Silica sand is a fundamental raw material for glass manufacturing, foundry casting, ceramics, and chemical production. Unlike ordinary construction sand, silica sand requires strict control over particle size (0.15–2mm) and purity (low iron, clay, or organic matter). An 80TPH (tons per hour) silica sand making plant is engineered to meet these demands, turning raw silica ore into high-quality, market-ready silica sand.
1. High Product Value: The end product sells for a significant premium over construction aggregate.
2. Optimal for Specialization: This capacity is ideal for focusing on high-value industrial markets rather than high-volume, low-margin construction sand.
3. Process Control: The scale allows for excellent quality control to meet strict industry specifications (e.g., for glass or foundry use).
4. VSI sand making machine has low energy consumption and high production capacity in the sand making process. Wheel type sand washer and sand recycling machine are to get high quality fine sand.
If the feed material contains lumps or is too coarse, a small Jaw Crusher or Hammer Crusher may be used for initial size reduction. However, for many sand deposits, this stage may be bypassed.
This is the most critical stage for shaping and liberating impurities. A Vertical Shaft Impact (VSI) Crusher is used not just for size reduction, but for its attrition effect.
Function: The "rock-on-rock" crushing action grinds sand grains against each other, effectively scrubbing off iron oxide and other stains from the surface of each grain. This significantly improves purity.
This stage is what defines an industrial sand plant. A High-Efficiency Vibrating Screen is used to precisely separate sand particles by size.
Function: A vibrating screen separates crushed silica rocks into multiple graded sizes (e.g., 0-2mm, 2-5mm) by using high-frequency vibration to move material across layered screens with different gap sizes.
The classified sand is sent to a wheel type sand sasher for a final rinse. This step removes any remaining light impurities and provides a clean, drip-free product. A dewatering screen is then used to achieve a consistent, low-moisture content product ideal for shipping and further processing.
