In the Philippines' booming construction industry, the demand for high-quality building aggregates is increasing. We have successfully delivered and are operating a 120-ton-per-hour crushing production line specifically designed for processing river pebbles (Mohs hardness 4-5).
This production line, with its precise equipment selection, streamlined process flow, and superior product quality, has become a model for similar projects in the region.

I. Core Project Requirements and Technical Highlights
• Raw Material Characteristics: River pebbles, maximum feed size ≤ 600mm, medium to high Mohs hardness (4-5), strong abrasion resistance.
• Capacity Requirements: Stable processing capacity of 120 tons/hour.
• Finished Product Applications: Primarily used for high-quality building aggregates, requiring reasonable particle size distribution, excellent particle shape, and controllable powder content.
• Technical Highlights: The production line features a compact design and employs a closed-loop circulation process of "two-stage crushing + high-efficiency screening + clean sand washing," emphasizing high efficiency, stability, and environmental friendliness.
II. Core Equipment Configuration and Function Analysis
The stable and efficient operation of the entire production line benefits from the precise coordination of the following key equipment:
1. Feeding Stage: ZSW9638 Vibrating Feeder
◦ Responsible for uniformly and continuously feeding river pebbles from the raw material hopper into the primary crusher, avoiding material blockage and providing a stable guarantee for subsequent crushing.
2. Primary Crushing Stage: PE600×900 Jaw Crusher
◦ Core Function: As the "first crusher" of the production line, its powerful crushing force can easily crush large river pebbles under 600mm to medium particle size.
◦ Advantages: Simple and robust structure, large crushing ratio, reliable operation, convenient maintenance, effectively reducing initial investment and long-term operating costs.
3. Medium and Fine Crushing Stage: CS110 Cone Crusher
◦ Core Function: Receives material from the jaw crusher and performs medium and fine crushing. Its layered crushing principle is particularly suitable for crushing medium to high hardness materials such as river pebbles.
◦ Advantages: High crushing efficiency, uniform product particle size, good particle shape (high cubic content), and flexible adjustment of discharge particle size, perfectly meeting the stringent requirements for particle shape in high-quality aggregates.
4. Screening and Grading Stage: 3YK1860 Vibrating Screen
◦ Core Function: Precisely screens the crushed mixture.
◦ Advantages: Three-layer screen design, adjustable amplitude, high screening efficiency. It can quickly and clearly grade materials according to different specifications (e.g., 0-5mm, 5-10mm, 10-20mm, etc.). Unqualified materials are returned to the cone crusher for further crushing (closed-loop circulation), ensuring the final product qualification rate.
5. Cleaning Stage: XSD Series Sand Washing Machine
◦ Core Function: Cleans the fine particles (especially manufactured sand) after screening, removing surface-adhered mud, impurities, etc.
◦ Advantages: High washing efficiency, low water consumption, significantly improving the cleanliness of aggregate products, meeting the market demand for high-end building materials.
III. Brief Description of Production Process
River pebble raw material → ZSW9638 feeder (uniform feeding) → PE600×900 jaw crusher (coarse crushing) → CS110 cone crusher (medium and fine crushing) → 3YK1860 vibrating screen (screening and grading) → (qualified finished product) → XSD sand washing machine (washing and impurity removal) → clean and high-quality building aggregate.
IV. Project Achievements Summary
Since its commissioning, this production line has operated smoothly and fully achieved its design goals:
• Stable output: Consistently stable at over 120 tons/hour.
• High-quality finished product: Excellent aggregate particle shape, reasonable gradation, high cleanliness, and strong market competitiveness.
• Low operating costs: Reasonable equipment selection, long wear-resistant parts life, low failure rate, and simple maintenance.
This river pebble production line, based on the core configuration of a PE600x900 jaw crusher and a CS110 cone crusher, is a successful solution proven in practice. It provides a reliable technical and equipment blueprint for investing in high-hardness stone processing in the Philippines and similar Southeast Asian regions.
