Speaking of the airflow classifier, it is no longer unfamiliar for people now, it is a device for fine screening of ultrafine powder materials, widely used in modern industries. There are many models of the airflow classifier, which is representative of the FW series airflow classifier, its precision, efficiency, and stability above the same type of equipment.
The airflow classifier is a device that grants the material using the traction force generated by the centrifugal force and the airflow of the impeller. The seal between the rotating cage rotor and the stationary housing is an important part of the eddy current air grade machine structure, which is an important reason for the product fineness or finished product mixed into part of the crude particles. So what are the sealing methods of airflow classifiers? Let's take a look.
(1) Airflow Sealed
The normal turbine classifier is usually rising through the high-speed rotary suppression particles of the grading wheel to the top end of the classified wheel, theoretically, the sealing effect can be achieved, and the domestic horizontal grade machine is mostly The airflow seal is used, but the large particle leakage of the classification wheel cannot be strictly controlled, and the gas consumption has gradually increased due to wear.
(2) Mechanical seal
mechanical seals can be divided into embossed seals, which adjusts gap seals and labyrinth seals.
The main principle of the labyrinth seal is to ensure the sealing effect by controlling the sealing gap, but due to its gap, the particles of the parties are never or even millimeters have not passed the finished finished product, so The sealing effect of mechanical maze seal in the ultrafine classifier is not good.
This is visible, the airflow classifier uses a pressure differential air flow sealing structure, with high level of grading accuracy, energy saving, efficiency and production cost, and has been obtained in the process of grading in quartz, longite, mica, kaolin, magnesium oxide. widely used. Shandong ALPA Powder Technology has always firmly convinced that the basis of the global brand is the improvement of product and service quality, and behind the quality of the quality is a fear of market. Under the line, from a single channel to multi-dimensional propagation, from China to overseas, Shandong AlPa powder technology has always been combined with dealers, the user's demand is centered, and the quality improvement is based on the construction of globalization. The powder equipment brand is a vision, continuously striding forward, and has achieved a new breakthrough, and a strong "Chinese voice" in the industrial powder equipment field.
