verview of Gravel Production in Chile

Common Gravel Sources

Chile’s diverse geological landscape provides several natural sources for aggregate production:

Key Geographic Regions for Aggregate Production

Chile’s gravel production aligns closely with the distribution of major economic zones:

Norte Grande (e.g., Antofagasta, Tarapacá)

Driven mainly by mining operations. Large-capacity crushing plants supply aggregates for mine construction and road maintenance.

Central Chile (Santiago, Valparaíso, O’Higgins)

The highest demand due to urban growth, highway development, cement plants, and industrial construction.

Southern Regions (Maule to Los Lagos)

More river stone extraction due to glacial and fluvial formations; used widely in civil works and concrete mixing.

Types of Stone Crushers Suitable for Gravel Production

Jaw Crusher:

Ideal for primary crush of river stone and hard mountain rock. Known for robust design and wide feed range, making it popular in both small and large installations.​

Cone Crusher:

best for secondary and tertiary stages, especially when a precise aggregate size is needed (such as road base or concrete sand). Excels with tough rocks like basalt, offering shape refinement and consistent gradation.​

Impact Crusher:

Efficient for softer stones (river stone, some volcanic rocks) and for producing fine or highly-shaped gravel aggregates with minimal dust and lower wear costs.​

Mobile Crusher:

Combines multiple crushing stages and screening onto one frame, with quick relocation between sites; valuable for projects where the source of material changes or construction zones shift regularly.

Considerations: River Stone vs. Basalt in Chile

Basalt & Andesite (Common in Andes Mountains):

Extremely hard and abrasive → Best processed using Jaw + Cone Crusher combinations.

River Stone (Typical in Central & Southern Chile):

Softer and rounded → Jaw + Impact Crusher or Impact-only lines can reduce costs.

Current Price Ranges for Stone Crushing Equipment in Chile

Example Production Line Configurations

Beginner / Small Quarry (50–100 tph)

A balanced and cost-efficient setup:

• Jaw Crusher → Cone Crusher → Vibrating Screen
• Jaw Crusher reduces large raw stone to manageable size.
• Cone Crusher shapes and refines the aggregate.
• Vibrating Screen sorts stone into final size fractions (e.g., 0–5 mm, 5–20 mm, 20–40 mm).

Ideal For: Local builders, municipal construction, ready-mix concrete suppliers.

Large-Scale Mining Contractor (200–500+ tph)

High-output line for continuous, industrial operation:

• Jaw Crusher → Cone Crusher → Cone Crusher → Screening Plant
• Primary Jaw handles heavy basalt/andesite.
• Dual Cone Crushers provide continuous shaping and consistent grading.
• Screening Plant divides material into multiple commercial sizes.

Ideal For: Copper mine access roads, port expansion, large concrete batch plants, and industrial infrastructure projects.
