The kaolin delamination bead mill is a specialized grinding equipment designed for refining kaolin particles into ultra-fine powders, widely used in high-quality sand and aggregate production lines. Its core function lies in delaminating kaolin layers through mechanical shear forces, improving particle uniformity for downstream processes like concrete or asphalt mixing.
– Grinding Chamber: Typically 50L–500L capacity
– Bead Size: 0.1–1.0 mm zirconia/silica beads
– Motor Power: 15–160 kW
– Throughput: 0.5–10 TPH (varies with material hardness)
– Fineness: Adjustable output of 2–45 μm
In a typical sand production line, the bead mill follows primary crushers and screens. Kaolin slurry is fed into the mill, where rotating discs agitate beads to break down particles. The refined material enhances binding properties in final products like manufactured sand (M-Sand) or lightweight aggregates.
Q: How does it compare to ball mills?
A: Higher energy efficiency (30% less power) and finer output due to concentrated shear forces.
Q: Maintenance frequency?
A: Bead replacement every 800–1,200 hours; seal inspection monthly.
Q: Suitable for quartz sand?
A: Yes, but wear-resistant linings are recommended for abrasive materials.
A 200 TPH sand plant integrated a 300L bead mill to process kaolin-rich feed. Results:
– Yield Increase: 18% higher M-Sand output
– Quality: Achieved ASTM C33 gradation standards
– Energy Use: Reduced by 22% vs traditional milling
This technology bridges mineral processing and construction material production, optimizing both quality and operational costs.
