machines for iron ore processing plant

Iron ore processing plants require various machines and equipment to efficiently extract, crush, grind, concentrate, and pelletize iron ore. Below is a breakdown of the key machines used in different stages of iron ore processing:

1. Crushing & Screening Equipment
Used to reduce large chunks of raw iron ore into smaller pieces for further processing.
– Primary Crushers: Jaw crushers, gyratory crushers
– Secondary Crushers: Cone crushers, impact crushers
– Tertiary Crushers: High-pressure grinding rolls (HPGR), vertical shaft impactors (VSI)
– Screening Machines: Vibrating screens (linear, circular), trommel screens

2. Grinding Equipment
Used to grind crushed ore into fine particles for beneficiation.
– Ball Mills (wet/dry grinding)
– Rod Mills (coarse grinding)
– SAG Mills (Semi-Autogenous Grinding)
– Vertimills® (energy-efficient fine grinding)

3. Beneficiation Equipment
Separates valuable iron minerals from waste rock (gangue). Common methods include:
# (a) Magnetic Separation
– Low-intensity magnetic separators (LIMS) – for magnetite ores
– High-intensity magnetic separators (HIMS) – for hematite/goethite ores

# (b) Gravity Separation
– Spiral concentrators
– Jigging machines (Batac®, Denver jigs)
– Shaking tables

# (c) Flotationchines
– Column flotation cells
– Mechanical flotation cells

4. Dewatering & Thickening Equipment
Removes water from slurry after beneficiation.
– Thickeners (conventional, high-rate, paste thickeners)
– Filter presses (plate & frame filters, belt filters)
– Vacuum disc filters

5. Pelletizing Equipment *(for pellet plants)*
Converts fine iron ore concentrate into hardened pellets for blast furnaces/DRI plants.
