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

1. فتحة مدفوعة بنقطة الألم

Managing an iron ore processing operation involves navigating a complex set of efficiency, environmental, and maintenance challenges. هل تعاني:
التوقف غير المخطط له & تلوث: Component failures from nonspecialized wear parts lead to costly stoppages. More critically, standard machinery can introduce restricted hazardous substances (مثل الرصاص, الكادميوم, الزئبق) 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, تآكل هوامش الربح.
أعمال الصيانة المفرطة & جرد قطع الغيار: تغييرات متكررة في الخطوط الملاحية المنتظمة, تحمل الفشل, 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 (بنفايات, يصل), noncompliant equipment can be a source of contamination, risking contract violations and reputational damage.

السؤال المركزي لمديري المصانع هو: how can you achieve reliable throughput while futureproofing your operation against stringent environmental material regulations?

2. نظرة عامة على المنتج

أ RoHS Compliant Iron Ore Crushing Plant is a configured system of primary, ثانوي, and tertiary crushers—such as jaw crushers, الكسارات الدورانية, and cone crushers—along with screens and conveyors, where all wear parts, مواد التشحيم, الأختام, and electrical components are certified free of Restricted Hazardous Substances per Directive 2011/65/EU.

سير العمل التشغيلي:
1. سحق الابتدائي: ذاكرة للقراءة فقط (RunofMine) iron ore is reduced to <200mm by a RoHScompliant jaw or gyratory crusher with certified manganese steel jaws/liners.
2. الفحص & سحق الثانوية: 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. سحق الثلاثي & التحجيم النهائي: لمتطلبات تغذية الحبيبات أو التغذية الملبدة المحددة, additional crushing stages ensure precise particle size distribution using compliant vertical shaft impactors (VSIs) or fine cone crushers.

نطاق التطبيق: Ideal for greenfield projects or retrofits supplying the international steel industry where RoHS/REACH material declarations are required. مناسبة للمغنتيت, الهيماتيت, وخامات التاكونيت.

القيود: 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.
