Description

Technical Field

[0001] The utility model relates to the technical field of mining screening devices, in particular to a mining screening device. Background Art

[0002] The vibrating screen works by utilizing the reciprocating vibration generated by the excitation of the vibrator. The upper rotating hammer of the vibrator causes the screen surface to produce planar gyratory vibration, while the lower rotating hammer causes the screen surface to produce conical gyratory vibration. The combined effect causes the screen surface to produce complex gyratory vibration, and its vibration trajectory is a complex spatial curve. However, the existing vibrating screen is only suitable for some small ores and cannot crush and screen larger ores, which reduces the practicality of the device. Therefore, we propose a mining screening device that can screen out fine ores and crush large ores. Utility Model Content
