The cost of an overland coal conveyor depends on factors like length, capacity, terrain, and material handling requirements. A typical system ranges from $1 million to $20 million, with longer distances (>5 km) requiring higher investments due to structural supports, drive systems, and dust control measures.
A complete sand and aggregate production line includes:
– Primary Crusher: Jaw crusher (e.g., 900×1200 mm feed opening, 220–450 t/h capacity)
– Secondary Crusher: Cone crusher (e.g., HP300, 200–350 t/h)
– Tertiary Crusher: Vertical shaft impactor (VSI) for shaping (e.g., 50–300 t/h)
– Screening: Multi-deck vibratory screens (e.g., 3YK3070, 100–400 t/h)
– Conveyors: Belt width 650–1400 mm, speed 1.0–2.5 m/s

Q: What’s the lifespan of a coal conveyor?
A: Typically 15–20 years with proper maintenance.
Q: How to reduce dust in sand production?
A: Use water spray systems or enclosed conveyors.
Q: What’s the ideal moisture content for sand screening?
A: Below 5% to prevent clogging.
A project in Australia deployed a 3 km overland conveyor (1,200 mm belt width, 1,500 t/h capacity
