1. PEMBUKAAN PAINPOINT DRIVEN

Menguruskan kuari batu kapur atau kilang pemprosesan memberikan halangan operasi yang berbeza yang secara langsung memberi kesan kepada keuntungan anda. 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. Each hour of lost production and every premature component replacement erodes profitability. Soalan untuk pengurus loji adalah jelas: how can you create a more resilient, cekap, and costcontrolled primary crushing circuit? The answer often begins with optimizing the very first stage of size reduction.

2. GAMBARAN KESELURUHAN PRODUK

The Apron Feeder adalah teguh, continuousduty bulk material handling machine designed to extract, meter, 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. Pengekstrakan: Kuali bertindih tugas berat (apron) move under the material stockpile or dump hopper.
2. Pengangkutan: A powerful chainandsprocket drive system pulls the pans along a rugged frame.
3. Pemeteran: The feeder’s speed is precisely controlled to deliver a consistent, predetermined tonnage.
4. Pelepasan: 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 (biasanya 80% of pan width) and are less suited for fine, powdery materials where containment is an issue.
