Description

Technical Field

[0001] The utility model relates to the technical field of collector production equipment, in particular to a feeding device for vanadium-titanium magnetite collector. Background Art

[0002] A collector is a flotation reagent that changes the hydrophobicity of the mineral surface and makes the floating mineral particles adhere to the bubbles. It is the most important type of flotation reagent. It has two basic properties: it can selectively adsorb on the mineral surface and can increase the hydrophobicity of the mineral surface, making it easy to adhere to the bubbles, thereby improving the floatability of the mineral. The mixing of collectors is an important workflow.

[0003] During the production of collectors, according to different customer requirements, the collectors need to be mixed and then packaged. Since the collector has a certain viscosity, it is generally fed by relying on its own gravity or a liquid pump. Feeding by gravity takes a long time and has low production efficiency. Feeding by a liquid pump not only produces high noise but also consumes a lot of energy. In order to avoid cross-contamination, one pump for one material is also used, which increases the production and maintenance costs.
