8、物料向磨盤邊緣移動(dòng)，經(jīng)過(guò)磨盤上的環(huán)形槽時(shí)受到磨輥的碾壓而粉碎，粉碎后的物料在磨盤邊緣被風(fēng)環(huán)處高速氣流帶起，大顆粒直接落到磨盤上重新粉磨，氣流中的物料經(jīng)過(guò)分離器時(shí)，在旋轉(zhuǎn)轉(zhuǎn)子的作用下，粗粉落到磨盤重新粉磨，合格細(xì)粉隨氣流一起出磨，在收塵裝置中收集，即為產(chǎn)品。含有水分的物料在與熱氣體的接觸過(guò)程中被烘干，達(dá)到所要求的產(chǎn)品水分。3、特 點(diǎn)（1） 物料主要是依靠磨輥的重量和加壓裝置的壓力被破碎和粉磨的，在粉磨過(guò)程中物料始終受到磨輥的壓力作用，而磨輥和磨盤間不是純滾動(dòng)，物料受到的是多向應(yīng)力的作用，因此提高了磨機(jī)的粉磨能力和粉磨效率。（2） 由于物料進(jìn)入磨機(jī)后就與熱氣體充分接觸，被粉磨后又懸浮在熱氣中，能充

9、分地進(jìn)行熱將交換。在粉磨的同時(shí)也烘干了物料。（3） 磨輥的碾磨壓力由液壓系統(tǒng)提供，通過(guò)加壓裝置、傳動(dòng)裝置傳給磨輥而施加 在物料上，通過(guò)調(diào)節(jié)液壓系統(tǒng)的壓力，來(lái)改變粉磨壓力的大小以滿足粉磨不同硬度物料的要求。（4） 為了避免磨機(jī)工作時(shí)因斷料磨輥與磨盤的直接接觸而造成的劇烈震動(dòng)，磨輥和磨盤之間應(yīng)有一定的間隙，因此，特別設(shè)計(jì)了控制間隙大小的限位裝置，并通過(guò)限位裝置可隨時(shí)了解磨輥下物料的厚度，因此保證了磨機(jī)在安全和經(jīng)濟(jì)的工作條件下運(yùn)行。（5） 輥套和磨盤襯板采用了高硬度合金耐磨材料，磨損小，壽命長(zhǎng)，而且當(dāng)輥套磨損到一定程度時(shí)，還可翻面使用，從而延長(zhǎng)輥套的使用壽命。（6） 磨輥能借助于輔助油缸的作用，將其

10、翻出機(jī)外，更換檢修非常方便。（7） 磨盤周邊上設(shè)有防止盤座磨損、調(diào)節(jié)風(fēng)環(huán)處風(fēng)速和盤上物料厚度的裝置，可確保立式磨的生產(chǎn)能力及其經(jīng)濟(jì)運(yùn)行。（8） 分離器由變頻器電機(jī)、減速機(jī)構(gòu)、轉(zhuǎn)子、殼體等部分組成。電機(jī)通過(guò)減速機(jī)構(gòu)帶動(dòng)分離器轉(zhuǎn)子轉(zhuǎn)動(dòng)，通過(guò)調(diào)整電機(jī)轉(zhuǎn)速而獲得不同細(xì)度的產(chǎn)品。（9） 主減速機(jī)由稀油站供油產(chǎn)生循環(huán)潤(rùn)滑系統(tǒng)，以保證主減速機(jī)的正常運(yùn)行。四、 工藝流程：hrm型原料立式磨在粉磨系統(tǒng)中的運(yùn)用主要有以下幾種形式，詳見工藝流程圖一、圖二。工藝流程圖一1.電子皮帶秤2.膠帶輸送機(jī)3.電磁除鐵器4.回轉(zhuǎn)鎖風(fēng)喂料機(jī)5.hrm型立式磨6.外循環(huán)提升7.高效旋風(fēng)收塵器8.風(fēng)機(jī)風(fēng)門9.主風(fēng)機(jī)10.氣箱脈沖收塵

34、 the data in the table of the stylebook is only provided for the selecting specification reference, the guarantee index of the equipment is basis on the signing contract.iii. operating principle1. the primary structure of hrm raw material vertical roller mill can be seen in the following drawing:1.

35、separating device; 2. middle shell; 3. grinding roller device; 4. driving arm; 5. limit device; 6. lower shell; 7. driving device; 8. hydraulic system; 9. auxiliary oil cylinder 2the operating principle is as follows: the motor drives the grinding disc to rotate by the reducer. the material falls in

36、to the center of the grinding disc from the inlet orifice, meanwhile the hot blast enters into the mill from the inlet opening, under the effects of the centrifugal force the material moves to the edge of the grinding disc, and then it is ground and pressed by the grinding roller while passing throu

37、gh the annular groove on the grinding disc, the crushed material is brought up by the high speed air jet in the vane at the edge of the grinding disc, the large granule directly falls into the grinding disc to be newly ground, while the material in the airflow passing through the separator and under

38、 the effects of the rotary rotor, the rough powder falls into the grinding disc to be newly ground, the eligible fine powder follows the airflow together coming out the mill, the products are collected by the dust collector. the material with the moisture which contacts with the hot gas is dried and

39、 reaches the permissible moisture of the products.3. features (1) the material is crushed and ground which is mainly depended on the weight of the grinding roller and the pressure of the pressure device. during the grinding process, the material is always under the effects of the pressure of the gri

40、nding roller, while between the grinding roller and the grinding disc is not the purely rolling, the material is under the multi-axial stress effects, so the grinding capacity and the grinding power of the mill are improved. (2) the materials get full contact with hot air after entering the mill, th

41、en they become powder and suspend in the hot air after been ground, as a result, they make full exchange with hot gas and so the materials are dried while being ground. (3) the grinding pressure of the grinding roller is provided by the hydraulic system, the pressure is brought to bear the material

42、through the pressure device and the driving device to pass into the grinding roller, the magnitude of the grinding pressure is transferred through adjusting the pressure of the hydraulic system to satisfy the requirements of grinding the materials with different hardness.(4) for avoiding the strenuo

43、us vibration which is created by the grinding roller contacting with the grinding disc directly during stopping feeding, there should be a certain clearance between the grinding roller and the grinding disc, therefore, so the limit device is specially designed for controlling the size of the clearan

44、ce, and through the limit device the depth of the material under the grinding roller can be realized at any moment, so the mill can be guaranteed in the safe and economical working conditions to operate. (5) the roller sleeve and the lining board of the grinding disc adopt the high hardness alloy we

45、ar resistant material, so the abrasion is small and the life is long, and while the roller sleeve is abraded into some certain degree, it can be turned to use, accordingly the useful time of the roller sleeve is prolonged. (6) the grinding roller can recur to the effects of the auxiliary oil cylinde

46、r; make it turn to the outside of the equipment, so the change and the maintenance & repair are very convenient. (7) the device that can prevent the disk base abrasion, adjust the wind speed of the vane and the thickness of the material on the disc are design at the edge of the grinding disc, so the

47、 production capacity and the economical operation can be guaranteed.(8) separator is made up of the frequency convertor motor, the reducer system, the rotor, the shell and so on. electric motor drives the rotor of the separator by the reducer system, and then gets the products with different finenes

48、s by adjusting the rotary speed of the motor.(9) the circulating lubricating system for the main reducer is produced by the oil supplying from the thin oil station, so as to ensure the normal working of the reducer. process flowthe handling of hrm raw material vertical roller mill in the grinding sy
