China clay (kaolin) requires specialized crushing equipment due to its soft and abrasive nature. A primary crusher like a jaw crusher or hammer crusher is typically used to break down raw clay into smaller particles (<50mm) for further processing in sand/aggregate production lines.
1. Primary Crusher:
– Model: PE-400×600 Jaw Crusher
– Feed Size: ≤340mm
– Output: 16-60t/h
– Motor Power: 30kW
2. Secondary Crusher: Cone crusher or impact crusher for finer crushing (≤20mm).
3. Sand Maker: VSI crusher produces 0-5mm clay sand for construction use.
4. Screening & Washing: Vibrating screen and log washer remove impurities.

Q1: What’s the best primary crusher for sticky clay?
A: Hammer crushers with anti-clogging designs are preferred for high-moisture clay.
Q2: Can China clay be used directly as construction sand?
A: No, it requires washing and grading to meet ASTM/C33 standards.
A Jiangxi-based project processed 200t/h China clay using:
1. PE-600×900 jaw crusher (primary) → PYD1200 cone crusher (secondary) → VSI1140 sand maker → Screens & classifiers. Final output: 0-5mm sand (120t/h) and 5-20mm aggregate (
