Abstract
Description
Technical Field
[0001] This utility model relates to the field of iron powder production technology, and in particular to an iron powder stirring device. Background Technology
[0002] Iron powder is one of the basic raw materials in the powder metallurgy industry. Due to its large specific surface area and activity, it has special properties such as electrical, magnetic, optical, catalytic, adsorption and chemical reactivity. In the production process, iron powder needs to be mixed with additives. In order to ensure that the mixture is uniform, a stirring device is required to stir the iron powder.
[0003] Existing iron powder mixing devices often break up and mix the iron powder before feeding it directly. In order to facilitate operation, the feeding end of the iron powder mixing device is often directly connected to the conveyor belt. This can easily lead to the iron powder clumps being directly transported to the next step by the conveyor belt, which will affect subsequent operations due to the clumping of iron powder.
