Achieving Multi-Size Grading Excellence in South Africa’s Crushed Stone Sector with Huatao
Industry Context: South Africa’s Aggregates Demand
South Africa’s construction industry, driven by infrastructure expansion and urban development, requires precise concrete aggregates to meet SANS 1083 standards. With rising demand for graded materials (0–50mm), operators face pressure to optimize production efficiency while minimizing energy consumption.
Customer Challenge: Complex Size Fractionation
A crushed stone plant in Mpumalanga encountered critical bottlenecks:
5-Size Grading Needs: Existing screens failed to simultaneously produce 0-5mm, 5-10mm, 10-20mm, 20-30mm, and 30-50mm fractions, requiring multiple processing stages.
Capacity Constraints: Manual adjustments and screen clogging limited throughput to 18 tons/hour, delaying project timelines.
Maintenance Downtime: Traditional steel screens required weekly replacements due to abrasion from high-silica granite.
Solution: Huatao Lover LTD’s Custom 5-Decks Fine Screen with Poly Ripple Surface
The plant integrated Huatao Lover LTD’s Screen Machine, featuring:
Interlocking Deck System: Modular panels enabled rapid configuration for multi-size grading without downtime.
Poly Ripple Screen Surface: Wave-patterned polyurethane panels optimized material flow, preventing particle bridging and clogging.
Vibrating Screen Media Synergy: Combined with Urethane Fine Screens for <5mm precision and Self-Cleaning Screens for dust control.
Supporting Workflow:
Crushers: Pre-processed raw granite to 50mm feed size.
Sand Washers: Recycled water and removed fines for eco-compliance.
Results: Redefining Aggregate Production Efficiency
Simultaneous 5-Size Output: Achieved 0-5mm (for mortar), 5-10mm (precast concrete), 10-20mm (structural foundations), 20-30mm (road base), and 30-50mm (drainage) in a single pass.
30-Ton/Hour Sustained Capacity: Operated continuously for 18 months with <2% deviation, doubling project delivery speed.
Zero Unplanned Stoppages: Polyurethane panels resisted abrasion, reducing maintenance costs by 40%.
✓Screen Machine:
Interchangeable Decks: Adapted to varying feed sizes (e.g., switching from road base to mortar production in <30 minutes).
Energy-Efficient Drives: Reduced power consumption by 18% compared to conventional models.
✓ Sustainability Impact: Closed-loop water recycling with sand washers aligned with South Africa’s water scarcity mitigation policies.
