Description

Technical Field

[0001] This utility model relates to the field of slag recycling technology, and in particular to a coal chemical solid slag recycling equipment. Background Technology

[0002] Coal chemical solid slag is mainly a solid waste generated during the coal combustion process. The main components of coal slag are inorganic substances such as silicon dioxide, iron oxide, and aluminum oxide, while also containing a certain amount of organic matter, heavy metals and their compounds. Coal slag can be utilized through recycling technology, which generally involves a coal chemical solid slag recycling equipment.
