Chile 120-150tph River Stone Crushing Line

Chile 120-150tph River Stone Crushing Line: A Model of Efficiency and Sustainability

In the heart of South America, Chile’s mining and construction sectors have long been pivotal to its economic growth. To meet the rising demand for high-quality aggregates, a state-of-the-art river stone crushing line was recently commissioned, designed to process 120-150 tons per hour (tph) of raw material. This project exemplifies how advanced engineering, environmental stewardship, and operational efficiency can converge to deliver exceptional results in resource processing.

Project Overview
The crushing line, located in a resource-rich region of central Chile, was established to transform locally sourced river stone into premium-grade aggregates for infrastructure development and commercial construction. River stone, characterized by its hardness, abrasiveness, and variable grain size, posed unique challenges that required a tailored approach to crushing and screening. The primary objectives included:
– Achieving a consistent output of 120-150tph.
– Minimizing operational costs through energy-efficient equipment.
– Reducing environmental impact with dust suppression and noise control systems.

Technical Challenges & Solutions
1. Material Characteristics
River stone’s high silica content and irregular shapes demanded robust equipment capable of handling wear-resistant processing. To address this, the project incorporated:
– Jaw Crusher (Primary Crushing): A heavy-duty jaw crusher with a deep crushing chamber ensured efficient reduction of large-sized stones (≤750mm) into manageable fragments.
– Cone Crusher (Secondary Crushing): A hydraulic cone crusher optimized particle shape and improved yield by applying interparticle crushing principles.

2. Environmental Compliance
Chile’s stringent environmental regulations necessitated innovative mitigation strategies:
– Closed-loop water spray systems minimized dust emissions at transfer points.
– Soundproof enclosures reduced noise levels to below 85dB, aligning with local standards.

3. Adaptability to Moisture Content
Seasonal variations in river stone moisture were mitigated through:
– Vibrating screens equipped with self-cleaning rubber balls to prevent clogging.
– Adjustable crusher settings to maintain throughput during wet conditions.

Equipment Configuration
The crushing line’s success hinged on a meticulously planned layout and equipment selection:
