The main component of silica sand or quartz sand is SiO2, and the content of less than 98.5% is called silica sand. Silica sand processing plant mainly includes crushing, washing, grading, magnetic separation, flotation and other processes to remove fine or trace impurities in silica sand.

  1. Crushing: Large silica sand is initially crushed using a jaw crusher or cone crusher to reduce the size of the material.

  2. Screening: The crushed silica sand is graded using a vibrating screen to separate materials of different particle sizes.

  3. Washing: Impurities such as clay and organic matter are removed from the silica sand using a sand washer or spiral sand washer.

  4. Drying: The moisture content of the silica sand is reduced using a rotary dryer to meet the requirements of subsequent processing or storage.

  Silica sand products, especially high-purity silica sand, require thorough dehydration. Drying is typically used to reduce the moisture content to approximately 0.5% to meet production specifications. Sand dryers are widely used in industries such as building materials and chemicals, and are designed to process large quantities of material. A rotating drum dries the wet sand through heat exchange with hot air. Jiutian's sand dryer features a rational design that ensures optimal material and airflow for optimal drying. Compared to traditional sand drying equipment, it offers high thermal efficiency, low investment costs, and superior environmental performance.
