Bhutan’s growing infrastructure sector, including road construction, hydropower projects, and urban development, demands a steady supply of high-quality aggregates. River boulders—abundant in Bhutan’s river systems—are a valuable source of durable, natural stone for such projects. A 300 tons per hour (TPH) stone crusher plant tailored for river boulders can efficiently convert these large, irregular stones into usable aggregates.
300 TPH River Boulders Crusher Plant Configuration
A 300 TPH plant for river boulders requires a multi-stage crushing process to handle large feed sizes and produce consistent aggregate grades (e.g., 0–5mm, 5–10mm, 10–20mm, 20–40mm). Below is a typical setup:
1. Primary Crushing: Jaw Crusher
● Equipment: Large jaw crusher (e.g., 900×1200mm) with a feed opening capable of accepting boulders up to 750mm.
● Function: Reduces river boulders from 750mm+ to 150–200mm, preparing them for secondary crushing.
● Advantages: High crushing ratio, robust design to handle hard, irregular materials, and low maintenance.
2. Secondary Crushing: Cone Crusher
● Equipment: Medium to large cone crusher CH400 with a hydraulic adjustment system.
● Function: Further reduces 150–200mm material to 40–60mm, improving aggregate shape (more cubic particles).
● Advantages: Efficient for hard rocks, adjustable discharge settings, and high throughput to match 300 TPH targets.
3. Tertiary Crushing: Impact Crusher or HPC Cone crusher (Optional)
● Equipment: Horizontal Shaft Impact (HSI) crusher for final shaping.
● Function: Converts 40–60mm material into fine aggregates (0–40mm) with superior cubicity, ideal for concrete or asphalt.
● Use Case: Recommended if high-quality, well-graded aggregates are required for critical projects.
4. Screening System
● Equipment: Multi-deck vibrating screens (e.g., 3-deck or 4-deck) with high screening efficiency.
● Function: Separates crushed material into desired size fractions (e.g., 0–5mm, 5–10mm, 10–20mm, 20–40mm). Oversized material is recirculated to secondary/tertiary crushers for reprocessing.
5. Conveying and Storage
● Belt conveyors transport material between crushing and screening stages, with covers to minimize dust.
● Stockpiles or silos store final aggregates, ensuring a steady supply for downstream use.
Key Features for Bhutan’s Conditions
● Dust Suppression: Water spray systems or baghouses to control dust, critical for complying with Bhutan’s strict environmental regulations.
● Mobility Options: Semi-mobile or skid-mounted designs for easy relocation, allowing the plant to follow river boulder deposits.
● Weather Resistance: Enclosed electrical panels and corrosion-resistant components to withstand Bhutan’s humid, mountainous climate.
● Energy Efficiency: Crushers with variable frequency drives (VFDs) to optimize power use, reducing operational costs in remote areas.
Benefits of a 300 TPH Plant
● Meets Local Demand: Supplies 300 tons of aggregates per hour, supporting large-scale projects like hydropower dams or national highways.
● Cost-Effective: Utilizes local river boulders, reducing transportation costs for raw materials.
● Quality Aggregates: Produces consistent, durable aggregates that meet Bhutan’s construction standards (e.g., for concrete strength or road base stability).
