Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a magnesium slag impurity classification and screening device. Background Art

[0002] Magnesium slag is the industrial waste residue produced during magnesium smelting. my country produces about 3.6 million tons of magnesium slag every year. Magnesium slag is a waste material produced during the production process of metallic magnesium. When it is taken out of the reduction tank, it still maintains a block shape. After natural cooling in the air, the surface gradually pulverizes into a fine powdery substance. When utilizing magnesium slag, it can be directly mixed with ground slag in a certain proportion, and a composite activator can be added to prepare a binder.

[0003] There will be some heavy metals and impurities mixed in the magnesium slag. When processing the magnesium slag, it is necessary to filter out the impurities or heavy metals mixed in it. When filtering the heavy metals in the magnesium slag, hydrogen peroxide will be used to oxidize the magnesium slag to improve the separation efficiency of heavy metals. After oxidation, the upper liquid is discarded, washed and dried, and finally citric acid and oxalic acid are used as eluents to rinse it to remove the heavy metals. However, after the removal, impurities will still remain in the magnesium slag. When filtering and screening the impurities in the magnesium slag, the magnesium slag is usually only screened once, which may cause insufficient filtration, and due to the different sizes of impurities in the magnesium slag, smaller impurities may still exist in the magnesium slag during screening.
