A crushing and screening plant is an industrial facility designed to process natural rocks or stones into aggregates (crushed stone, gravel) of various sizes. These plants play a vital role in mining, construction, and infrastructure projects by producing materials essential for concrete, asphalt, road bases, railway ballast, and more.
How Does It Work?
Crushing Process:
Primary Crushers (Jaw crusher, impact crusher): Reduce large rocks (100-150 cm) to 10-15 cm.
Secondary/Tertiary Crushers (Cone crusher, vertical shaft crusher): Further break down material into smaller sizes (2-5 cm).
Cubical Shaping: Ensures angular edges for better concrete bonding.
Screening Process:
Vibrating Screens: Sort crushed materials into specific sizes (0-5 mm, 5-12 mm, 12-25 mm, etc.).
Washing Systems (Optional): Remove dust, clay, or impurities.
Storage and Transportation:
Aggregates are stored in stockpiles and transported to construction sites via trucks.
Applications:
Concrete and asphalt production,
Road and railway construction,
Landfill and backfill material,
Landscaping.
Key Equipment:
Crushers, screens, conveyor belts, washing plants, generators.
