Description

Technical Field

[0001] The utility model relates to the technical field of flotation reagent processing equipment, and more particularly to a flotation reagent low-temperature pretreatment device. Background Art

[0002] During the flotation process, the pulp temperature has a significant impact on the flotation effect. Properly increasing the flotation pulp temperature can significantly increase the flotation speed and obtain higher flotation indices. This is because when the temperature rises, the effects of activators and depressants are enhanced, the reaction is accelerated, and thus the flotation effect is improved. However, when the temperature drops, the effects of activators and depressants will weaken, resulting in a decrease in flotation index. Low-temperature pretreatment flotation reagents can overcome the problem of decreased flotation effect under low temperature conditions.

[0003] In the prior art, for example, patent number CN202321240472.5, titled "A Patent for Low-Temperature Pretreatment Equipment for Flotation Collectors," requires that the material be introduced into the low-temperature equipment during low-temperature pretreatment of the flotation agent, and that it be exported after the treatment is completed. This cumbersome workflow affects work efficiency.
