1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Bạn đang quản lý hoạt động sản xuất 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 vốn quan trọng, yet its performance directly dictates your bottom line. Common operational challenges include:
Thông lượng không nhất quán: Fluctuations in feed material hardness or size leading to an average output below the 280tph design target, causing project delays and missed delivery schedules.
Thời gian ngừng hoạt động quá mức: Frequent mechanical failures in key components or lengthy changeover times for maintenance, resulting in hundreds of lost production hours annually.
Chi phí hoạt động cao: Uncontrolled wear part consumption, inefficient power draw per ton of processed material, and the labor intensity of routine monitoring.
Sự thay đổi về chất lượng sản phẩm: Inability to consistently meet multiple spec products (ví dụ., 05mm, 1020mm, 2040mm) simultaneously due to inflexible or poorly calibrated crushing stages.
Hạn chế về khả năng mở rộng: A fixed plant configuration that cannot adapt to changing project demands or feed materials without significant capital reinvestment.

Câu hỏi trung tâm là: how do you select a 250300tph crushing plant that transforms these cost centers into reliable, predictable production?

2. TỔNG QUAN SẢN PHẨM

Sản phẩm này là một sản phẩm hoàn chỉnh, văn phòng phẩm 250300 TPH Hard Stone Crushing and Screening Plant. It is engineered for continuous, highvolume production of aggregates for large infrastructure projects, commercial concrete batching, and road base construction.

Quy trình hoạt động:
1. Nghiền sơ cấp: Nguyên liệu thức ăn lớn (≤750mm) được giảm xuống 200mm bằng máy nghiền hàm sơ cấp mạnh mẽ.
2. Sơ trung & nghiền cấp ba: Material is conveyed to a cone crusher circuit for further reduction, producing precisely shaped intermediates.
3. Sàng lọc & Phân loại: Multipledeck vibrating screens separate crushed material into specified finished product sizes.
4. Tuần hoàn: Oversize material is automatically returned via conveyors to the appropriate crusher for reprocessing (closedcircuit design).
5. Dự trữ: Finished aggregates are conveyed to designated stockpiles for loadout.

Phạm vi ứng dụng & Hạn chế:
Phạm vi: Lý tưởng để chế biến đá granite, đá bazan, sỏi sông, and other abrasive materials with compressive strength up to 350MPa. Suited for permanent quarry sites or longduration (3+ year) project bases.
Hạn chế: Not designed as mobile or semimobile equipment; relocation requires disassembly. Maximum feed size and final capacity are contingent on specific material characteristics. Not optimal for processing sticky or highclay content materials without prescreening/scalping modifications.
