An Aggregate Crushing Plant is a facility designed to process raw materials like rocks, sand, and gravel into various sizes of aggregate used in construction, padbou, and other infrastructure projects. Here’s a breakdown of its key components and processes:

1. Components of an Aggregate Crushing Plant
- Primêre Breker:
- Breaks down large rocks (bv., kakebeen, gyratory crusher).
- Uitset: Growwe aggregate (bv., 150–50 mm).

- Sekondêre Breker:
- Further reduces material size (bv., kegelbreker, impak breker).
- Uitset: Medium aggregates (bv., 50–20 mm).

- Tersiêre/Kwaternêre Brekers:
- Produces fine aggregates or sand (bv., VSI crusher).
- Uitset: 20–5 mm or smaller.

- Siftingstoerusting:
- Vibrerende skerms skei gebreekte materiaal in verskillende groottes.

- Conveyor Belts:
- Transport material between stages.

- Washing Systems (opsioneel):
- Remove dirt/clay (for high-quality sand/gravel).

- Storage Bins/Silos:
- Hold finished products before shipment.

2. Types of Aggregates Produced
- Growwe aggregate (>4.75 mm): Used in concrete mixes, padbasisse.
- Fyn aggregate (<4.75 mm): Sand for mortar, asfalt.
- Specialty Aggregates: Railway ballast, drainage stones.

3. Prosesvloei
1. Voeding: Raw material dumped into a hopper.
2. Verpletterend: Multi-stage reduction (primary → secondary → tertiary).
3. Sifting: Sized via vibrating screens; oversize recirculated.
4. Wasgoed (indien nodig): Removes impurities.
5. Voorraad opgaar: Sorted aggregates stored for dispatch.

4. Key Considerations
- Material Hardness: Dictates crusher type (bv., jaw for granite, impact for limestone).
- Kapasiteit: Ranges from small portable plants (100 TPH) to large setups (1000+ TPH).
- Omgewingskontroles: Dust suppression, geraashindernisse, waterherwinning.
