A mining crushing and screening plant is an industrial facility designed to process large mineral and rock blocks extracted from mines into smaller sizes, classify them, and prepare them for various industrial uses. These plants handle raw materials such as iron ore, copper, gold, coal, basalt, limestone, granite, dolomite, and marble.

They supply essential materials for industries including construction, infrastructure projects, road building, concrete and asphalt production, cement manufacturing, energy, metallurgy, and chemicals. The main objective is to process raw materials efficiently and make them suitable for different industrial applications.

Operation Process of a Mining Crushing and Screening Plant

  1. Extraction and Transportation

    • Raw minerals are extracted from mines using blasting, drilling, or excavation.
    • Large rock fragments are transported to the crushing-screening facility via trucks or conveyor belts.

  2. Primary Crushing

    • Large rock blocks are crushed using jaw crushers or impact crushers into smaller sizes.

  3. Secondary Crushing

    • The crushed material is further refined with cone crushers, hammer crushers, or impact crushers.

  4. Screening Process

    • The processed material is passed through different sieves to classify it by size.

  5. Washing and Purification

    • Some minerals undergo a washing process to remove dust, clay, and organic materials.

  6. Storage and Distribution

    • The classified materials are stored and transported to various industries.
