1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

You have secured a major contract for a gold processing circuit, but your current supply chain is fragmented across three continents. Lead times for a single ball mill shell are pushing 14 tháng, and your assembly plant floor is idle 40% of the time waiting for matching components. Meanwhile, every day of downtime on a 2,000 tpd CIL plant costs you approximately $120,000 trong sản xuất bị mất.

Are you managing multiple vendors for crushers, màn hình, nhà máy, and leach tanks, only to find that flange tolerances don’t align during final assembly? Are your engineering contractors spending 30% of their budget on field modifications rather than commissioning? The core challenge is not just sourcing equipment—it is sourcing a coordinated, pretested assembly package that meets your minimum order requirements without forcing you to overstock capital.

2. TỔNG QUAN SẢN PHẨM

Của chúng tôi Gold Mining Equipment Assembly Plant là một mô-đun, preengineered production line designed to fabricate, preassemble, and test critical gold recovery components—from primary jaw crushers to carboninleach (CIL) tank agitators—under a single roof with a defined minimum order threshold.

Quy trình hoạt động:
1. Lượng vật liệu & Chế tạo: Raw steel plate (AR400/500) and structural beams are cut via CNC plasma and formed to ISO 2768m tolerances.
2. SubAssembly Station: Crusher frames, mill trunnions, and screen decks are prefitted with hydraulic tensioning systems.
3. PreCommissioning Test Bay: Each assembly undergoes a 4hour run test at 110% rated load to verify bearing temperatures (<65°C) và mức độ rung (<2.5 mm/s).
4. Modular Packing & Gửi đi: Components are crated in ISO containersized modules, reducing onsite installation time by 40%.

Phạm vi ứng dụng: Suitable for greenfield projects (500–5,000 tpd) and brownfield expansions. Hạn chế: Not designed for artisanalscale (<50 tpd) hoạt động; requires a minimum 2,500 sqm assembly floor.

8. Câu hỏi thường gặp

Q: What is the minimum order quantity for a gold processing assembly line?
MỘT: The minimum order is one complete processing line rated for 500 tpd, including primary crusher, màn hình rung, máy nghiền bi, and four CIL tanks. Smaller orders are not economically viable due to fixed setup costs for CNC programming and test bay configuration.

Q: Can your assembly plant produce equipment for nongold applications?
MỘT: Đúng, the same fabrication and test infrastructure can produce components for copper, bạc, and base metal processing. Tuy nhiên, the minimum order and pricing are based on gold circuit specifications. A requote is required for nongold applications.

Q: How does the 6week lead time compare to custom fabrication?
MỘT: Standardized modules allow us to maintain a buffer of precut steel and premachined flanges. Custom fabrication typically requires 16–20 weeks because each component is engineered from scratch. Our 6week lead time applies to orders placed within our quarterly production schedule.

Q: What happens if a component fails during the precommissioning test?
MỘT: The test bay is equipped with diagnostic tools to identify root cause within 2 giờ. If a defect is found, the component is replaced from our inventory within 24 giờ. The failed unit is reworked and retested before being added to the next order. This process ensures no defective equipment ships to your site.

Q: Do you provide foundation drawings and installation manuals?
MỘT: Đúng, each order includes a complete engineering package: foundation loading diagrams (in CAD format), bolt torque specifications, alignment procedures, and a 200page installation manual. We also offer a 3day virtual training session for your installation team.

Q: Can the minimum order be split across multiple shipments?
MỘT: Đúng, we offer phased delivery options. Ví dụ, you can order the crushing circuit first (lô hàng 1), followed by the grinding circuit (lô hàng 2, 8 weeks later). Each shipment still meets the minimum order value of $2.8M. This allows you to match equipment delivery with site readiness.

Q: What is the warranty coverage on pretested assemblies?
MỘT: Standard warranty covers defects in materials and workmanship for 12 months from commissioning or 18 months from shipment, whichever occurs first. This includes all CNCmachined interfaces, hệ thống thủy lực, and drive trains. Consumable items (lót, màn hình, thắt lưng) are excluded.
