A Basalt Crushing and Screening Plant is an industrial facility designed to process volcanic basalt rock into various sizes for construction and industrial applications. Basalt, known for its high compressive strength, abrasion resistance, and low water absorption, is widely used in infrastructure projects. This plant produces aggregates, sand, and powders tailored to specific needs.

    Operational Process

    1. Raw Material Extraction and Feeding:

      • Basalt rocks are extracted from quarries via blasting or excavators.

      • Large blocks (1-2 meters) are transported to the feed hopper for crushing.

    2. Crushing Stages:

      • Primary Crushing:

        • Jaw Crushers (compression) or Impact Crushers (high-speed impacts) reduce rocks to 100-300 mm.

      • Secondary Crushing:

        • Cone Crushers or Horizontal Shaft Impactors (HSI) further crush fragments to 20-50 mm.

      • Tertiary Crushing (Optional):

        • Vertical Shaft Impactors (VSI) produce fine aggregates (3-15 mm) for specialized uses.

    3. Screening and Classification:

      • Vibrating Screens: Separate materials into sizes (e.g., 0-5 mm sand, 10-20 mm gravel).

      • Washing Units: Remove impurities like clay through scrubbing.

    4. Material Handling:

      • Belt Conveyors: Transport materials between stages.

      • Stockpiles: Store categorized products for dispatch.

    5. Automation:

      • PLC systems monitor production efficiency and equipment health.

      • Emergency stops and dust suppression systems ensure safety.

    Applications:

    • Construction and Infrastructure:

      • High-strength concrete aggregates.

      • Asphalt mixes for durable road surfaces.

      • Railway ballast for vibration absorption.

    • Road Construction:

      • Base and sub-base layers.

      • Highway surfacing.
