QS系列气流筛分机(气流筛)产品概述：
QS型气流筛分机是一种对微细粉进行有网筛分的高精度筛分设备，广泛应用于化工、医药、食品、造纸、冶金、建材、橡胶、机械等行业。可对细度范围在80-500目内的粉状物料很好的连续筛分。气流筛筛分效率高、产量大，细度精确、无超径混级现象，筛网立装不荷重且可任意更换、使用寿命长，适应细度范围广，全封闭结构，无粉尘溢散，噪音小能耗低、可连续作业，维修方便。
气流筛广泛应用于各种难筛微细粉，50-500目范围内的细粉都能很好的筛分。如轻钙粉、活性钙粉、活性碳粉、淀粉、中药粉、粉煤灰、锌粉、石墨粉、石英砂粉、金粉、陶土粉、山楂粉、果疏粉、氢氧化钙粉、农药粉、魔芋粉、荧光粉、木粉、面粉、环氧树脂粉、二氧化锰、硫磺粉、氧化铝粉、胶木粉、氧化镁、珍珠岩粉、铁粉、棉短绒等。气流筛粉机是一种有网筛分和分级设备，不是磨粉机。其喂料机的粉碎功能只是对成团的粉块打碎利于过网，并无研磨功能。因此在选择气流筛粉机筛选某种细度的细粉时，首先要知道其中含有多大比例的该细度的细粉，如果其细度只有200目，想筛出325目细度的细粉是不可能的。气流筛的特点是筛细不筛粗，块状及颗粒状的物料适合用振动筛进行分级。
Product overview
QS type airflow screen machine is a kind of high accuracy of the mesh points on micro powder sieving equipment, widely used in chemical, pharmaceutical, food, paper making, metallurgy, building materials, rubber, mechanical and other industries.To fineness range within 80-500 mesh powder material is very good for screening.Air flow high screening efficiency, large output, precise fineness, without super size mixing phenomenon, screen mesh made with no load and can be arbitrary replacement, long service life, suitable fineness range is wide, fully closed structure, no dust overflow scattered, continuous operation, low energy consumption, little noise easy maintenance.
Airflow screen is widely used in all kinds of difficult to screen fine powder, within the scope of 50-500 mesh powder can be very good sieving.Such as the light calcium powder, activated calcium powder, activated carbon powder, starch, powder, fly ash, zinc powder, graphite powder, quartz powder, gold powder, clay powder, hawthorn powder, fruit powder, calcium hydroxide powder, pesticide powder, konjac powder, fluorescent powder, wood powder, flour, epoxy powder, manganese dioxide, sulfur powder, alumina powder, bakelite powder, magnesium oxide, perlite powder, iron powder, cotton linter, etc.Airflow sieving machine is a kind of network screening and grading equipment, not a flour mill.The crushing function of the feeding machine is broken on the clouds of powder block to a network, no grinding function.So in the selection of airflow sieving machine a fineness of the powder, the first thing to know that it contains much proportion of the fineness of the powder, if its fineness of 200 mesh only, want to screen out of 325 mesh fineness of fine powder is impossible.Airflow sieve sieve is the feature of fine sieve coarse, block and granular materials suitable for grading vibrating screen.
QS系列气流筛分机(气流筛)产品工作原理：
气流筛分机摈弃重力势能作业原理，采用空气作载体，动能作功的作业原理。通过负压气流将物料与空气混合后，进入筛机风轮中间，通过风轮叶片施加足够的离心力，向桶型筛网喷射过网，经过蜗壳收集。超径物料不能过网，由自动排渣口排出，从而达到快速筛分之目的。该机适合80-530目有网各种粉状物料筛选分级，其筛分效率高、产量大、自动进料排料、连续作业、无污染，使以往用各种振动筛难以进行高细度精密筛分作业成为易事。经过对120-180目轻钙、300目重钙、400目活性钙、300目山楂粉、320-500目锌粉、500目氧化铁黑、氧化铁红、120-160目中药粉、180-270目石英粉等物料的筛分使用，测得每平方米筛网面积每小时产量均在一吨左右，同时测得筛分效率在95%以上，空气含尘量低于10mg/m3。
Working principles
Airflow screen machine devoid of gravitational potential energy principle of operation, using air as the carrier, kinetic energy of the operation principle of work.By negative pressure air after material is mixed with air, among screen machine rotor, passing pressure rotor blades enough centrifugal force, the screen mesh to the bucket injection network, through the collection.Super size material cannot pass network, is being exhausted from port self-discharging, so as to achieve rapid screening of purpose.This machine is suitable for all kinds of powder material has a small net at one 80-530 mesh screen classification, its high screening efficiency, large output, automatic feed discharging, continuous operation, no pollution, make the past with a variety of vibrating screen to a high fineness of precision screening operation become easy.After light calcium in 120-180 mesh, 300 mesh coarse whiting, active calcium and 400, 300 mesh hawthorn powder, 320-500 mesh zinc powder, 500 mesh, iron oxide red, iron oxide black powder in 120-160 mesh, 180-270 mesh sieve using quartz powder or other materials, measured per square metre screen area around a tonne output per hour, screening efficiency can be measured in more than 95% at the same time, the air dust content less than 10 mg/m3.Airflow sieving machine devoid of gravitational potential energy principle of operation, using air as the carrier, kinetic energy of the operation principle of work.By negative pressure air after material is mixed with air, among sieve machine rotor, by pressure rotor blades enough centrifugal force, the screen mesh to the bucket injection network, through the collection.Super size material cannot pass network, is being exhausted from port self-discharging, so as to achieve rapid screening of purpose.This machine is suitable for all kinds of powder material has a small net at one 80-530 mesh screen classification, its high screening efficiency, large output, automatic feed discharging, continuous operation, no pollution, make the past with a variety of vibrating screen to a high fineness of precision screening operation become easy.After light calcium in 120-180 mesh, 300 mesh coarse whiting, active calcium and 400, 300 mesh hawthorn powder, 320-500 mesh zinc powder, 500 mesh, iron oxide red, iron oxide black powder in 120-160 mesh, 180-270 mesh sieve using quartz powder or other materials, measured per square metre screen area around a tonne output per hour, screening efficiency can be measured in more than 95% at the same time, the air dust content less than 10 mg/m3.
