1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Bạn đang quản lý một hoạt động tổng hợp quy mô vừa và lớn và đang đối mặt với những tắc nghẽn dai dẳng làm xói mòn lợi nhuận? Dành cho người quản lý nhà máy và nhà thầu kỹ thuật, nhà máy nghiền đá 250300tph là tài sản sản xuất quan trọng, tuy nhiên những thách thức vận hành chung có thể làm giảm đáng kể lợi tức đầu tư của nó.

Nguồn cấp dữ liệu không nhất quán & Thời gian ngừng hoạt động: Sự biến động về kích thước thức ăn và độ cứng dẫn đến máy nghiền ngừng hoạt động, unplanned downtime for clearing, and reduced average throughput far below the plant’s rated capacity.
Hoạt động cao & Chi phí bảo trì: Premature wear on liners and crusher components due to improper crushing chamber dynamics or inadequate material flow control results in excessive spare parts consumption and labor for changeouts.
Hình dạng sản phẩm kém & Cấp độ: Inefficient crushing stages produce excess flaky or elongated aggregates, reducing the percentage of premium, inspec product and limiting marketability for highvalue applications like concrete and asphalt.
Inefficient Plant Flow & Cường độ lao động: Manual adjustments, poor transfer point design, and lack of integrated process control require constant operator intervention, leading to higher labor costs and variable product quality.

How do you ensure your 250300tph crushing plant delivers consistent, specontarget output while controlling wear costs and maximizing uptime? The solution lies in an engineered supply chain for a complete plant system designed from the ground up for reliability and efficiency.

2. TỔNG QUAN SẢN PHẨM

This product describes a fully engineered supply chain for a stationary 250300 tonperhour (tph) hard rock stone crushing and screening plant. This is a complete circuit solution designed for highvolume production of aggregates for construction, xây dựng đường, và dằn đường sắt.

Quy trình hoạt động:
1. Nghiền sơ cấp: Đá khai thác lớn (lên tới 750mm) được giảm xuống <200mm by a robust primary jaw crusher.
2. Sơ trung & nghiền cấp ba: Material is then processed through a cone crusher (sơ trung) and optionally a further cone or impact crusher (cấp ba) for precise size reduction and improved particle shape.
3. Sàng lọc vật liệu: Multipledeck vibrating screens separate crushed material into precise specification fractions (ví dụ., 05mm, 510mm, 1020mm).
4. Xử lý vật liệu & Dự trữ: A network of belt conveyors with adjustable discharge heights transports sized products to designated stockpiles.
5. Điều khiển & Giám sát: A centralized PLCbased control system allows operators to manage the entire flow from a single station.

Phạm vi ứng dụng: Lý tưởng cho đá granit, đá bazan, đá vôi, và các cốt liệu mài mòn khác. Suitable for large quarry operations dedicated to supplying readymix concrete plants, nhà máy nhựa đường, và các dự án cơ sở hạ tầng lớn.

Hạn chế: This stationary plant solution requires foundational civil works and is designed for longterm operation at a fixed site. For fully mobile requirements on multiple shortduration sites, a mobile crushing plant configuration would be recommended.
