Industrial cocoa bean vibrating screener/Cocoa beans separactor/Screening machine for cocoa powder, also known as three-dimensional vibrating screen or three-dimensional vibration, is a high-precision fine powder screening machine with low noise and high efficiency, which is suitable for screening and filtration of granules, powder, mucus and other materials. Its basic principle is to install a vertical motor to provide excitation force for the screen machine, and eccentric weights are installed at the upper and lower ends of the motor to convert the rotary motion of the motor into horizontal, vertical, and inclined three-dimensional motion, and then convert this motion. It is passed to the screen surface, and the material is screened on the screen.
