1. فتحة مدفوعة بنقطة الألم

Are you managing a highvolume aggregate operation and facing persistent bottlenecks that erode profitability? لمديري المصانع والمقاولين الهندسيين, أ 250300 يعد مصنع تكسير الحجارة tph أحد أصول الإنتاج المهمة, yet common operational challenges can significantly undermine its return on investment. These include unpredictable downtime from component failures under continuous heavy load, inconsistent final product gradation leading to premium product loss, and escalating maintenance costs from abrasive wear. بالإضافة إلى, inefficient power utilization and inflexible configurations that cannot adapt to varying feed materials or product specifications create recurring inefficiencies. How do you ensure your crushing circuit delivers its rated 300 tonperhour capacity consistently, maintains precise product specs with minimal waste, and operates with predictable maintenance costs? The specification of the plant itself is the foundational answer.

2. نظرة عامة على المنتج

This specification outlines a complete, ثابتة CE Marked 250300tph Stone Crushing Plant, designed for highvolume production of aggregates for construction, قاعدة الطريق, وصابورة السكك الحديدية. The plant is engineered as a threestage crushing and screening circuit for processing mediumhard to hard stone such as granite, البازلت, أو الحجر الجيري.

The operational workflow follows a logical, efficient path:
1. سحق الابتدائي: مادة تغذية كبيرة (≥750 ملم) يتم تقليلها بواسطة كسارة الفك الأولية القوية.
2. ثانوي & سحق الثلاثي: The output is conveyed to a cone crusher for further size reduction, ensuring optimal particle shape.
3. الفحص & التخزين: Material is classified via multideck vibrating screens; يتم إعادة تدوير الحجم الكبير, while correctly sized fractions are conveyed to designated stockpiles.

Application scope includes largescale quarry operations, major infrastructure project support sites, وساحات التوريد الإجمالية المخصصة. A key limitation is that this plant configuration is designed as a stationary installation; for frequent relocation, a modular or mobile variant would be more appropriate.
