ڪنڪريٽ-استعمال ريل ٺاهڻ جو سامان
Concrete-use sand making equipment is essential for producing high-quality artificial sand (manufactured sand or M-sand) as a substitute for natural sand in construction. Here are the key types of equipment and considerations:
1. Types of Sand Making Equipment
# (1) عمودي شافٽ اثر کولہو (VSI Crusher)
- اصول: Uses high-speed rotor and anvils to crush rocks into cubical sand particles.
- فائدا:
- سٺي معيار جي پيداوار, angular sand ideal for concrete.
- Low fines generation (adjustable gradation).
- Energy-efficient compared to other crushers.
- درخواستون: Best for hard rocks (گرينائيٽ, بيسالٽ).
# (2) High-Efficiency Fine Crusher
- Suitable for softer materials (چونا پٿر, ڊولومائٽ).
- Produces uniform particle size with lower energy consumption.
# (3) هيمر کولہو
- Cost-effective but generates more flaky particles (less ideal for high-strength concrete).
# (4) Roll Crusher
- Used for secondary crushing to refine sand gradation.
2. معاون سامان
- وائبريٽنگ فيڊر: Ensures steady material supply.
- Jaw/Cone Crusher: Primary crushing before sand making.
- Sand Washer: Removes excess dust and impurities (important for concrete quality).
- چمڪندڙ اسڪرين: Classifies sand into different sizes (0-5mm for concrete).
3. Key Considerations for Concrete Sand Production
- ذرات جي شڪل: Cubical grains enhance workability and strength.
- درجي بندي: Must meet ASTM C33 or local standards (مثال, 0–5mm wit
15% ڏنڊ).
- Moisture Control: Wet processing reduces dust but requires drying for ready-mix concrete.
4. Popular Manufacturers
- , , (High-end VSI crushers)
- Liming ڳري صنعت, ايس بي ايم (Cost-effective solutions)
5. ماحولياتي & Cost Factors
- Dust control systems (bag filters, water spray).
- Energy consumption vs. output optimization.
