Chile 120-150tph River Stone Mobile Crushing Line: A Model of Efficiency and Sustainability
The mining and construction industries in Chile have long been pivotal to the nation’s economic growth. With increasing demand for high-quality aggregates in infrastructure projects, innovative solutions are essential to meet production targets while adhering to environmental standards. The 120-150tph River Stone Mobile Crushing Line deployed in Chile exemplifies how modern technology and strategic planning can harmonize productivity, mobility, and sustainability.
Project Overview
This mobile crushing line was designed to process river stone—a challenging material due to its high hardness and silica content—into construction-grade aggregates. Located in a region with rugged terrain and limited infrastructure, the project required equipment capable of operating efficiently under variable conditions while minimizing logistical complexities. The plant’s capacity of 120-150 tons per hour (tph) ensures a steady supply of materials for local road construction and concrete production.
Challenges & Solutions
1. Material Characteristics:
River stone’s abrasiveness and irregular size distribution posed risks of equipment wear and inconsistent output. To address this, the crushing line incorporated a multi-stage screening and crushing system. Primary crushing utilized a heavy-duty jaw crusher to break down large stones, followed by secondary cone crushers for finer shaping. Advanced wear-resistant materials were selected for critical components to extend service life.
2. Mobility & Flexibility:
Traditional fixed crushing plants are impractical in remote or temporary sites. The mobile configuration—featuring tracked crushers and screens—allowed rapid deployment and relocation without costly groundwork. This flexibility proved vital in Chile’s mountainous regions, where site accessibility is often limited.
3. Environmental Compliance:
Dust and noise pollution are common concerns in aggregate production. The system integrated closed-loop dust suppression systems and noise-reduction technologies, ensuring compliance with Chile’s stringent environmental regulations. Additionally, the energy-efficient design reduced fuel consumption by 15–20% compared to conventional setups.
Equipment Configuration
The crushing line’s core components include:
– Primary Crusher: A high-performance jaw crusher for coarse crushing, capable of handling stones up to 600mm in diameter.
– Secondary Crusher: A hydraulic cone crusher for medium/fine crushing, optimizing particle shape and size distribution.
– Vibrating Screens: Multi-layer screens to classify aggregates into 0–5mm, 5–20mm
