The QS series air flow sieve is a high-precision screening equipment that screens fine powders with a mesh, widely used in industries such as chemical, pharmaceutical, food, papermaking, metallurgy, building materials, rubber, and machinery. It can effectively screen powdered materials with a fineness range of 80-500 mesh continuously. This air flow sieve has high screening efficiency, large output, precise fineness, and no over diameter mixing phenomenon. The screen mesh is vertically installed without load and can be replaced freely, with a long service life. It is suitable for a wide range of fineness, fully enclosed structure, no dust overflow, low noise and energy consumption, can operate continuously, and is easy to maintain.Basic Structure of QS Series Airflow Screen:The airflow screen and gas-solid separation dust removal device form a closed-loop screening system. The host is an air flow powder screening machine, and the closed shell of the screening body is equipped with a vertical circular cylindrical screen mesh; The inner side of the screen has a circular wind turbine, which is driven to rotate by an electric motor mounted on the base; The upper part of the screen shell is equipped with a feeding hopper and a coarse screen, and the lower part is equipped with a slag discharge port; The motor is connected to the spindle via a belt; The lower opening of the wind turbine hopper forms a feeding gap. The gas-solid separation and dust removal device consists of an induced draft fan, a settling chamber, and a dust removal bag. The airflow screen is connected to the separation and dust removal device by a plastic corrugated hose.The main features of QS series airflow screen are:1. The screening efficiency is high, reaching over 95%, and the hourly output is 5-10 times or higher than that of vibrating screens;2. It is suitable for a wide range of fineness and can efficiently screen powder materials ranging from 8 O to 5 3 O;3. The product has precise fineness, no super mixing phenomenon, the screen mesh is installed vertically, no load, and has a long service life;4. The screening program is carried out in a negative pressure half cycle state, without dust pollution, and can be used in conjunction with various mills and air ducts;5. Low noise, low power consumption, continuous operation, and reduced maintenance.QS series airflow screening machine technical parameter table:参数气流量      m3/h筛网规格目有效筛面      m2**大入料粒度目筛机功率      KW主轴转速      rpm筛机外径      mm筛机高度      mmQS-600240100            至            5000.640            至            602.214506001250QS-10003600.95.598010081700QS-12004302.97.596012002400QS-15004803.71145015002550Application examples of QS series airflow screening machine:物料名称工作方式筛网（目/寸）QS-1000处理量      （kg/h）QS-1500处理量      （kg/h）轻钙干式120-180600-10001000-2000重钙干式400600-10001000-2000活性钙干式500600-10001000-2000山渣粉干式300600-10001000-2000淀粉干式300600-10001000-2000锌粉干式325600-10001000-2000粉煤灰干式120-200600-10001000-2000氧化铁黑干式500600-10001000-2000氧化铁红干式500600-10001000-2000中药粉干式120-160600-10001000-2000石英粉干式180-270600-10002000-3000面粉干式100-180200-300500-1000木粉干式100-300200-300500-1000云母粉干式300-400200-300500-1000
