The length of the screen surface was 160 mm and it was evenly divided into eight parts so the relationship between screen length and screening efficiency could be analyzed. 3.2. Screening efficiency versus screen length: varied frequency and vibration angle. Frequency mainly influences the bounce state of particles on the screen surface.
Screening efficiency depends on the length of the screen surface, the screen surface long high screening efficiency. Generally an aspect ratio of 2. Effective screening area (ie, mesh area and the entire screen surface area ratio) the greater the productivity per unit area of the screen surface and higher screening efficiency.
