Aggregate Crushing Plant
An Aggregate Crushing Plant is a facility designed to process raw materials like rocks, سانت, and gravel into various sizes of aggregate used in construction, روڊ جي عمارت, and other infrastructure projects. Here’s a breakdown of its key components and processes:
1. Components of an Aggregate Crushing Plant
- پرائمري کولہو:
- Breaks down large rocks (مثال, جبڙو, gyratory crusher).
- ٻاھر: ٿلهو مجموعو (مثال, 150–50 mm).
- ثانوي کولڻ وارو:
- Further reduces material size (مثال, مخروط کولہو, اثر کولہو).
- ٻاھر: Medium aggregates (مثال, 50–20 mm).
- Tertiary/Quaternary Crushers:
- Produces fine aggregates or sand (مثال, VSI کولہو).
- ٻاھر: 20–5 mm or smaller.
- اسڪريننگ جو سامان:
- Vibrating screens separate crushed material into different sizes.
- Conveyor Belts:
- Transport material between stages.
- ڌوئڻ جو نظام (اختياري):
- Remove dirt/clay (for high-quality sand/gravel).
- Storage Bins/Silos:
- Hold finished products before shipment.
2. Types of Aggregates Produced
- Coarse Aggregates (>4.75 ايم ايم): Used in concrete mixes, روڊ جا بنياد.
- Fine Aggregates (<4.75 ايم ايم): Sand for mortar, اسفالٽ.
- خاص مجموعو: Railway ballast, drainage stones.
3. عمل جي وهڪري
1. کارائڻ: Raw material dumped into a hopper.
2. ڪِرڻ: Multi-stage reduction (primary → secondary → tertiary).
3. اسڪريننگ: Sized via vibrating screens; oversize recirculated.
4. ڌوئڻ (if needed): Removes impurities.
5. ذخيرو ڪرڻ: Sorted aggregates stored for dispatch.
4. Key Considerations
- Material Hardness: Dictates crusher type (مثال, jaw for granite, impact for limestone).
- ظرف: Ranges from small portable plants (100 ٽي پي ايڇ) to large setups (1000+ ٽي پي ايڇ).
- Environmental Controls: Dust suppression, شور جي رڪاوٽون, water recycling.
