1. فتحة مدفوعة بنقطة الألم

إن إدارة عملية الرمل والحصى تعني التعامل مع الثبات, أوجه القصور المكلفة. هل تواجه هذه التحديات المشتركة?
مادة تغذية غير متناسقة: Fluctuations in feedstock size and moisture content lead to frequent clogging, unplanned downtime for manual clearing, and suboptimal screening efficiency.
ارتفاع تكاليف استبدال قطع الغيار: The abrasive nature of aggregate rapidly degrades screen panels, مكونات محرك الأقراص, والمحامل, resulting in excessive spare parts inventory and labor costs for changes.
فصل الغرامات غير فعال: Inaccurate separation of fines from specification product leads to offspec material, wasted product in settling ponds, and potential revenue loss or customer rejection.
Excessive Vibration & صيانة: Poorly balanced or lowquality vibrating screens transmit destructive forces to support structures and require constant bolt tightening, bearing checks, and foundational repairs.
قيود قابلية التوسع: Fixedscreen systems struggle to adapt to changing market demands for different aggregate specifications, forcing operators to choose between capital expenditure for new units or lost sales opportunities.

السؤال المركزي لمديري المصانع هو: how can you increase throughput of inspec material while directly reducing perton operating costs and maintenance hours? The answer lies in the core of your classification process: the industrial vibrating screen.

2. نظرة عامة على المنتج: HEAVYDUTY VIBRATING SCREEN FOR SAND AND GRAVEL

هذه المعدات ذات قدرة عالية, linear motion vibrating screen engineered specifically for the rigorous demands of sand and gravel mining. It is designed for the dry or wet screening of crushed stone, الحصى, رمل, and recycled concrete aggregates.

سير العمل التشغيلي:
1. مقدمة الأعلاف: Raw, crushed aggregate is conveyed onto the feed box of the vibrating screen, which evenly distributes material across the full width of the top deck.
2. التقسيم الطبقي & الانفصال: A precisely calibrated dualvibrator motor system generates a linear throwing motion. هذا العمل يطبق المادة, lifting smaller particles to the top layer for contact with the screen media while conveying larger particles forward.
3. تصنيف الحجم: Particles smaller than the deck aperture fall through to subsequent decks or collection chutes. Oversize material travels across each deck surface toward the discharge end.
4. Product Stream Discharge: Correctly sized fractions are discharged from designated chutes—typically as oversize (على سبيل المثال, +1"), middle product (على سبيل المثال, 1/4” x 1”), والغرامات (على سبيل المثال, رمل) —onto separate conveyors for stockpiling.

نطاق التطبيق & القيود:
نِطَاق: Ideal for primary sizing after crushing, final product classification (producing washed concrete sand, رمل ميسون, رقائق الحصى), and dewatering washed aggregates. Effective for materials with a bulk density typical of aggregates (1.51.8 طن / م³).
القيود: غير مصممة للالتصاق, highclaycontent materials without prescrubbing; maximum feed size is limited by deck aperture and impact resistance; performance is optimized within specified feed rate and moisture parameters.
