Technical Field
[0001] The utility model relates to the technical field of crushing equipment, in particular to a red mud crushing and extraction device. Background Art
[0002] Red mud is an industrial solid waste discharged when the aluminum industry extracts alumina. It is called red mud because it contains a large amount of iron oxide and looks similar to red soil. Due to the difference in ore grade, production method and technical level, about 1.0 to 1.8 tons of red mud are discharged for every ton of alumina produced. In the subsequent extraction and processing of red mud, it needs to be crushed first.
