The Crushing and Sand-Making Industry in South America: A Comprehensive Overview
Industry Background
South America’s construction boom and infrastructure development have driven significant demand for high-quality aggregates, particularly crushed stone and manufactured sand. As urbanization accelerates across countries like Brazil, Chile, Peru, and Colombia, the need for efficient crushing and sand-making solutions has surged. The region’s abundant mineral resources, including granite, basalt, and iron ore, provide raw materials for aggregate production, making second-hand crushing and sand-making machinery a cost-effective option for many local operators.
Core Equipment in Crushing & Sand-Making Lines
1. Primary Crushers:
– Jaw crushers (e.g., PE series) dominate primary crushing stages, handling hard rocks up to 1,500 MPa compressive strength.
– Gyratory crushers are preferred for large-scale mining operations due to higher throughput.
2. Secondary/Tertiary Crushers:
– Cone crushers (hydraulic or spring-type) ensure precise particle size reduction for mid-hardness materials.
– Impact crushers (horizontal/vertical shaft) excel in shaping softer aggregates like limestone.
3. Sand-Making Machines:
– VSI (Vertical Shaft Impact) crushers produce cubical-shaped sand ideal for high-grade concrete.
– High-pressure roller mills generate finer particles with lower energy consumption.
4. Auxiliary Equipment:
– Vibrating screens (multi-deck designs) enable precise grading.
– Sand washers remove impurities from manufactured sand.
Market Dynamics & Applications
Used machinery markets thrive in industrial hubs like São Paulo (Brazil) and Santiago (Chile), where 2015–2020 model years offer 30–50% cost savings versus new units. Popular brands include Outotec refurbished plants and mobile screeners.
Key Considerations When Buying Second-Hand Equipment
1. Wear Parts Inspection: Check rotor/hammer conditions in impact crushers; mantle/concave wear in cone units (>70% remaining life recommended).
2. Production History: Request maintenance logs—prefer sub-10,000 operating hour units from single-owner quarries.
3. Local Support: Verify spare parts availability; / models have wider dealer networks continent-wide.
FAQ Section
Q: What’s the typical output range for a used 200tph VSI sand-making plant?
A: Expect 60–80tph of 0–5mm sand depending on feed material hardness (+15% variance for moist content).
Q: How to mitigate risks when importing refurbished jaw crushers?
A: Partner with inspection agencies like Bureau Veritas for pre-shipment mechanical tests and laser alignment checks.
Q: Can old mobile crushers handle Andesite rock?
A: Yes, but prioritize units with hydraulic adjustment systems (>2017 models) to manage Andesite’s abrasive silica content.
Project Case Study: Limestone-to-Sand Conversion in Colombia
A Medellín-based contractor repurposed a 2018 Hazemag AP-PH 1315 impact crusher (purchased via Ecuadorian auction) into a sand-making line by adding a CVB2060 screen and cyclone classifier—achieving 120tph of ASTM C33-compliant sand at 40% lower CAPEX than new equipment.
Operators should prioritize equipment compatibility assessments—mismatched conveyor speeds or undersized power supplies remain common pitfalls in used plant deployments.
The South American market’s preference for modular designs makes semi-mobile second-hand crushing stages particularly viable, especially where infrastructure limits fixed plant installations.The Crushing and Sand-Making Industry in South America: A Comprehensive Overview
