JL VORTEX AIR CLASSIFIER PROCESS (SECONDARY CLASSIFICATION)JL渦流氣流分級機工藝流程示意圖(二次分級)

產品用途/ PRODUCT PURPOSE

目前大多數的粉體生產設備所加工的粉體多為粒徑比較分散的混合粉，而在實際應用中，只有某一粒度區間或某一粒度段的粉體，才能滿足用戶的需求。分級機就是從混合粉體中按照某一粒度區間值金星超級粉體分選的設備。它可以與一般的粉碎設備（如球磨機、雷蒙機、氣流磨、沖擊磨等）聯合使用分選出所需求的細粉，及時清除粉料中過粗或過細的顆粒，有效地解決夾帶現象而達到控制粒徑分布的目的。

物料經給料機投入分級后，被分級的物料先經過預選區，使顆粒完全分散。在分級渦旋力的作用下，粗細粉分離。滿足粒度要求的細粉經過分級輪進入細粉捕集系統。粗粉及團聚狀細粉降至二次進風處，由此葉柵產生的漩渦離心上升氣流對物料進行強烈沖洗。使粗細粉再次分離，細粉隨著上升氣流進入分級區，粗粉降至一次進風處，接受一次進風氣流的強烈沖洗，純凈的粗粉被排出機外。臥式分級輪具有精確的頂點切割尺寸，可保證細粉中不含大顆粒。本分級機具有非常高的分級精度、效率和細度。

At present, most of the powders processed by powder production equipment are mixed powders with relatively dispersed particle sizes. But in the practical applications, only the powder of a certain granularity interval or a certain granularity segment can satisfy the user's demand. The classifier is a device sorting Venus super powders from mixed powders according to a certain granularity interval. It can be combined with the general crushing equipment (such as ball mill, Raymond mill, jet mill and impact mill) to separate the required fine powder and remove excessively coarse/fine particles of the powders in time, effectively solving the entrainment phenomenon to achieve the purpose to control the size distribution of particle. 

After the materials are put into classification by the feeder, the classified materials first pass the pre-selection section, making the particles dispersed completely. The coarse and fine powders are separated under the force of graded vortex. Fine powders meeting the requirements of particle size enter the trapping system of fine powder through the stepped gear. Coarse powders and agglomerated fine powders fall to the secondary air inlet, and the centrifugal updraft in vortex generated by the cascade strongly flushes the materials. The coarse and fine powders are separated again. The fine powders enter into the stepped section along with the updraft, and the coarse powders drop to the primary air inlet, receiving the strong flushing of airflow in the primary air inlet, and making the pure coarse powders discharged out of the machine. The horizontal stepped gear has accurate vertex cutting size, which can ensure that the fine powder does not contain large particles. This classifier has very high classification accuracy, efficiency and fineness.
