A Marble Crushing and Screening Plant is an industrial facility that mechanically breaks down large marble blocks or fragments into aggregates (sand, gravel, powder) of various sizes and classifies them by particle size. These plants transform raw marble into usable materials for construction, decoration, and industrial processes.

How Does It Work?

  1. Crushing Stages:

    • Primary Crushing: Marble blocks are reduced to 50-150 mm pieces using jaw crushers or impact crushers.

    • Secondary Crushing: Cone crushers or hammer crushers further reduce the material to 10-50 mm.

    • Tertiary Crushing (Optional): Roller crushers may be used to achieve 2-10 mm particles in some plants.

  2. Screening Stage:

    • Vibrating screens or rotary screens sort crushed marble into categories like 0-2 mm (powder), 2-10 mm (fine gravel), 10-30 mm (medium gravel), and 30-50 mm (coarse gravel).

  3. Material Handling:

    • Conveyor belts and silos transport sorted products to storage areas.

Functions:

  • Aggregate Production: Produces marble aggregates for concrete, asphalt, and landscaping projects.

  • Powder and Micronized Products: Generates calcium carbonate (CaCO₃) powder for chemical and paint industries.

  • Waste Recycling: Converts marble quarry waste into economically valuable materials.

Applications:

  • Construction: Terrazzo flooring, decorative concrete, road base materials.

  • Decoration: Sculptures, mosaic designs, garden stones.

  • Agriculture: Marble powder for soil pH adjustment.

  • Industry: Filler material in plastics, paper, and cosmetics.
