Impianti dërrmues i agregatit
An Aggregate Crushing Plant is a facility designed to process raw materials like rocks, rërë, and gravel into various sizes of aggregate used in construction, ndërtimin e rrugës, dhe projekte të tjera infrastrukturore. Here’s a breakdown of its key components and processes:
1. Components of an Aggregate Crushing Plant
- Thërrmuesi kryesor:
- Breaks down large rocks (p.sh., nofulla nofulla, gyratory crusher).
- Prodhimi: Agregatët e trashë (p.sh., 150–50 mm).
- Thërrmues sekondar:
- Further reduces material size (p.sh., polic kon, polic me ndikim).
- Prodhimi: Medium aggregates (p.sh., 50–20 mm).
- Tertiary/Quaternary Crushers:
- Produces fine aggregates or sand (p.sh., VSI crusher).
- Prodhimi: 20–5 mm or smaller.
- Pajisjet e skanimit:
- Vibrating screens separate crushed material into different sizes.
- Conveyor Belts:
- Transport material between stages.
- Washing Systems (opsionale):
- Remove dirt/clay (for high-quality sand/gravel).
- Storage Bins/Silos:
- Hold finished products before shipment.
2. Types of Aggregates Produced
- Agregatet e trashë (>4.75 mm): Used in concrete mixes, bazat rrugore.
- Agregatet fine (<4.75 mm): Sand for mortar, asfalt.
- Specialty Aggregates: Railway ballast, drainage stones.
3. Process Flow
1. Të ushqyerit: Raw material dumped into a hopper.
2. Thërrmues: Multi-stage reduction (primary → secondary → tertiary).
3. Shqyrtimi: Sized via vibrating screens; oversize recirculated.
4. Larje (if needed): Removes impurities.
5. Grumbullimi i rezervave: Sorted aggregates stored for dispatch.
4. Key Considerations
- Material Hardness: Dictates crusher type (p.sh., jaw for granite, impact for limestone).
- Kapaciteti: Ranges from small portable plants (100 TPH) to large setups (1000+ TPH).
- Environmental Controls: Dust suppression, barrierat e zhurmës, water recycling.
