              設備組成與工作原理(Equipment composition and working principle)

                   流化床式氣流粉碎機由分級室、粉碎室及機架三大部件組成。分級室按電機驅動方式分有直聯式和并聯式兩種。按進料方式分有從分級室上部的斜管進入和由從粉碎室下部的噴射加料器強制進入兩種。物料進入粉碎室,壓縮空氣通過粉碎噴嘴激劇的膨脹加速產生的超音速噴射流在粉碎室下部形成向心逆噴射流場,在壓差的作用下,使磨底物料流態化,被加速的物料在多噴嘴的交匯點匯合,產生劇烈的沖擊、碰撞、摩擦而粉碎。被粉碎的細粉隨氣流一起運動至上部渦輪分級輪處,在離心力的作用下粗粉被甩至筒壁,繼續粉碎,符合細度要求的微粉從排氣管排出。粉碎室的進料按分級電機的電流及噴射器的壓力來調節加料速率,使粉碎始終處于最佳的工作狀態。

              The fluidized bed jet mill composed by classify chamber, grinding chamber and support. Classification chamber has straight and parallel-coupled by the way of the motor drive. According to the way of feeding there are inclined tube feeding from the up of classification chamber and the feeding by injection feeder of down of grinding chamber. As raw materials get into grinding chamber, forming a centripetal reverse jet flow field by supersonic jet which formed by compressed air accelerated by the rapid expansion of grinding nozzles, under the differential pressure force, so that the end of grinding material fluidized, the materials is accelerated at the confluence of multi-nozzle intersection, have a dramatic impact, collision, friction and grinding. The fine powder crushed together with the air flow moved to the turbo classifier wheel, the coarse powder thrown to the cylinder wall under the centrifugal force to regrind, comply with the requirements of fineness powder discharged from the exhaust pipe. The feed rate of crushing chamber can be adjust by a feed motor current and the pressure of the classification injector, so that the grinding is always in the best working condition.

              性能特點(Performance characteristics)

              本機集粉碎、分級、混合、均化機理于一體,實現聯機作業獨特的優點,因此具有以下特點:

              The machine crushing, grading, mixing, homogenizing mechanism in one, the unique advantages of the online operation, it has the following characteristics

               

              1. 沖擊速度高,顆粒受到氣流噴嘴加速后對沖撞擊,撞擊速度是兩相對速度的疊加,粉碎效率高。

              2. 能耗低,與其他形式的氣流磨相比,可節能30-40%。

              3. 磨損小,由于顆粒是在流化床中相互沖擊和碰撞,顆粒很少碰撞筒壁及物料不通過噴嘴,故適用于硬物料的粉碎。

              4. 內設的渦輪分級機分級精度高,產品粒度分布窄,粒徑調節方便。

              5. 適用范圍寬,可粉碎熱敏性物料。

              6. 結構緊湊,占地面積與傳統氣流磨相比減少3-6倍,體積小6-10倍。

              7. 設備清掃容易,粉碎品種變更方便。

              1.High impact velocity, the particles are subjected to hedge impact  accelerated airflow nozzle, the impact velocity is two superimposed of the relative velocity , high crushing efficiency.

              2.Low energy consumption, compared to other forms of jet mill, energy saving 30-40%.

              3.Wear, because the particles are crushed in a fluidized bed and mutual impact collisions, particles rarely collide cylinder wall and material not through the nozzle, it is suitable for hard materials.

              4.Turbo Classifier offers high precision, narrow particle size distribution, particle size easy to adjust.

              5.Wide range application, heat-sensitive materials can be crushed.

              6.Compact structure an area compared to traditional jet mill to reduce 3-6 times, small 6-10 times

              7.Equipment cleaning easy, easy to change varieties crushed

              適用范圍(Applications)

              該機能廣泛應用與化工、冶金、非金屬礦、電子、醫藥、農藥、顏料、食品、化妝品等行業。

              The machine can be widely used in chemical industry, metallurgy, non-metallic minerals, electronics, pharmaceuticals, pesticides, paints, food, cosmetics and other industries.
