stone ne crusher figuer crusher bijih besi

It seems like you’re asking about stone cone crushers and crushers for iron ore (bijih besi). Below is a detailed explanation of both topics:

—

1. Stone Cone Crusher
A cone crusher is a type of compression crusher used in mining and aggregate industries to crush hard and abrasive materials like granite, basalt, and quartz.

# Key Features:
– Working Principle: Crushes material between a rotating mantle and a concave bowl liner.
– Applications:
– Secondary & tertiary crushing in stone quarries.
– Road construction.
– Mining operations (e.g., iron ore, copper ore).
– Advantages:
– High efficiency & productivity.
– Adjustable discharge size.
– Good particle shape.

# Popular Brands:
– Metso (Nordberg HP Series)
– Sandvik (CH & CS Series)
– Terex (Cedarapids MVP)
– Symons

2. Crusher for Iron Ore (Bijih Besi)
Iron ore (bijih b) is a hard, abrasive material that requires robust crushing equipment.

# Suitable Crushers for Iron Ore:
1. Jaw Crusher (Primary Crushing)
– Handles large feed sizes (~1.5m).
– Good for initial reduction.

2. Cone Crusher (Secondary/Tertiary Crushing)
– Best for medium-hard to hard iron ores.
– Provides finer output than jaw crushers.

3. Gyratory Crusher (Large-Scale Mining)
– Used in high-capacity iron ore mines.

4. Impact Crusher (For Softer Ores)
– Suitable if the ore is less abrasive.

# Considerations When Choosing an Iron Ore Crusher:
– Abrasiveness of the ore → Wear-resistant liners required.
– Moisture content → May cause clogging in cone crushers.
– Desired product size → Determines crushing stages needed.
