From Raw Material to Final Product: Crushing and Screening Process
The working principle of crushing and screening plants is based on the synchronous operation of a series of machines to gradually reduce and classify the material:
- Supply: Large-sized raw materials coming from the quarries, Feeders It is fed in a controlled manner to the primary crusher, which is the first stage of the facility.
- Primary Crushing: Generally Jaw Crushers In this stage, where it is used, huge rocks are broken into smaller and more manageable pieces.
- Secondary/Tertiary Crushing: Material coming out of the primary crusher, Impact Crushers or Cone Crushers It is sent to secondary and tertiary crushers such as these and brought closer to the desired final product size.
- Screening and Classification: Crushed material has different folds and mesh openings Vibrating Screens The Screens separate the material into different size fractions (e.g. 0-5 mm sand, 5-12 mm, 12-22 mm aggregate, etc.) by vibrating movement.
- Washing (Optional): If the material contains undesirable substances such as clay, soil, Washers (screw or bucket) is used to clean and product quality is increased.
- Stocking: Classified and/or washed final products, Belt Conveyors transported to separate storage areas.
Application Areas and Advantages
Crushing and screening plants are indispensable for many sectors that form the basis of modern life:
- Construction and Infrastructure: It supplies aggregates (sand, gravel, crushed stone) in all sizes required for concrete and asphalt production.
- Mining: It is used to separate precious metal ores (gold, copper, iron, etc.) from rock and prepare them for enrichment processes.
- Recycle: It produces reusable aggregate by recycling construction and demolition waste (C&D waste) and contributes to environmental sustainability.
- Industrial Raw Material: It brings the raw materials required for industries such as glass, ceramics, cement and lime to the desired sizes.
