Description

Technical Field

[0001] The present invention relates to the technical field of quartz sand processing, and specifically relates to a vibrating classification device for quartz sand particles. Background Art

[0002] Quartz sand is quartz particles obtained by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. At the same time, quartz sand is an important industrial mineral raw material, not a chemical dangerous good, and is widely used in industries such as glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, and filter media. Since quartz sand particles of different particle sizes require different times during processing and melting, before melting processing, it is necessary to classify and screen the quartz sand particles. Existing quartz sand classification and screening devices usually have multiple sets of vibrating screens arranged in a hierarchical manner, with a high cost, poor screening effect, and the materials after screening cannot be quickly taken out, making operation and use inconvenient.
