工作原理

流化床氣流粉碎機(jī)（下文稱氣流磨）是一種利用高速氣流來實(shí)現(xiàn)干式物料粉碎的設(shè)備。它由磨體、噴嘴、分級(jí)機(jī)等部分組成，物料通過進(jìn)料口進(jìn)入磨體內(nèi)部粉碎區(qū)，壓縮空氣通過超音速噴嘴向磨體內(nèi)高速噴射，粗顆粒在超音速的噴射氣流中加速，并在噴嘴的交匯處對(duì)撞粉碎。被粉碎物料隨上升氣流進(jìn)入分級(jí)區(qū)，在分級(jí)機(jī)的作用下，大于分級(jí)粒徑以上的粗顆粒物料返回磨體內(nèi)部繼續(xù)沖擊粉碎，符合分級(jí)粒徑的細(xì)顆粒成品，則通過分級(jí)輪經(jīng)過管路進(jìn)入除塵器收集，微粉收集系統(tǒng)由粉塵收集器構(gòu)成。超細(xì)粉通過密封管道進(jìn)入收塵器后，由排料系統(tǒng)排出包裝即是成品。粉塵進(jìn)入粉塵收集器，通過布袋過濾（德國必達(dá)福濾袋）后的氣體，在引風(fēng)機(jī)的作用下抽出，尾氣排入大氣中。其排放的粉塵量低于國家的環(huán)保部門規(guī)定的粉塵排放標(biāo)準(zhǔn)。

Working principle

Fluidized bed airflow Grinder (hereafter referred to as Air Mill) is a kind of equipment which uses high speed air flow to realize dry material crushing. It consists of grinding bodies, nozzles, classifiers, etc. The material enters the grinding area through the inlet of the material, the compressed air is injected into the grinding body at high speed through the supersonic nozzle, and the coarse particles are speeded up in the supersonic jet flow. And smashing at the junction of the nozzle. When the comminuted material enters the classification area with the updraft, under the action of the classifier, the coarse particle material larger than the classifying diameter returns to the grinding body and continues to impact and comminute. The dust collection system consists of dust collector. After the super-fine powder enters the dust collector through the sealing pipe, the packing is finished product by the discharge system. The dust enters the dust collector, filters the gas after the cloth bag (the German Bedafur filter bag), pulls out under the action of the induced fan, the tail gas is discharged into the atmosphere. The amount of dust emitted is lower than the dust emission standard set by the national environmental protection department.

性能優(yōu)勢

1.    分級(jí)機(jī)采用新的技術(shù)，特殊設(shè)計(jì)的分級(jí)機(jī)，比原有的分級(jí)機(jī)阻力低30%以上，相應(yīng)降低風(fēng)機(jī)能耗20-30%，

粒度分布集中，避免了機(jī)內(nèi)粉體的過粉磨，與老型氣流磨相比節(jié)能20~30%，產(chǎn)量高出30~40%。

2.    采用獨(dú)立設(shè)計(jì)的分級(jí)機(jī)主軸結(jié)構(gòu)，全新的結(jié)構(gòu)設(shè)計(jì)擁有更高的強(qiáng)度，更高的轉(zhuǎn)速，更長的使用壽命，更加方便的潤滑及保養(yǎng)，采用Honeywell或者SIEMENS高能效電機(jī)驅(qū)動(dòng)，各個(gè)方面都超過采用電動(dòng)機(jī)直聯(lián)的方式。

3.    系統(tǒng)操作采用觸摸屏界面來進(jìn)行操作，PLC程序自動(dòng)控制，分級(jí)機(jī)，主風(fēng)機(jī)，給料機(jī)全部采用日本安川變頻器驅(qū)動(dòng)控制，給料系統(tǒng)能夠根據(jù)系統(tǒng)壓差，電流等數(shù)據(jù)進(jìn)行更加快速、準(zhǔn)確的給料。脈沖收塵器的清灰控制，主風(fēng)機(jī)的轉(zhuǎn)速控制全部根據(jù)系統(tǒng)的壓力，壓差進(jìn)行全自動(dòng)的控制，來確保整個(gè)系統(tǒng)穩(wěn)定、高效的運(yùn)行。

4.    磨損小。由于主要粉碎作用是物料之間的相互沖擊碰撞，高速的物料顆粒與磨體內(nèi)壁很少碰撞，可適用粉碎莫氏硬度九級(jí)以上的物料。

5.    對(duì)易燃、易爆物料可用惰性氣體做工質(zhì)粉碎。

6.    無污染。因?yàn)槲锪鲜窃跉饬鞯膸?dòng)下自身碰撞粉碎，不帶入介質(zhì)，這樣在物料的粉碎過程中不會(huì)構(gòu)成污染。

7.    產(chǎn)量:50～5000 kg/h；細(xì)度：d97=3～45μm；

Performance advantage

1. The classifier adopts new technology. The specially designed classifier is more than 30% lower than the original classifier, which reduces the energy consumption of the fan 20-30, and concentrates the particle size distribution, thus avoiding the grinding of the powder in the machine. Compared with the old type of air mill, energy saving 20, 30, the output is higher than 30, 40.

2. The new structure has higher strength, higher speed, longer service life, more convenient lubrication and maintenance, and is driven by Honeywell or SIEMENS high energy efficiency motor. All aspects go beyond the direct connection of the motor.

3. The system uses touch screen interface to operate, PLC program automatic control, classifier, main fan, feed machine are all controlled by Igawa inverter, feed system can be more quickly based on system pressure difference, current and other data. Accurate feed. In order to ensure the stable and efficient operation of the whole system, the ash cleaning control of the pulse dust collector and the speed control of the main fan are carried out automatically according to the pressure and pressure difference of the system.

 4. Wear is small. Because the main comminution action is the impact and collision between the materials, the high speed material particles rarely collide with the grinding body wall, so it can be used to comminute the materials with Mohlich hardness above nine grades.

5. Flammable and explosive materials can be comminuted by inert gas.

6. No pollution. Because the material is driven by the airflow, it does not bring into the medium, so the material will not be polluted in the process of crushing.

7. Yield: 50kW 5000 kg/h; fineness: d97m 3N 45 μ m;
