Description

Metal refining agent powder crushing and screening device

Technical Field

The utility model relates to the technical field of crushing and screening, in particular to a metal refining agent powder crushing and screening device.

Background Art

Refining agent is a white powder or granular refining agent, which is made by mixing a variety of inorganic salts in a certain proportion after drying. It is mainly used to remove hydrogen and floating oxide slag inside the aluminum liquid. Refining agent is mainly used to remove hydrogen and floating oxide slag inside the aluminum liquid, making the aluminum liquid purer, and also has the function of slag removal agent.

Before the refining agent is processed and used, it needs to be crushed and screened to a certain mesh size so that it can be added to the molten metal for use. However, the crushing and screening work needs to be carried out separately at present, and it is easy to cause spillage during the transportation process, and it is difficult to clean up and reuse it after spilling, which leads to great waste. In addition, too much coarse material will be screened out during the screening process, and it must be crushed again before it can be screened and used. After receiving the material, it needs to return to the crusher for crushing, and it also needs to be transported, which also causes a great waste of time, greatly affecting the processing of the refining agent and the efficiency of the factory.
