Sand Gravel Mining Wholesaler Certificate
1. ОТКРЫТИЕ С УПРАВЛЕНИЕМ PAINPOINT
Управление предприятием по производству песка и гравия означает борьбу с постоянными, дорогостоящая неэффективность. Сталкиваетесь ли вы с этими общими проблемами?
Непостоянный исходный материал: Fluctuations in feedstock size and moisture content lead to frequent clogging, unplanned downtime for manual clearing, and suboptimal screening efficiency.
Высокие затраты на замену изнашиваемых деталей: The abrasive nature of aggregate rapidly degrades screen panels, компоненты привода, и подшипники, resulting in excessive spare parts inventory and labor costs for changes.
Неэффективное отделение мелочи: Inaccurate separation of fines from specification product leads to offspec material, wasted product in settling ponds, and potential revenue loss or customer rejection.
Чрезмерная вибрация & Обслуживание: Poorly balanced or lowquality vibrating screens transmit destructive forces to support structures and require constant bolt tightening, bearing checks, and foundational repairs.
Ограничения масштабируемости: 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.
Главный вопрос для руководителей предприятий:: 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. ОБЗОР ПРОДУКТА: HEAVYDUTY VIBRATING SCREEN FOR SAND AND GRAVEL
Данное оборудование имеет высокую производительность., 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, гравий, песок, and recycled concrete aggregates.
Операционный рабочий процесс:
1. Введение в фид: Raw, crushed aggregate is conveyed onto the feed box of the vibrating screen, который равномерно распределяет материал по всей ширине верхнего дека.
2. Стратификация & Разделение: A precisely calibrated dualvibrator motor system generates a linear throwing motion. This action stratifies material, lifting smaller particles to the top layer for contact with the screen media while conveying larger particles forward.
3. Классификация размеров: 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 (например, +1»), middle product (например, 1/4” x 1”), и штрафы (например, песок) —onto separate conveyors for stockpiling.
Область применения & Ограничения:
Объем: Ideal for primary sizing after crushing, final product classification (producing washed concrete sand, каменный песок, гравийная крошка), and dewatering washed aggregates. Effective for materials with a bulk density typical of aggregates (1.51.8 т/м³).
Ограничения: Не предназначен для липких, 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.
