Why tiny air screen can achieve fine screening material

Air screen is a new screening mechanism of Professor Liang Xuezeng developed in the 1990s , the full use of the basic principles of fluid mechanics and dynamics , high

efficiency screening products in the new century . Its working principle can be roughly summarized as use of air buoyancy generated in the material suspension

Air , but also to the gas flow rate to a certain movement of the screen . Such use of air buoyancy of the material to a small cell floating in the air , while in the case of

velocity airflow mesh push to move away , to coal mining machine achieve the purpose of screening . Thus , the airflow can be achieved tiny sieve material or substance

Not the amount of the fine screening, screening also has high precision and speed advantages. Air screen widely used in chemical , food , building materials , paint and other

industries .
 Airflow sieve vibrating screen classifier major technical difficulty is how to get airflow design with a certain speed , while the device also has a certain tightness. Its flow is now the main way to get

there is to use a blower airflow source , through a certain pipe sizes to transform the speed of the airflow somewhat

Changed. When you need to change the speed of the airflow is large, typically driven by changing the blower motor speed to achieve.
