4YK1548 Vibrating Screen for River Pebble Crushing Plant in Philippines

Complete Sand Washing & Aggregate Production Solution by UNIQUEMAC

🟧 Project Overview

UNIQUEMAC recently successfully delivered a fully integrated river pebble crushing, screening, and sand washing production line in Cagayan de Oro, Philippines. This project was designed for high-efficiency processing of natural river pebbles into standardized construction aggregates and high-quality manufactured sand.

At the core of this production line is the 4YK1548 four-deck circular vibrating screen, which plays a critical role in material classification and final product quality control. The equipment ensures that crushed river stone materials are accurately separated into multiple size fractions, significantly improving the efficiency of downstream sand washing and aggregate utilization.

This project represents a typical modern aggregate production solution in Southeast Asia, where demand for infrastructure materials such as concrete aggregates, road base materials, and manufactured sand continues to grow rapidly.

🟧 Project Background: Increasing Demand for High-Quality Aggregates in the Philippines

Cagayan de Oro is one of the important infrastructure development regions in the Philippines, with abundant natural river pebble resources distributed along local river systems. These raw materials are widely used in construction projects such as highways, bridges, commercial buildings, and housing developments.

However, raw river pebbles cannot be directly used in construction applications. They must undergo multiple stages of processing, including crushing, screening, and washing, to meet engineering standards. The local customer therefore required a complete production system capable of transforming raw stones into stable, graded, and clean aggregates.

The key technical requirements included:

• Stable processing of high-moisture river pebble materials
• Multi-grade aggregate output (coarse, medium, fine)
• Efficient removal of soil, clay, and impurities
• Continuous 24-hour production capability
• Compliance with concrete and highway aggregate standards

After evaluating multiple international suppliers, the customer finally selected UNIQUEMAC due to its proven experience in designing complete crushing and screening plants for Southeast Asian conditions, particularly in high-humidity and high-silt river material environments.

🟧 Customized Crushing, Screening & Washing Solution

To meet the customer’s production requirements, UNIQUEMAC designed a complete integrated system rather than supplying a single machine. The entire production line was optimized based on raw material characteristics, expected output capacity, and final product specifications.

The complete system includes the following major sections:

🔹 Crushing Section

Raw river stones are first processed through a primary crushing system (jaw crusher or equivalent), followed by secondary crushing using an impact crusher. This stage reduces large stones into smaller, uniform particles suitable for screening.

🔹 Screening Section (Core System)

The crushed materials are then transported to the 4YK1548 circular vibrating screen, which performs multi-layer separation. This is the most critical stage of the entire production line, as it determines the final grading quality of aggregates.

🔹 Sand Washing Section

Fine materials are further processed through a sand washing machine to remove excess clay, dust, and organic impurities. This ensures the final manufactured sand meets strict construction-grade cleanliness standards.

🔹 Material Handling System

A series of belt conveyors ensure smooth and continuous transfer of materials between each processing stage, minimizing downtime and maintaining production stability.

🔹 Water Cleaning & Dust Control System

A customized water flushing system is integrated into the screening and washing stages to improve efficiency in handling river pebble materials with high mud content.

Overall, the system is designed as a continuous, fully automated aggregate production line, ensuring high output stability and low operational cost.

🟧 Core Equipment in Focus: 4YK1548 Vibrating Screen

The 4YK1548 vibrating screen is the heart of this project and plays a decisive role in determining product quality and plant efficiency.

This model is a four-deck circular vibrating screen, specifically engineered for medium-to-large scale aggregate production plants.

🔧 Structural Design Advantages

The equipment adopts a reinforced heavy-duty screen box structure, which significantly enhances its resistance to vibration stress during long-term operation. This is especially important when processing river pebble materials, which are typically hard, abrasive, and mixed with fine soil particles.

The screen mesh system is designed with wear-resistant materials, allowing extended service life even under continuous high-load operation. This reduces maintenance frequency and improves overall plant availability.

⚙️ Working Principle & Performance

During operation, the vibrating motor generates a stable excitation force that drives the screen body into a controlled circular motion. Materials are evenly distributed across the four screening layers, allowing simultaneous separation into multiple size categories.

This multi-layer design enables:

• Efficient coarse aggregate separation
• Precise medium-size classification
• Fine sand grading in a single pass

Compared with traditional single-layer screens, the 4YK1548 significantly improves processing efficiency while reducing equipment footprint.

💡 Integrated Water Washing Function

A key advantage in this project is the integration of a water flushing system. This helps remove fine clay and impurities attached to river pebbles during screening. As a result, the final aggregate is cleaner, more uniform, and more suitable for high-grade concrete production.

🟧 Project Performance After Commissioning

After installation and commissioning, the production line entered stable operation quickly and demonstrated strong performance under real working conditions.

The system achieved:

• Stable 24-hour continuous operation without major interruptions
• High-efficiency processing of river pebble raw materials
• Consistent output of multi-grade aggregates
• Noticeable improvement in manufactured sand cleanliness
• Reduced manual intervention and maintenance workload

The combination of crushing, screening, and washing processes ensures that the final products fully meet local construction material standards for highways and commercial infrastructure projects.

🟧 Customer Feedback

The Philippine customer expressed strong satisfaction with both the equipment performance and the overall plant design.

They noted that the vibrating screen operates with excellent stability even under continuous high-load conditions, and the entire production line maintains smooth material flow without blockage or excessive downtime.

“The vibrating screen performs extremely well in river pebble processing. The whole plant runs smoothly with very low failure rate. UNIQUEMAC has proven to be a reliable long-term partner for our business.”

🟧 Industry Applications

This type of integrated crushing and screening solution is widely applicable in modern aggregate production industries, especially in regions with abundant natural river stone resources.

Typical applications include:

• River pebble crushing and sand production plants
• Highway and railway construction material supply
• Concrete batching plant aggregate supply systems
• Large-scale infrastructure development projects

As demand for high-quality manufactured sand continues to increase globally, such integrated systems are becoming the standard solution in many emerging markets.

🟧 Why UNIQUEMAC Solutions Stand Out

UNIQUEMAC focuses on delivering turnkey crushing and screening solutions rather than single equipment sales. This approach ensures that every production line is optimized for real working conditions rather than theoretical performance.

Key advantages include:

• Customized plant design based on raw material characteristics
• Proven experience in Southeast Asia mining environments
• Stable long-term equipment performance under heavy load conditions
• Integrated engineering support from design to commissioning
• Continuous after-sales service and technical optimization

This project in the Philippines is one of many successful installations demonstrating UNIQUEMAC’s engineering capability in aggregate production systems.
