Description

Technical Field

[0001] This utility model relates to the field of mineral processing technology, and in particular to a drum dryer for quartz sand. Background Technology

[0002] Quartz is a hard, wear-resistant, and chemically stable silicate mineral. Its main component is silicon dioxide, with a relative density of 2.65. It possesses excellent chemical, thermodynamic, and mechanical properties, high refractoriness, and a melting point of approximately 1750°C. The unique physical and chemical properties of natural quartz, including high-temperature resistance, a low coefficient of thermal expansion, high insulation, corrosion resistance, piezoelectric effect, and resonance effect, have led to its increasingly important role in many industries. The processing of natural quartz often employs wet processes such as crushing, grinding, magnetic separation, scrubbing, and flotation, followed by drying.

[0003] Among them, the utility model patent with announcement number CN206399135U discloses a drum dryer for quartz sand. However, the above patent still has certain shortcomings in use. During the drying process of quartz sand, the discharged drying heat cannot be recovered and reused, resulting in a waste of energy resources and making it inconvenient for efficient drying of quartz sand. Therefore, we propose a drum dryer for quartz sand to solve the above problems. Utility Model Content
