1. ОТКРЫТИЕ С УПРАВЛЕНИЕМ PAINPOINT

Управление карьером известняка или заводом по переработке известняка представляет собой определенные операционные препятствия, которые напрямую влияют на вашу прибыль.. Are you contending with unpredictable crusher blockages from sticky, highmoisture feed? Is excessive wear on primary crushing components driving unsustainable maintenance costs and unplanned downtime? Perhaps inconsistent feed size to your secondary crushers is creating bottlenecks, limiting overall plant throughput and compromising final product specification. Каждый час простоя производства и каждая преждевременная замена компонентов снижают прибыльность.. Вопрос для руководителей предприятий ясен: how can you create a more resilient, эффективный, and costcontrolled primary crushing circuit? The answer often begins with optimizing the very first stage of size reduction.

2. ОБЗОР ПРОДУКТА

The Apron Feeder является надежным, continuousduty bulk material handling machine designed to extract, метр, and feed raw materials like runofquarry limestone at a controlled rate to primary crushers or processing plants. Its operational workflow is engineered for reliability in the most demanding environments:
1. Добыча: Сверхмощные перекрывающиеся сковороды (фартук) move under the material stockpile or dump hopper.
2. Транспортировка: A powerful chainandsprocket drive system pulls the pans along a rugged frame.
3. Измерение: The feeder’s speed is precisely controlled to deliver a consistent, predetermined tonnage.
4. Увольнять: Material is delivered in a steady stream to the downstream crusher or conveyor.

Application scope includes primary feeding under dump hoppers, regulating feed to gyratory or jaw crushers, and handling heavy impact loads from large quarry trucks. Key limitations involve maximum lump size (обычно 80% of pan width) and are less suited for fine, powdery materials where containment is an issue.
