Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of screening machines, especially to a three-dimensional vibration screening machine. BACKGROUND

[0002] The three-dimensional vibration screening machine is also called a rotary vibration screen or a circular vibration screen. The screening machine uses a vertical motor as an excitation source, installs eccentric weights on the upper and lower ends of the motor, converts the rotary motion of the motor into three-dimensional motion in the horizontal, vertical and inclined directions, and then transmits the motion to the screen surface. By adjusting the phase angles of the upper and lower ends, the motion trajectory of the material on the screen surface is changed, so that the screening purpose is achieved. The three-dimensional vibration screening machine has the characteristics of preventing dust pollution, rotatable discharge port, convenient adjustment of the discharge position and low noise, and can screen various fine particle materials, fine powder, micro powder and dry and wet materials.
