Papua New Guinea 250tph Limestone Mobile Crushing Plant: A Model of Efficiency and Adaptability

The mining and construction industries are increasingly prioritizing mobility, sustainability, and operational flexibility. A prime example of this trend is the 250tph Limestone Mobile Crushing Plant deployed in Papua New Guinea (PNG), a project that exemplifies how modern crushing technology can overcome geographical challenges while delivering high productivity. This article explores the design, implementation, and value proposition of this innovative system.

Project Overview
Located in PNG’s rugged highlands, the limestone quarry required a crushing solution capable of processing 250 metric tons per hour (tph) to meet growing demand for construction aggregates. Traditional stationary plants were deemed unsuitable due to limited infrastructure, remote site conditions, and the need for rapid relocation as extraction zones shifted. The mobile crushing plant emerged as the optimal choice, combining portability with industrial-grade performance.

Challenges Addressed
1. Remote Terrain: PNG’s mountainous landscape posed logistical hurdles for equipment transportation and setup.
2. Variable Feed Conditions: Fluctuations in limestone hardness (ranging from medium to high abrasiveness) demanded adaptable processing.
3. Infrastructure Constraints: Limited grid power availability necessitated diesel-electric hybrid systems.
4. Environmental Compliance: Strict dust and noise regulations required advanced mitigation technologies.

Solution: Customized Mobile Crushing Configuration
The plant integrates modular components designed for swift assembly and disassembly. Core equipment includes:
– Primary Crusher: Heavy-duty jaw crusher with hydraulic adjustment to handle varying feed sizes (0–700mm).
– Secondary Crusher: Multi-cylinder hydraulic cone crusher for precise shaping of 0–40mm aggregate.

– Mobile Screening System: Triple-deck vibrating screens with interchangeable meshes for grading 0–5mm, 5–20mm, and 20–40mm products.
– Intelligent Control System: IoT-enabled monitoring for real-time optimization of production parameters.

Mobility Features
– Track-mounted chassis enabling autonomous movement at 1–2 km/h.
– Foldable conveyors reducing setup time by 30% compared to conventional systems.
– Containerized power unit with Tier 4 Final diesel engine meeting emission standards.

Operational Advantages

1. Rapid Deployment: Full commissioning achieved in <72 hours versus weeks for stationary plants.
2. Fuel Efficiency
