1. Overview of silica sand production line
Silica sand (quartz sand) is an important raw material for glass, casting, photovoltaic, electronics and other industries. Its purity and particle size directly affect product quality. The silica sand production line processes raw ore into high-quality silica sand that meets the standards of different industries through crushing, sorting, purification, drying and other processes.
1.1 Core advantages:
✔ Efficient sorting：using magnetic separation, flotation, gravity separation and other technologies to improve SiO₂ purity (up to 99.9%).
✔ Energy saving and environmental protection：low energy consumption design, equipped with dust recovery system, in line with environmental protection standards.
✔ Customized solution：matching the best process according to ore characteristics (hardness, impurity content).
2. Silica sand production line process flow
2.1 Crushing stage
• Coarse crushing: jaw crusher handles large pieces of raw ore (≤50mm).
• Fine crushing: Cone crusher/impact crusherfurther refines (≤10mm).
2.2 Sorting and purification
• Magnetic separation: remove iron impurities (applicable to photovoltaic grade high-purity silica sand).
• Flotation: separate associated minerals such as feldspar and mica.
• Gravity separation: spiral classifier/shaking table classification to ensure uniform particle size.
2.3 Dehydration and drying
• Dehydration screen + dryer, control moisture ≤0.5%, meet packaging requirements.
