A modern rock quarry operation in Alamance County requires efficient crushing and sand-making equipment to produce high-quality aggregates. Below is a streamlined production line solution for granite/basalt processing:
1. Primary Jaw Crusher
– Model: JC98
– Feed Size: ≤650mm
– Capacity: 150-300 TPH
– Power: 110 kW
2. Secondary Cone Crusher
– Model: HPT300
– Max Input: 240mm
– Output: 19-38mm (adjustable)
– Capacity: 120-250 TPH
3. Tertiary Impact Crusher (Sand Maker)
– Model: VSI6X1150
– Feed Size: ≤50mm
– Sand Yield: 70-140 TPH
– Fineness Modulus: 2.6-3.0
4. Vibrating Screen
– Deck Layers: 3-4
– Screening Efficiency: ≥90%
Raw stone → Primary crushing (coarse aggregates) → Secondary crushing (mid-size aggregates) → Sand making (mechanized sand) → Screening → Finished products (0-5mm, 5-10mm, 10-20mm, etc.).
Q1: What’s the lifespan of wear parts?
*A:* Jaw plates last ~6 months; cone crusher liners ~8 months under normal use.
Q2: Dust control measures?
*A:* Wet spraying systems + bag filters reduce dust to <20mg/m³.
A quarry in Alamance County adopted this line in 2023, achieving:
– Output: 450 TPH aggregates + 120 TPH M-sand.
– ROI period: <18 months.
