Final moisture进口气温(℃)Inlet gas temperature出口气温(℃)Outlet gas temperatureA(㎏水 water /m³h)普通过磷酸钙Ordinary peroxy calcium phosphate ～14 5～6 350～400 ～70 25～30低浓度复混肥料Low density compound fertilizer 5～7 ～3 ＜430 ～75 6～10中浓度复混肥料Mid-density compound fertilizer 5～7 ～2 ＜430 ～80 5～8高浓度复混肥料High density compound fertilizer 2～3 ＜1 ＜250 ～80 3～5注: 复合肥料体系众多,成份和配比复杂以及选用的加工工艺不同都会影响烘干能力,在选用时最好请专业的研究设计部门提供技术咨询意见。

Note: So many compound fertilizer system、complex composition and proportion as well as different machining process will affect drying capacity; During selection, it is better to request specifial research design department for submitting technical advisory opinion.四、结构特征及工作原理S。
