Case study of 170 tph andesite crushing line in Mindanao Philippines

Project background and the client's challenge

Mindanao, the second‑largest island in the Philippines, is rich in andesite deposits, particularly in the Davao, Cotabato, and Surigao regions. These high‑quality volcanic rocks are ideal for infrastructure projects, including the Davao City Bypass Road, the Mindanao Railway Project, and various port expansions. A mid‑sized quarry operator based in Davao del Sur approached OCP Mechanical Company in early 2025 with a clear objective: replace their aging, underperforming stationary plant with a modern, high‑capacity line capable of consistently producing 170 tonnes per hour of premium aggregates. The existing setup was plagued by frequent breakdowns, high energy consumption, and inconsistent product gradation—issues that were costing the client both time and money. This case study of 170 tph andesite crushing line in Mindanao Philippines documents how OCP’s tailored solution transformed their operations, delivering reliable output, lower operating costs, and a rapid return on investment.

Equipment selection and customised plant design

After a thorough site assessment and feed material analysis, OCP engineers designed a three‑stage crushing and screening circuit specifically for the client’s andesite (Mohs hardness 6‑7, silica content ~55%). The line comprises a ZSW vibrating grizzly feeder with adjustable bars, a PE900×1200 jaw crusher for primary reduction (setting CSS at 150 mm), a secondary GP300 cone crusher with fine cavity, a tertiary HST250 cone crusher with extra‑fine cavity, and a 3YK2470 triple‑deck vibrating screen producing four products: 0‑5 mm, 5‑12 mm, 12‑25 mm, and 25‑40 mm. All conveyors were sized to handle 170 tph with belt safety factors of 1.2x, and a centralised PLC control panel was installed to monitor power draw, bearing temperature, and feed rates. The entire line was delivered in four 40‑foot containers from OCP’s manufacturing facility to Davao Port, with on‑site assembly completed in 18 working days under OCP’s remote supervision. This case study of 170 tph andesite crushing line in Mindanao Philippines demonstrates how careful component matching eliminates bottlenecks and maximises uptime.

Operational performance and key metrics

After three months of commercial operation, the new line has consistently exceeded its rated capacity, averaging 175‑178 tph across various feed conditions. Key performance indicators include: a jaw crusher liner life exceeding 1,100 hours (compared with 600 hours on the previous setup), cone liners lasting 800‑900 hours due to optimised CSS settings, and screen panels achieving 1,200 hours before rotation. Energy consumption dropped by 22%—from 6.8 kWh/tonne to 5.3 kWh/tonne—thanks to the high‑efficiency motors and variable‑frequency drives on all major equipment. Product quality has been validated by independent laboratory testing, showing 96% compliance with DPWH Class A aggregate standards. Plant availability stands at 92%, a significant improvement from the previous 78% uptime. The client reports that the payback period for the capital investment is projected at 18 months, based on reduced energy costs, lower maintenance expenses, and the ability to supply premium‑grade aggregates at higher margins. This case study of 170 tph andesite crushing line in Mindanao Philippines provides tangible evidence that well‑engineered equipment paired with proper operational practices delivers measurable results.

Client feedback and operational adaptations

The quarry operator has praised the user‑friendly control system, which allows settings to be adjusted from a central control room. “We used to spend hours manually adjusting the crusher settings. Now we do it in minutes, without stopping production,” noted the plant manager. The remote monitoring capability has been particularly valuable—OCP’s technical team in China can access the PLC system to perform diagnostics and provide troubleshooting advice without the cost and delay of on‑site visits. The client has also implemented OCP’s recommended maintenance schedule, including daily lubrication checks, weekly belt tension adjustments, and monthly liner thickness measurements. This structured approach has reduced unplanned downtime by 60% compared with the previous operation. While the andesite feed occasionally contains high moisture during Mindanao’s rainy season, the vibrating grizzly feeder’s adjustable bars and the screen’s self‑cleaning polyurethane panels have effectively prevented blocking, maintaining steady 170 tph throughput even in wet conditions. This case study of 170 tph andesite crushing line in Mindanao Philippines underscores that successful outcomes combine quality equipment with disciplined maintenance and operator training.

Key lessons and scalability for Philippine operations

Several insights from this case study are applicable to other quarry projects across the Philippines. First, investing in a well‑matched three‑stage circuit, rather than an oversized two‑stage system, provides greater flexibility in product gradation while reducing recirculating loads and wear on downstream equipment. Second, integrating energy‑efficient motors and frequency drives significantly lowers operating costs, especially in regions where power tariffs are high. Third, robust after‑sales support—including remote diagnostics and accessible spare parts inventory—is essential for maintaining high availability in remote locations. The client has since ordered a second OCP line for a new site in Surigao, demonstrating their confidence in the equipment and the partnership.
