Cameroon’s growing construction sector demands high-quality sand and aggregates. A specialized marble grinding and sand-making production line can transform raw marble into premium-grade sand and crushed stone for concrete, roads, and landscaping. Below is a streamlined solution for such projects.
1. Primary Jaw Crusher
– Model: PE600×900
– Capacity: 50–160 t/h
– Feed Size: ≤500mm
– Output: 75–200mm
2. Secondary Cone Crusher (for finer crushing)
– Model: HPT300
– Capacity: 120–250 t/h
– Adjustable Output: 10–30mm
3. Marble Grinding Mill (for powder/sand)
– Model: MTW175
– Fineness: 74–44μm (adjustable)
4. VSI Sand Maker (final shaping)
– Model: VSI1140
– Capacity: 200–380 t/h
– Output Shape Index: ≤3% needle content

Q1: What’s the marble-to-sand yield ratio?
*A:* Typically 1:0.6–0.8 (varies by hardness).
Q2: How to control dust pollution?
*A:* Use pulse dust collectors (+99% efficiency) and water spray systems.
Q3: Lifespan of wear parts?
*A:* Jaw plates last ~6 months; VSI rotor tips ~3 months (depends
