ROHS Compliant Iron Ore Crushing Plant | Engineered for Sustainable, HighYield Mineral Processing

1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Managing an iron ore processing operation involves navigating a complex set of efficiency, environmental, and maintenance challenges. Bạn đang trải nghiệm:
Thời gian ngừng hoạt động ngoài kế hoạch & Sự ô nhiễm: Component failures from nonspecialized wear parts lead to costly stoppages. More critically, standard machinery can introduce restricted hazardous substances (như chì, cadimi, thủy ngân) into your material stream, jeopardizing product purity and RoHS compliance for downstream steelmakers.
Inefficient Throughput & High Energy Cost: Inconsistent feed size reduction creates bottlenecks, forcing secondary and tertiary crushers to work harder. This directly increases power consumption per ton of processed ore, làm xói mòn tỷ suất lợi nhuận.
Lao động bảo trì quá mức & Kho phụ tùng: Thay đổi lớp lót thường xuyên, hỏng ổ trục, and unplanned repairs demand significant technician hours and require a large inventory of spare parts, tying up capital and increasing total operational cost.
Environmental Compliance Risk: As global supply chains mandate stricter material declarations (RoHS, VỚI TỚI), noncompliant equipment can be a source of contamination, risking contract violations and reputational damage.

Câu hỏi trọng tâm đối với các nhà quản lý nhà máy là: how can you achieve reliable throughput while futureproofing your operation against stringent environmental material regulations?

2. TỔNG QUAN SẢN PHẨM

MỘT RoHS Compliant Iron Ore Crushing Plant is a configured system of primary, sơ trung, và máy nghiền bậc ba—chẳng hạn như máy nghiền hàm, máy nghiền hồi chuyển, and cone crushers—along with screens and conveyors, where all wear parts, chất bôi trơn, con dấu, and electrical components are certified free of Restricted Hazardous Substances per Directive 2011/65/EU.

Quy trình hoạt động:

2. Sàng lọc & Nghiền thứ cấp: Oversize material is routed to a cone crusher for further reduction. All screen meshes and crusher liners in the contact path are manufactured from compliant alloys.
3. nghiền cấp ba & Định cỡ cuối cùng: Đối với các yêu cầu về thức ăn viên hoặc thức ăn thiêu kết cụ thể, additional crushing stages ensure precise particle size distribution using compliant vertical shaft impactors (VSI) or fine cone crushers.

Phạm vi ứng dụng: Ideal for greenfield projects or retrofits supplying the international steel industry where RoHS/REACH material declarations are required. Suitable for magnetite, hematit, và quặng taconit.

Hạn chế: Maximum feed size and throughput are determined by the specific plant configuration. Not designed for processing materials outside typical iron ore abrasion indices without specific liner customization.
