2. نظرة عامة على المنتج

A modern Bulk Iron Ore Crushing Plant is a engineered system centered on a highcapacity primary gyratory or jaw crusher, designed specifically for the initial size reduction of runofmine (ذاكرة للقراءة فقط) خام الحديد. Its purpose is to reliably reduce large, variablesized feed (في كثير من الأحيان يصل إلى 1.5 متر) to a consistent, conveyable product for secondary processing.

سير العمل التشغيلي:
1. ROM Receiving & الفحص المسبق: Dump pockets or feeders direct ROM ore to a grizzly screen, removing subfines to bypass the crusher and reduce unnecessary wear.
2. تخفيض الحجم الأساسي: The core crusher utilizes compressive force to break down the ore between a fixed surface and a moving mantle or jaw.
3. نقل المنتج: Crushed material is discharged onto a heavyduty conveyor system, typically equipped with metal detection and tramp iron removal, for transport to the next processing stage.

نطاق التطبيق: Ideal for largescale mining operations with annual capacities exceeding 5 مليون طن. Designed for continuous, 24/7 operation under highabrasion conditions.

القيود الرئيسية: Not designed for final product sizing; requires secondary and tertiary crushing circuits for fine reduction. Site requires substantial foundational engineering and capital infrastructure.
