# Aggregate Crushing Equipment
Aggregate crushing equipment is used to process raw materials like rock, sand, gravel, or recycled concrete into smaller sizes for construction and industrial applications. Here’s an overview of common types:
## Primary Crushers
– Jaw Crushers: Most common primary crusher; uses compressive force
– Gyratory Crushers: For high-capacity primary crushing of hard materials
## Secondary Crushers
– Cone Crushers: Produces more uniform cubical product
– Impact Crushers: Uses impact force (hammers/blow bars) to crush material
– Horizontal Shaft Impactors (HSI): For softer materials like limestone
– Vertical Shaft Impactors (VSI): For shaping and producing high-quality sand
## Tertiary/Quaternary Crushers
– Fine reduction crushers for producing specific particle sizes
## Mobile Crushing Equipment
– Track-mounted or wheeled units for on-site processing
– Include jaw, cone, and impact crusher configurations
## Screening Equipment
– Vibrating screens to separate crushed material by size
– Scalping screens remove oversized material before crushing
## Considerations When Selecting Equipment:
1. Material characteristics (hardness, abrasiveness, moisture content)
2. Required production capacity
3. Desired end product specifications
4. Mobility requirements (stationary vs. portable)
5. Operational costs and maintenance requirements
Modern aggregate crushing plants often incorporate automated controls and monitoring systems for optimal performance and efficiency.
