Crushing and Sand-Making Production Line for Coal Mining Applications

The Indo Wana Bara Mining Coal project requires robust crushing and sand-making equipment to process raw materials efficiently. A tailored production line typically includes jaw crushers, cone crushers, vertical shaft impactors (VSI), vibrating screens, and sand washers.

Core Equipment Specifications

<gt;150-400<gt;<gt;30<gt;

Equipment Model Capacity (t/h) Power (kW)
Jaw Crusher PE-600×900 50-120 75
Cone Crusher PYB-1200 110-168 110
VSI Crusher S8-1145 200-300 250×2
Screening Machine S5X-2460

Key Process Flow Design

Primary crushing reduces coal or overburden to ≤150mm. Secondary crushing refines material to ≤30mm for sand-making. The VSI shapes particles into high-quality aggregates (0-5mm, 5-10mm). Screening ensures precise grading before final washing.

FAQ Highlights

– What’s the optimal moisture content?
Keep below 8% to prevent clogging in VSI chambers.
– How to reduce wear?
Use tungsten carbide-tipped rotors in VSIs for abrasive materials.
– Dust control methods?
Water spray systems + bag filters reduce PM10 emissions by 90%.
