Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screen equipment, in particular to a vibrating screen for mining and screening. Background Art

[0002] The vibrating screen works by using the reciprocating vibration generated by the vibrator excitation. The upper rotating weight of the vibrator causes the screen surface to produce a plane gyration vibration, while the lower rotating weight causes the screen surface to produce a conical gyration vibration. The combined effect causes the screen surface to produce a complex gyration vibration. Its vibration trajectory is a complex space curve. The curve is projected as a circle on the horizontal plane and an ellipse on the vertical plane. The amplitude can be changed by adjusting the exciting force of the upper and lower rotating weights. And adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the screen surface motion trajectory and change the motion trajectory of the material on the screen surface.

[0003] At present, when the vibrating screen for mining screening is screening the mineral materials, the screen of the vibrating screen often directly contacts the mineral materials. When the mineral materials contain high mud and water content, the screen holes of the vibrating screen are often blocked by the mineral materials, and the mineral materials that continuously enter will continue to accumulate at the blocked part of the vibrating screen, thereby affecting the quality and efficiency of the vibration screening of the mineral materials. For this reason, we propose a vibrating screen for mining screening. Utility Model Content
