1. فتحة مدفوعة بنقطة الألم

Are you managing a midtolarge scale aggregate production operation and facing persistent bottlenecks that cap profitability? لمديري المصانع والمقاولين الهندسيين, a 250300tph stone crushing plant represents a critical production tier where inefficiencies translate into significant financial impact. وتشمل التحديات المشتركة:
إنتاجية غير متناسقة: Unplanned downtime from feeder to crusher mismatches or conveyor bottlenecks, losing hundreds of tons per shift.
تكاليف تشغيلية عالية: Spiking wear part consumption in secondary/tertiary stages and excessive energy use per ton of finished aggregate.
تباين جودة المنتج: عدم القدرة على تلبية منتجات المواصفات المتعددة باستمرار (على سبيل المثال, 3/4" إجمالي, 1/2" رقائق, الرمال المصنعة) from variable feed material.
Excessive Footprint & وقت الإعداد: Modular plants that require extensive civil works and complex interconnection, delaying commissioning and ROI.

السؤال المركزي هو: how do you achieve reliable 250300tph output with lower costperton, صيانة مبسطة, and the flexibility to adapt to changing project demands?

2. نظرة عامة على المنتج

إن محطة تكسير الحجارة الثابتة بقدرة 250300 طن في الساعة كاملة, engineered solution designed for continuous, إنتاج كميات كبيرة من الركام لقاعدة الطريق, أسمنت, وتطبيقات الأسفلت. تم تكوينه للابتدائي, ثانوي, and tertiary crushing stages to produce precisely graded end products.

سير العمل التشغيلي:
1. التخفيض الأولي: صخرة مقلع كبيرة (ما يصل إلى 750 ملم) is fed into a primary jaw crusher for initial size reduction.
2. سحق الثانوية & الفحص: يتم نقل الإخراج إلى كسارة مخروطية ثانوية. شاشة أساسية تفصل المواد ذات الحجم, routing oversize back for further crushing.
3. التشكيل الثلاثي & التحجيم النهائي: Material requiring additional shaping is processed through a tertiary cone or impact crusher. Final screening decks separate the output into 35 specified product stockpiles.

نطاق التطبيق: Ideal for dedicated aggregate quarries, large infrastructure project support bases, and highdemand commercial concrete operations.
القيود: This plant configuration requires stable, hard rock feed (الجرانيت, البازلت, الحجر الجيري). For very abrasive or highsilica content materials, يوصى باستخدام معادن بطانة محددة. It is not a portable solution and requires planned foundation work.
