The V-type classifier is a coarse powder grading equipment specifically designed for the grinding characteristics of disk mills, suitable for separating products with particle sizes of 0~1mm, 0~1.5mm, and 0~2mm. It overcomes the shortcomings of centrifugal and rotor classifiers, which can only select fine powders, and vibration screens, which are only suitable for screening coarse particles, have low efficiency for fine particles, and are prone to screen clogging and frequent replacement. In practical applications, this system features negative pressure circulation, compact layout, low noise, and minimal dust emission, making it the most**performant coarse powder sorting equipment available globally.

Working Principle

This unit employs a working principle combining gravity and wind classification. Airflow is generated by the matching fan and enters the machine through the inlet. It comes into contact with the material, which has been dispersed by the dispersing plate and fed into the inlet. The fine powder in the material is affected by gravity less than the horizontal force brought by the airflow, so it is carried away by the airflow through the outlet and enters the collection system as finished product. The coarse powder in the material is slightly less or equivalent to the horizontal force brought by the airflow due to gravity, and the airflow force is not enough to carry it to the outlet. Therefore, it produces a certain horizontal displacement and passes over the regulating plate through the middle outlet. Large pieces of material with high volume and weight are affected by the airflow force with minimal horizontal displacement, so they fall directly into the outlet and are discharged.
