A Hard Stone Crushing Plant is designed to process tough, Bahan kasar seperti granit, basalt, kuarza, and other high-hardness rocks. These plants are widely used in mining, pembinaan, and aggregate industries to produce high-quality crushed stone for roads, konkrit, dan aplikasi lain.

Key Components of a Hard Stone Crushing Plant
1. Penghancur utama
- Kursus rahang: Ideal for initial crushing of large, hard stones (mis., granit, basalt).
- Crusher Gyratory: Suitable for very large feed sizes in mining operations.

2. Penghancur sekunder
- Penghancur kon: Best for medium-to-hard stones (mis., kerikil sungai, kuarza).
- Kesan penghancur: Used for softer but still hard materials (mis., limestone with high abrasiveness).

3. Penghancur Tertiary/Quaternary (Fine Crushing & Membentuk)
- Vertical Shaft Impact (Semua orang) Penghancur: Produces well-shaped sand and fine aggregates.
- High-Pressure Grinding Roll (Hpgr): Used for ultra-fine crushing in some advanced plants.

4. Peralatan pemeriksaan
- Skrin bergetar berasingan bahan dihancurkan ke dalam saiz yang berbeza (mis., 0-5mm, 5-20mm, 20-40mm).

5. Penghantar & Pengumpan
- Belt conveyors transport material between stages.
- Vibrating feeders ensure steady material flow.

6. Sistem penindasan habuk
- Water spray or mist systems reduce dust emissions.

7. Sistem kawalan
- PLC-based automation ensures efficient operation.

Typical Hard Stone Crushing Process
1. Letupan & Memuatkan (if from a quarry) → Primary crushing → Secondary crushing → Screening → Tertiary shaping → Final screening → Stockpiling.

2. If producing sand: Additional VSI crushers + sand washing machines may be included.

Considerations for Hard Stone Crushing
- Pakai rintangan: Use high-manganese steel or ceramic liners in crushers to handle abrasiveness.
- Kecekapan tenaga: Cone crushers are more efficient than jaw crushers for secondary crushing.
- Kandungan kelembapan: Wet processing may be needed if the stone contains clay or dirt.
- Keperluan Produk Akhir: Adjust crusher settings based on desired output
