8. Câu hỏi thường gặp

What is the typical lead time from agreement to first aggregate production?
For sites with all permits secured and basic infrastructure present, first production can commence within 6090 days following mobilization of client's crushing plant.

How do you ensure consistent aggregate gradation across different blast sequences?
Our sites employ a controlled blasting plan managed by certified engineers, coupled with a processing circuit that includes postcrush screening decks. This allows for precise recirculation and blending to maintain NISspecified gradation bands.

Are these quarry sites suitable for setting up a permanent stationary crushing plant?
Đúng. The sites are surveyed and prepared with stable platforms suitable for permanent plant foundations. Utility access points are established at designated locations.

What commercial model provides the best cost certainty for a largescale infrastructure project?
An exclusive offtake agreement typically offers the highest degree of cost certainty, locking in price per tonnage grade for the project duration while the operator manages all extraction risks.

Is technical training provided for our personnel on sitespecific geology and safety protocols?
Đúng. A mandatory site induction covering geology, safety zones, emergency procedures, and material flow is provided by our operations team prior to any client activity commencement
