Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, and in particular to a novel flotation machine dispersion hood and flotation machine. Background Technology

[0002] The slurry is agitated in the flotation machine, combined with reagents, and then bubbles are generated by passing through the holes in the dispersion hood. Older dispersion hoods were made of 10mm rubber sheets, which are prone to deformation and breakage, and the rubber material ages easily over long periods. The flotation machine is a continuously operating device, and the orifices of the dispersion hood are constantly eroded by the slurry, leading to wear and a short service life. Enlarging the orifices results in poor flotation performance and a significant reduction in foam production, impacting production. The original dispersion hood was a split type, with two semi-circular rings horizontally secured with 12mm bolts, using the bolt tension to hold the two halves to the stator. In actual use, this installation method is not secure and is prone to loosening or damage, causing the dispersion hood to detach and requiring machine shutdown. Utility Model Content
