100–150 TPH Mobile River Pebble Crushing Plant Project in Indonesia

A Practical Quarry Solution for Stable Aggregate Production

The UNIQUEMAC recently completed the installation and commissioning of a 100–150 TPH mobile river pebble crushing and screening plant in Indonesia. After several months of real operation in a quarry environment, the system has proven to be stable, efficient, and well-suited for processing hard natural stone materials such as river pebbles.

This project was delivered to a local aggregate producer who supplies construction materials for road building, housing development, and small infrastructure projects. The equipment has been running continuously since commissioning, with consistent output and stable performance under demanding site conditions.

Project Background: Increasing Demand for High-Quality Aggregates in Indonesia

In recent years, Indonesia has seen rapid growth in infrastructure development, especially in transportation networks and urban construction. This has significantly increased the demand for high-quality aggregates such as crushed stone and manufactured sand.

However, many local quarries still rely on traditional stationary crushing plants, which often come with limitations such as:

• High civil construction cost before installation
• Long setup and relocation time
• High material transportation cost from quarry to plant
• Limited flexibility when mining locations change

For this reason, the customer in this project began looking for a more flexible and cost-efficient solution that could be deployed directly at the mining site.

Raw Material Characteristics: River Pebble Crushing Challenges

The material processed in this project is natural river pebble, which is widely available in Indonesian quarry zones. While it is a good source of aggregate, it also presents several processing challenges:

• High hardness and strong abrasion resistance
• Irregular shape and size distribution
• High wear impact on crusher components

These characteristics require a crushing system that is not only powerful but also stable under long-term continuous operation.

Solution: 100–150 TPH Mobile Crushing and Screening Plant

To meet these requirements, UNIQUEMAC designed and supplied a wheel-type mobile crushing and screening plant with a capacity of 100–150 tons per hour.

The system integrates multiple processing stages into one mobile unit, including:

• Vibrating feeder for continuous and stable material feeding
• Primary crushing unit for large river pebble reduction
• Secondary impact crusher for shaping and fine crushing
• Vibrating screen for precise material classification

The entire system is mounted on independent mobile chassis, allowing fast relocation between different quarry zones without complex installation work.

Working Process and Final Products

During operation, raw river pebbles are loaded into the feeder and transported into the crushing system. After two-stage crushing and screening, the material is separated into different aggregate sizes.

The final products include:

• 0–5 mm fine sand for concrete mixing
• 5–20 mm aggregate for road base and structural concrete
• 20–31.5 mm coarse aggregate for large-scale construction use

These materials fully meet local construction standards and are widely accepted by downstream concrete batching plants and contractors.

On-Site Performance and Operating Results

After commissioning, the plant has been running steadily under continuous load conditions. The average production capacity remains between 120 and 145 tons per hour, depending on feed material conditions.

One of the most notable advantages reported by the operator is the stability of the system during long production cycles. Even under continuous operation, the equipment maintains consistent output without significant fluctuations.

Maintenance requirements are relatively simple. Daily operation mainly involves routine inspection, lubrication, and wear part monitoring. This reduces downtime and allows operators to focus more on production rather than equipment troubleshooting.

Wear parts such as liners and impact plates have shown good durability, even when processing hard river pebbles with high abrasion resistance.

Customer Feedback from Indonesia Quarry Site

The local operator provided positive feedback after several months of operation. According to their experience, the mobile crushing plant has improved both operational flexibility and production efficiency compared to their previous fixed plant setup.

Key feedback points include:

• Stable and continuous production performance
• Lower material transportation costs due to on-site crushing
• Easier relocation between different mining areas
• Reduced downtime and maintenance interruptions
• Reliable after-sales technical support from UNIQUEMAC

The customer also highlighted that the ability to move the plant directly to the material source has significantly improved overall quarry efficiency.

Advantages of Mobile Crushing Plant in Quarry Operations

Mobile crushing solutions are becoming increasingly popular in modern quarry and mining operations due to their practical advantages:

• No need for large-scale concrete foundation construction
• Fast installation and commissioning time
• Flexible relocation according to mining progress
• Lower overall operational cost
• Suitable for multi-site quarry operations

These benefits make mobile plants especially suitable for regions like Southeast Asia, where quarry locations and material distribution often change over time.

Application Scope

This type of mobile crushing and screening plant is widely used in:

• River pebble and natural stone processing
• Quarry aggregate production
• Road and highway construction projects
• Railway ballast production
• Infrastructure material supply projects

Its flexibility and efficiency make it a practical alternative to traditional stationary crushing lines.

Conclusion

The Indonesia 100–150 TPH mobile river pebble crushing plant project demonstrates how mobile crushing technology can significantly improve quarry productivity while reducing operational complexity.

With stable performance in real working conditions, this project reflects UNIQUEMAC’s experience in delivering practical and reliable crushing solutions for international customers.

For quarry operators looking to improve efficiency and reduce production costs, mobile crushing plants offer a proven and scalable solution.
