气流粉碎分级机,多级串联分级机工作原理:
多个分级机与除尘器、引风机组成一套气流粉碎分级机分级系统。物料在风机抽力作用下由分级机下端入料口随上升气流高速运动至分级区,在高速旋转的分级涡流产生的强大离心力作用下,使粗细物料分离,符合粒径要求的细颗粒通过分级轮叶片间隙进入旋风分离器或除尘器收集,粗颗粒夹带部分细颗粒撞壁后速度消失,沿筒壁下降至二次风口处,经二次风的强烈淘洗作用,使粗细颗粒分离,细颗粒上升至分级区二次分级,粗颗粒下降至卸料口处排出。

Working principle:
A classification system is composed of a classifier, a dust collector and a draft fan. The material suction force under the action of the fan by the lower inlet classifier with the updraft speed to the classification area, strong centrifugal force generated in the high-speed rotation of the turbine grade, the thickness of material separation, meeting the size requirement of fine particles by classifying blade gap into the cyclone separator or dust collection, disappear the speed of the coarse particles entrained fine particles hit the wall, along the cylinder wall decreased to two times after two times the wind outlet, strong washing effect, the particle separation of fine particles up to two grade grade area, coarse particles down to the discharging port at discharge.
Performance characteristics:
1, without water, washing, completely dry production, can obtain a narrower particle size distribution and pollution free abrasive powder; a classification according to the current domestic and foreign standard processing into any brand (such as: GB W63 ~ W3.5, Japanese standard 240#~3000, European standard F230/53 ~ F1200/3). Single rate of finished products reached more than 75%.
2, high classification accuracy, cutting particle size more accurate, lower speed required, long service life.
3, independent casting bearing seat, never deformation, long service life.
4,the optimized transmission design, the axle bears the force small, the service life is long.
5, unique pipeline design, to help powder flow, and help to reduce wear and tear, easy to wear parts, easy to change and deal with.
6, the company unique frequency conversion feeding system, to help the dispersion of materials, can guarantee the continuous, uniform and stable feeding, to help product particle size control.
7, unique internal circulation, two times wind design, classification cone gap adjustable, gas consumption greatly reduced, so that classification energy consumption reduced, fine powder extraction thoroughly.
8, the separation of the flow path will help to reduce the wear of the bottom of the grading wheel, and more conducive to the control of large particles.
