150t/h River Pebble Crushing Plant in Curimaná, Peru – High-Efficiency Aggregate Production
Introduction
UNIQUEMAC proudly announces the shipment of a 150t/h river pebble crushing plant to Curimaná, Ucayali Region, Peru, a region characterized by abundant river pebble deposits and tropical rainforest conditions. This plant is carefully engineered for the unique challenges of Amazonian river pebble processing, where high moisture, hard and rounded stones, and abrasive material demand robust equipment and precise workflow. By integrating high-efficiency jaw and cone crushers, advanced vibrating feeders, and multi-deck screening technology, this crushing plant guarantees consistent, high-quality aggregates suitable for concrete, asphalt, and road construction projects along the UC-102 highway. Operators in South America can now rely on a turnkey solution designed for both productivity and durability.
How the Curimaná River Pebble Crushing Plant Works
The plant follows a three-stage crushing process in a closed-loop configuration, which maximizes efficiency, ensures uniform grading, and reduces waste. Each stage is optimized to handle the highly abrasive and moisture-rich Amazonian river pebbles, providing stable and reliable output.
1. Controlled Feeding (GZT0932 Vibrating Feeder)
The first step involves loading raw river pebbles into the GZT0932 vibrating feeder, which regulates the flow to the primary jaw crusher. Unlike conventional feeders, this unit uses high-frequency vibration to remove fine clay and sticky soil, common in river deposits, preventing blockages and uneven feeding. This ensures that large stones enter the crusher at a consistent rate, minimizing stress on the equipment and improving energy efficiency. In addition, the feeder’s reinforced structure allows it to withstand the high moisture and weight of Amazonian pebbles, providing operators with stable, long-term performance even during the rainy season.
2. Primary Coarse Crushing (PE600×900 Jaw Crusher)
Once fed, the pebbles enter the PE600×900 jaw crusher, the heart of the primary crushing stage. This crusher uses compressive force between a fixed and moving jaw plate to reduce large pebbles (100–200mm) into smaller, manageable sizes. The deep crushing chamber ensures even oversized stones are fully crushed, while high-manganese steel plates resist abrasion, prolonging service life. This stage not only reduces the material size but also prepares the pebbles for subsequent fine crushing, ensuring consistent quality output. Operators benefit from reduced downtime and predictable throughput, which is critical for large-scale quarry operations in remote regions like Curimaná.
3. Secondary Fine Crushing & Shaping (PSGB-0917 Symons Cone Crusher)
Crushed material from the jaw crusher is transported to the PSGB-0917 Symons cone crusher for secondary processing. This stage is crucial for shaping the aggregates into uniform, cubical particles, preferred for high-strength concrete and asphalt applications. The cone crusher employs a rotating mantle within a concave bowl, applying continuous compression to hard, abrasive pebbles. Its hydraulic adjustment system allows operators to precisely control product size, maintaining consistency across batches. This stage is particularly effective in producing well-graded aggregates from the rounded, tough river pebbles typical of the Ucayali region.
4. Screening & Classification (3YK1860 Vibrating Screen)
Finally, the crushed material passes through the 3YK1860 three-deck vibrating screen, which separates the aggregates into different sizes: 0–5mm, 5–20mm, and 20–40mm. Oversized material is automatically recirculated back to the cone crusher for re-crushing, creating a closed-loop system that maximizes yield and minimizes waste. The screen’s robust frame and high-efficiency surfaces ensure it handles high-moisture and high-volume material without loss of performance, critical for maintaining throughput and product quality in Amazonian quarries.
Key Advantages of the Curimaná River Pebble Crushing Plant
This plant is optimized for the specific challenges of river pebble processing in South America, offering multiple operational advantages:
- Superior Durability & Wear Resistance: The jaw and cone crushers use high-manganese steel wear parts, while the feeder and screen feature reinforced frames. This design reduces maintenance and downtime, even when processing extremely abrasive and rounded river pebbles.
- High Cubical Aggregate Quality: Unlike impact crushers that can produce flaky material, the combination of jaw and cone crushing produces uniformly cubical aggregates, resulting in stronger concrete and asphalt, meeting the rigorous standards of Peruvian construction projects.
- Adaptable to Variable Feed Sizes & Moisture: Pre-screening in the vibrating feeder removes excess moisture and fine material, preventing clogging and ensuring continuous operation, even during the rainy season (November–April).
- Energy Efficiency & Reduced Operating Costs: By separating coarse and fine crushing stages, the system minimizes unnecessary wear and reduces electricity consumption per ton of aggregate.
- Modular & Expandable Design: The skid-mounted plant can be installed quickly on flat, alluvial terrain and expanded in the future with additional components, such as tertiary crushers or washing units, providing long-term flexibility for growing operations.
Tailored for Curimaná’s Unique Site Conditions
The tropical rainforest climate, flat terrain, and local river pebble characteristics of Curimaná demanded careful engineering:
- Climate Adaptation: Equipment is treated with anti-corrosion coatings to withstand humidity above 80% and annual rainfall up to 2,500mm, ensuring long-term durability.
- Terrain Compatibility: Modular design allows for quick, stable installation on flat alluvial plains, reducing site preparation time while maintaining operational stability.
- Material Suitability: The combination of jaw and cone crushers is specifically selected for hard, rounded river pebbles, producing high-quality aggregates consistently.
Site maps and location coordinates illustrate the optimal plant placement along the Curimaná river basin, enhancing logistics and material sourcing efficiency.
