Abstract

The invention belongs to a production method using microwaves to melt aluminum silicate minerals and microwave equipment. The production method has the advantages that the aluminum silicate minerals are calcined, crushed, powdered and pelletized and then molten in the microwave equipment, the problem that traditional aluminum silicate mineral melting is high in energy consumption and potential safety hazard is solved, production efficiency is increased, and energy consumption is lowered by more than 30%. The microwave equipment has the advantages that based on the production method, the feed inlet of the microwave equipment is adjusted, a microwave damping spiral feeder is used, and efficient feeding is achieved while radiation harm, caused by microwave leakage, to human bodies is prevented by microwave damping; the material of a furnace discharge outlet is regulated to guarantee the service life of the microwave equipment and the continuity of aluminum silicate mineral microwave melting.

Description

technical field [0001] The invention belongs to the technical field of material processing, and in particular relates to a production method of microwave melting aluminum silicate minerals and microwave equipment. Background technique [0002] Aluminum silicate minerals refer to oxide mixtures containing alumina and silicon oxide, which often exist in various forms in nature, such as: andalusite, which belongs to the orthorhombic crystal system; kyanite, which belongs to the triclinic system; silicon wire Stone belongs to the orthorhombic crystal system. In addition, there are kaolin, bauxite, coal gangue, coke gemstones and so on. [0003] Aluminum silicate minerals have low thermal conductivity, excellent thermal and chemical stability. However, aluminum silicate minerals have a high melting point and are difficult to melt. The existing aluminum silicate minerals are usually melted by electric hoist or resistance furnace, and the melting method has low efficiency and hig...
