Highly robust primary crushing equipment and precision components optimized for processing Seychelles granite, basalt, and marine aggregates.
The Republic of Seychelles, an archipelago of 115 islands in the western Indian Ocean, is globally renowned for its pristine natural reserves and high-end tourism. However, behind this tranquil exterior lies a constant demand for infrastructure development, coastal rehabilitation, and land reclamation. These initiatives require massive volumes of aggregates, basalt rocks, and structural components.
Given the remote location of Seychelles, importing raw aggregates is cost-prohibitive. Consequently, the local crushing and quarrying industry, focused on islands such as Mahé, Praslin, and La Digue, is of paramount strategic importance. High-quality crushing systems are needed to process the island's high-hardness granite reserves into usable sand and aggregate without disrupting the fragile ecosystem.
Traditional mining and quarrying practices face strict regulatory control under the Seychelles Ministry of Agriculture, Climate Change and Environment. Industry players must opt for machinery with low noise profiles, minimal vibration, and advanced dust-suppression features.
Modern cone crushers, including hydraulic models, are preferred over outdated crushing setups because their high efficiency lowers the cost per ton and reduces the environmental footprint. Implementing closed-loop water treatment in washed-sand plants prevents muddy effluent from contaminating local coral ecosystems, which is critical for Seychelles' sustainable development goals.

The granitic islands of Seychelles consist of hard, high-quartz microgranite. This material is highly abrasive (with a high Bond Work Index), making primary crushing difficult. Standard jaw crushers can suffer rapid tooth-plate wear, leading to frequent downtime.
To address this challenge, our CZC Jaw Crusher and PEW European Jaw Crusher are designed with optimized nip angles and heavy-duty, high-manganese cast jaw plates. These features allow operators to achieve a high reduction ratio while extending the service life of critical wear parts.
Seychelles quarries operate close to the ocean, exposing equipment to salt-laden, humid sea air. Standard structural steels can rust quickly in these conditions, leading to structural failures in vibrating screens and crusher frame welds.
Hanhai implements strict metallurgical control on all structural castings. We use micro-alloyed cast steel with enhanced trace copper and chromium content to improve atmospheric corrosion resistance. Additionally, all components receive multi-layer polyurethane marine-grade coatings to protect them from environmental damage.
