Kaolin, a versatile clay mineral, requires specialized crushing and grinding equipment to produce high-quality sand and aggregates for construction, ceramics, and other industries. Below is a breakdown of the key equipment and processes involved in a kaolin crushing and sand-making production line.
1. Jaw Crusher (Primary Crushing)
– Model: PE-400×600
– Feed Size: ≤340mm
– Capacity: 16–64 t/h
– Power: 30 kW
2. Impact Crusher (Secondary Crushing)
– Model: PF-1210
– Feed Size: ≤350mm
– Capacity: 50–80 t/h
– Power: 110 kW
3. Sand Maker (Vertical Shaft Impact Crusher)
– Model: VSI-7611
– Feed Size: ≤50mm
– Capacity: 60–180 t/h
– Power: 110–220 kW
4. Vibrating Screen
– Model: 3YK-2160
– Screen Layers: 3
– Capacity: 50–500 t/h
1. Primary crushing with a jaw crusher to reduce kaolin to ≤100mm.
2. Secondary crushing using an impact crusher for finer particles (≤30mm).
3. Sand making via VSI crusher to produce 0–5mm high-quality sand.
4. Screening to separate aggregates into different sizes (e.g., 0–5mm, 5–10mm).
Q1: What is the moisture tolerance for kaolin crushing?
A: Ideal moisture content should be below 10% to prevent clogging.
Q2: Can the line produce both sand and aggregates?
A: Yes, adjustable crushers and screens allow multi-size output.

Q3: What’s the lifespan of wear parts in VSI crushers?
A: Typically 200–400 hours, depending on kaolin hardness.

A project in Vietnam utilized the above setup to process 200 t/h of kaolin, producing sand for
