1. فتحة مدفوعة بنقطة الألم

Are you managing a midtolarge scale aggregate operation and facing persistent bottlenecks that erode profitability? لمديري المصانع والمقاولين الهندسيين, ال 250300 TPH capacity range is critical, yet often problematic. وتشمل التحديات المشتركة:
إنتاجية غير متناسقة: Feed material variability causing output to fluctuate below the 250 TPH target, failing to meet project batching schedules and leading to costly penalties.
High PerTon Operating Costs: Premature wear on crusher liners and screens, combined with inefficient power distribution across multiple units, driving maintenance and energy expenses higher than budgeted.
التوقف المفرط للصيانة: Poorly coordinated plant layouts and components with staggered service intervals result in unplanned stops, reducing overall plant availability below 92%.
Product Quality Inflexibility: Inability to quickly adjust crusher settings and screen configurations to switch between railway ballast, قاعدة الطريق, and concrete aggregates without halting production.

How do you consolidate a reliable 300 TPH output from varied feed material while controlling operational costs and maximizing plant uptime? The solution lies in a holistically engineered stationary crushing and screening plant designed specifically for this duty cycle.

2. نظرة عامة على المنتج

إن محطة تكسير الحجارة OEM 250300tph كاملة, stationary crushing circuit engineered for highvolume production of certified aggregates from hard rock formations like granite, البازلت, and river stone. It is designed as a primarytotertiary processing system for contractors and mining operations requiring consistent, highyield output.

سير العمل التشغيلي:
1. التخفيض الأولي: Dumpfed material is crushed by a robust primary jaw crusher, reducing large feed (≤750mm) to a manageable size for secondary processing.
2. ثانوي & سحق الثلاثي: Material is conveyed to a cone crusher(ق) لمزيد من تقليل الحجم, producing intermediate aggregates. A tertiary impact crusher may be integrated for shaping applications.
3. تصنيف الحجم: Crushed material is routed through multideck vibrating screens to precisely separate product sizes (على سبيل المثال, 05مم, 510مم, 1020مم, 2031.5مم).
4. إعادة التدوير & التخزين: Oversize material is automatically returned via closedcircuit conveyors for recrushing. Onspec product is conveyed to designated stockpiles.

نطاق التطبيق & القيود:
نِطَاق: Ideal for large infrastructure projects (الطرق السريعة, السكك الحديدية), commercial concrete batching plants supply, and permanent quarry sites.
القيود: This is a stationary plant requiring foundational work and grid power connection. It is not suitable for frequent relocation. Optimal feed material should have an abrasion index (منظمة العفو الدولية) below .20 for expected wear part life.

6\. سيناريوهات التطبيق

Highway Base Course Production

Challenge A national contractor needed a guaranteed minimum of 280 TPH of Class II road base material (31.5مم) from abrasive basalt rock but faced constant liner wear issues causing unpredictable downtime.
Solution Implementation of the OEM plant featuring the heavyduty feeder/grizzly section paired with highefficiency cone crushers configured specifically for abrasive rock.
Results Wear part intervals increased by over two operating shifts between changes while maintaining consistent throughput of >290 TPH over an eightmonth project duration.
