According to the different uses and processing capacity of the sieve, the sieve adopts different sieving area, sieve slit size, number of sieve surface segments and sieve surface inclination angle. It is divided into single-layer banana screen and double-layer banana screen, with a working area of 5.7m2~ 30.2m2, a total of 20 main specifications and models, which can basically meet the production needs of various types of mines and coal preparation plants.
The principle of equal-thickness screening is applied, and different vibration parameters, the number of segments and the inclination angle of the screen surface are adopted for different material characteristics. The inclination angle of the screen surface is too gentle, and the number of screen surface segments is 4~7, which can ensure the best screening process effect. At the same time, the gentle excessive inclination angle and the large number of segments are beneficial to the improvement of the life of the screen surface.
