Kaolin, a key raw material in ceramics and construction, often requires grinding aids to optimize particle size distribution and reduce energy consumption during crushing. In sand and aggregate production lines, specialized equipment ensures high-quality output while minimizing operational costs.
1. Jaw Crusher (Primary Crushing)
– Model: JC-1200
– Feed Size: ≤850mm
– Capacity: 150-300 TPH
– Power: 110 kW
2. Vertical Shaft Impact Crusher (VSI)
– Model: VSI-900
– Max Feed Size: 50mm
– Output: 0-5mm (adjustable)
– Power: 250 kW
3. Ball Mill with Grinding Aid System
– Model: BM-3.2×4.5
– Capacity: 12-15 TPH (kaolin powder)
– Grinding Aid Dosage: 0.05%-0.1% of feed weight

Q1: Why use grinding aids for kaolin?
A1: They reduce particle agglomeration, lower energy use by ~20%, and improve mill throughput.
Q2: How to choose a VSI crusher for kaolin sand?
A2: Prioritize models with adjustable rotor speed (e.g., 1,500-2,800 RPM) to control gradation.
Project: Guangdong Kaolin Sand Plant (2023)
Solution: Deployed JC-1200 + VSI-900 + BM-3.2×4.5 with glycol-based grinding aid. Achieved 95% passing 200 mesh at 14 TPH, reducing power cost by $15/ton compared to conventional milling
