Description

Technical Field

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

[0002] Jigging machine refers to the equipment that realizes the jigging process. The material is mainly sorted according to the density difference in the vertically rising and falling variable speed medium flow. The difference in particle size and shape of the material has a certain influence on the mineral processing results. The medium used in jigging can be water or air. When water is used as the sorting medium, it is called hydraulic jigging; when air is used as the sorting medium, it is called wind jigging.

[0003] When the existing jig is in use, there are useless ores on the jig trough that are too large in size. Screening directly in the jig trough will cause wear on the platform on the jig trough, increasing the load of the jig. In addition, the existing jig drives the centrifugal turntable to rotate through a motor, thereby driving the two jig chambers to move up and down to complete the screening process. The vibration amplitude is small, and the material feeding speed is slow, which reduces the screening speed. Therefore, a movable jig screening device is proposed to solve the above-mentioned problems. Utility Model Content
