Description

Technical Field

[0002] The rotary vibrating screen is a high-precision fine powder screening machine with low noise, high efficiency, and fast screen change in 3-5 minutes. It has a fully enclosed structure and is suitable for screening and filtering of materials such as particles, powders, and mucus. The rotary vibrating screen uses an upright motor as the excitation source. An eccentric weight is installed at the output end of the motor to convert the motor's rotational motion into horizontal, vertical, and inclined three-dimensional motion, and then transmit this motion to the screen surface. By adjusting the phase angle at the upper and lower ends, the motion trajectory of the material on the screen surface can be changed.
