Project & Client Needs
Sanyuantang focus on high-capacity, high-precision screening systems for mineral processing. This quartz sand screening production line is our flagship turnkey case for bulk solid separation.
Our client operates a quartz sand plant and required a reliable quartz sand classifier with a total throughput of 400 tons per hour. High-purity quartz sand demands strict multi-grade particle separation. The finished material must be classified into five sizes: 8mesh, 20mesh, 40mesh, 70mesh and 120mesh.
Traditional screening equipment failed to meet their production targets. It suffered from fast mesh abrasion, uneven material distribution, unstable grading precision and limited handling capacity. After evaluating multiple screening technologies, the client chose Sanyuantang gyratory screeners as the core equipment for their new line.
Custom Solution
Our engineering team ran material tests, process simulation and site layout planning to lock in the final design:
- Core Equipment: 16 sets Sanyuantang gyratory screeners
- Single unit output: 25 TPH
- Total capacity: 400 TPH
- Mesh sizes: 8, 20, 40, 70, 120 multi-layer screen decks
We arranged all 16 machines in a straight line and mounted them on a heavy-duty customized steel platform in the client’s workshop, as shown in the site photo. This linear layout optimizes feeding and finished-product conveying paths, saves floor space, simplifies pipework and simplifies routine inspection and maintenance of this high capacity mineral screening machine system.
Why Gyratory Screeners for Quartz Sand?
Sanyuantang gyratory screeners adopt gentle reciprocating gyratory motion, which outperforms linear vibrating screens and rotary sifters when processing hard, abrasive quartz sand.
- Less screen wear: Soft gyratory movement reduces impact between hard quartz grains and mesh, extending screen service life and cutting replacement costs.
- One-pass multi-grade separation: Multi-layer decks produce 5 particle sizes in one screening step to simplify the whole production flow.
- Stable high throughput: Each Sanyuantang gyratory screen steadily runs at 25TPH, supporting 24h continuous heavy-duty operation.
- Reliable grading accuracy: Consistent particle size for high-purity quartz sand used in glass, casting, industrial filler and ceramic industries.
Implementation & Results
We delivered the full project scope: equipment manufacturing, factory pre-assembly inspection, shipment guidance, on-site installation guidance and final commissioning.
After startup, the entire quartz sand screening production line runs smoothly and hits the 400TPH design target. The client confirmed all quartz sand fractions fully meet the required mesh specifications. This high capacity mineral screening machine system has a low failure rate, minimal downtime and lower maintenance workload compared with their old screening equipment.
