The double-layer banana sieve is mainly used for coal grading, desliming, dehydration and de-intermediation, and also suitable for the screening and grading of other minerals. The double-layer banana screen includes side panels, vibration exciters, motors, belt drives, auxiliary shaft pairs, buffer springs, upper sieve plates, lower sieve plates, excitation beams, upper beams, lower beams, lifting beams, etc. Double-layer vibrating sieve for banana sieve. The upper sieve plate has a large inclination angle, and the lower sieve is basically arranged horizontally. This structure can efficiently process a large amount of feedstock through thin-layer screening. The feed material passes through the upper sieve plate at a high speed to make the powder material get preliminary separation. The material moves at high speed on the sieve plate to separate it into thin layers. Maintenance of banana sieve Before installation, it is necessary to check whether the parts are intact and complete, and ...
