1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Are escalating operational costs and unpredictable downtime eroding your iron ore processing margins? Plant managers and engineering contractors face persistent challenges in primary crushing stages that directly impact downstream efficiency and profitability. Điểm đau phổ biến bao gồm:
Mặc quá mức & Chi phí bảo trì: Abrasive iron ore rapidly degrades crusher liners, leading to frequent shutdowns for replacement, high spare parts expenditure, and lost production.
Unplanned Downtime from Tramp Metal: Hidden scrap metal or uncrushable material in feed causes catastrophic damage to crusher internals, resulting in days of unscheduled downtime and sixfigure repair bills.
Inconsistent Feed Size & Capacity Bottlenecks: Poorly sized feed from the mine or an inefficient primary crusher creates choke points, limiting throughput and preventing the plant from reaching its designed capacity.
Tiêu thụ năng lượng cao trên mỗi tấn: Older crushing technology often operates at low mechanical efficiency, making energy one of the largest variable costs with poor ROI on power spend.
Phát thải bụi & Safety Compliance: Inadequate containment at primary crushing points creates hazardous work environments, triggers regulatory noncompliance risks, and represents valuable product loss.

Is your current primary crushing solution a reliable asset or a constant source of cost and delay? The right engineered Chinese Iron Ore Crushing Plant addresses these challenges directly.

2. TỔNG QUAN SẢN PHẨM

This solution is a heavyduty, stationary primary crushing station engineered specifically for the volumetric reduction of runofmine (rom) quặng sắt. It is centered on a robust gyratory or jaw crusher designed for maximum reliability and throughput in highabrasion applications.

Quy trình hoạt động:
1. ROM iron ore is dumped into a reinforced hopper by haul trucks.
2. A vibrating grizzly feeder (VGFF VGF) removes fine material (100mm) via a bypass chute while evenly feeding oversize material to the primary crusher.
3. The core primary crusher reduces the ore to a nominal product size of 150250mm through compressive force.
4. Crushed material is discharged onto a main conveyor system for transport to secondary crushing or stockpiling.

Phạm vi ứng dụng: Ideal for greenfield mine development or brownfield plant expansion requiring highcapacity (2,000 10,000+ TPH), continuousduty primary reduction of magnetite, hematit, or other ironbearing ores.

Hạn chế: Not suitable for portable or semimobile applications without significant structural modification. Requires stable foundational concrete works and planned feed control for optimal performance.
