Iron ore BHP
How is iron ore mined? From pit to port, our iron ore undergoes a series of processes before export. First, we explore the geology of the region to find the best iron ore prospects for our operations. Once the ideal site has been chosen, the ore is drilled and blasted. It is then transported to the primary crusher for processing.The primary crusher is located in the quarry and consists of a McLanahan 48″x72′ Shale King Crusher rated at 1,000 TPH (Tons Per Hour).

To study and optimize the gyratory crusher performance, taking the process of crushing iron ore by the gyratory crusher as the specific analysis object in this paper. First, the discrete element method (DEM) analysis model of the iron ore based on the bonded-particle model (BPM) is established. On this basis, the impacts of the mantle Mine haul-truck capacity is an important factor at primary crusher installations, because it is cost-effective to integrate truck cycle time at the crusher station with mine/shovel operations. If a primary crusher dump pocket is undersized and unable to handle the mine’s trucks, then operators must slowly meter the ore into the receiving hopper.Crushing Plant Design and Layout Considerations 911 Metallurgist

primary crushing process for iron ore mines
In a typical iron ore mine, the primary crushing process involves the use of a large gyratory crusher, which can crush large rocks and ores into smaller pieces. The crushed material is then transported to the surface using conveyor belts, where it is further processed and refined.Among the comminution and grinding equipment, HPGR is increasingly utilized as tertiary crusher or primary mill because of low energy consumption, low operating costs, and improving the energyProcessing of Magnetite Iron Ores–Comparing Grinding Options
