Philippines 1000 TPH Limestone Washing & Aggregate Production Line
This project delivers a fully integrated limestone aggregate processing solution designed for high-humidity, clay-rich mining conditions in the Philippines. With a target output of 1,000 tons per hour (TPH), the production line supplies construction-grade crushed stone, pea gravel, and manufactured sand to meet the fast-growing infrastructure demand across Southeast Asia.
Project Scale
Application Scenario Limestone quarries in the Philippines typically face high surface clay content, tropical rainfall-driven moisture, and strict environmental regulations on dust and wastewater discharge. This solution addresses all these challenges within a single integrated plant layout — eliminating the need for multiple contractors.
Core Pain Points Solved
| Pain Point | Our Solution |
|---|---|
| High clay content causing screen blinding | Spiral Sand Washer + Dewatering Screen for full fines removal |
| Wastewater & slurry discharge compliance | Mud Press system for zero-discharge slurry handling |
| High moisture reducing conveying efficiency | Dewatering Screen reduces surface moisture to <12% |
| Multiple product specs required | Multi-deck YAH Vibrating Screen for simultaneous grading |
| Limited land footprint | Compact plant layout within original site boundary |
Solution Highlights
Customized Limestone Wet-Process Crushing & Washing Flow
Raw limestone is fed into a Jaw Crusher for primary reduction, then passed through a Box Crusher for secondary fine crushing. Material is classified by YAH1536 Vibrating Screens into four product grades: 10–30mm, 10–20mm, 5–10mm, and 0–5mm fines. The fine fraction enters a Spiral Sand Washer to remove clay and impurities, followed by a Dewatering Screen to reduce surface moisture. Wastewater from the washing circuit is processed by a Mud Press, which separates water for recycling and compresses slurry into dry cakes — achieving a fully closed-loop, zero-discharge operation.

Frequently Asked Questions — Philippines Limestone Aggregate Production Line
Q1: Can this production line handle limestone with high clay and moisture content typical in the Philippines? Yes. The combination of Spiral Sand Washer + Dewatering Screen is specifically engineered for high-clay, high-moisture tropical conditions. The washing circuit removes surface clay and fine particles, while the dewatering screen reduces product moisture to below 12%, ensuring conveyor and stockpile performance even in rainy season.
Q2: How does the mud press system work and does it meet Philippine environmental regulations? The Mud Press (filter press) receives slurry from the sand washing circuit, mechanically dewatering it into dry, stackable cakes with moisture below 35%. The filtered water is recycled back into the washing circuit, achieving a closed-loop system with zero liquid discharge — fully compliant with DENR wastewater standards.
Q3: What are the standard product sizes this line produces? The default configuration produces four grades simultaneously:
