خط تكسير حجر نهر شيلي 250tph: نموذج للكفاءة والاستدامة

In the rugged terrains of Chile, where natural resources abound and industrial demands grow, the development of a 250-ton-per-hour (tph) river stone crushing line stands as a testament to modern engineering and sustainable resource utilization. This project, tailored to process river stones into high-quality aggregates, not only addresses Chile's infrastructure needs but also exemplifies innovative solutions in mineral processing. Below, we explore the technical highlights, operational strategies, and environmental considerations that define this successful endeavor.

نظرة عامة على المشروع
The 250tph river stone crushing line was commissioned to meet the rising demand for construction aggregates in Chile's booming infrastructure sector. Located near a riverbed rich in alluvial deposits, the site was selected for its abundant raw material supply and strategic proximity to key transportation networks. The primary objective was to produce 0-5mm, 5-20مم, and 20-40mm aggregates for use in concrete production, طبقات قاعدة الطريق, and other civil engineering applications.

التحديات & الحلول
1. خصائص المواد:
River stones are naturally rounded and vary in hardness due to prolonged water erosion. This posed challenges for consistent crushing efficiency.
حل: A multi-stage crushing process was adopted, combining jaw crushers for primary crushing and cone crushers for secondary refinement. This ensured optimal particle shape and minimized wear on equipment.

2. High Altitude & Harsh Climate:
The site’s elevation (زيادة 2,500 مترا فوق مستوى سطح البحر) affected equipment performance due to reduced oxygen levels.
حل: Customized machinery with enhanced air intake systems and cooling mechanisms was deployed to maintain operational stability.

3. الامتثال البيئي:
Strict Chilean regulations required minimal dust emissions and water usage.
حل: Dry-process dust suppression systems were integrated alongside enclosed conveyor belts. Water recycling technologies were implemented for washing processes, reducing freshwater consumption by 40%.

تكوين المعدات
The crushing line features a carefully curated selection of machinery:
- سحق الابتدائي: A heavy-duty jaw crusher (PE-1200×1500) handles large-sized river stones with a feed size of up to 1,000mm.
- سحق الثانوية: Two hydraulic cone crushers (HPT300) ensure precise shaping and grading of aggregates.

- الفحص & غسل: Multi-layer vibrating screens classify materials into specified sizes,
