Description

Technical Field

[0001] The utility model relates to the technical field of integrated equipment, in particular to an extrusion and pelletizing integrated equipment for manufacturing magnesium-containing slag pellets. Background Art

[0002] At present, in the magnesium smelting industry, the global demand for magnesium and magnesium alloys is gradually increasing. As a major magnesium producer, China usually uses the Pidgeon process to smelt magnesium. The Pidgeon process refers to a method of adding materials to a reduction tank and reducing calcined dolomite to metallic magnesium using a ferrosilicon reducing agent in a reduction furnace heated outside the tank. However, a large amount of magnesium slag will be produced during the Pidgeon process. Magnesium slag is a large amount of secondary solid waste, which will pollute the atmosphere, water bodies, soil, etc., and easily affect the health of residents. The current treatment method for magnesium slag is usually to pile it up around the plant or backfill the mine. The above methods have a low comprehensive utilization rate for magnesium slag, poor compatibility with polymers, and greater heavy metal hazards;

[0003] In order to solve the problem of low comprehensive utilization rate of magnesium-containing slag, the prior art proposes a magnesium slag incremental filling technology, which can improve the utilization rate of magnesium slag by filling polyolefin. After filling, it needs to be extruded through an extruder and pelletized through a pelletizer to obtain pellets of suitable size. However, when extruding and pelletizing the magnesium slag, it is necessary to first extrude it through an extruder and then cut it through a pelletizer. The extruder and the pelletizer are separate equipment, which occupy a large space, and the extrusion and pelletizing efficiency of the magnesium slag is low. Utility Model Content
