1. PAINPOINT DRIVE NOLEING

Шохойн чулууны карьер эсвэл боловсруулах үйлдвэрийг удирдах нь таны орлогод шууд нөлөөлдөг үйл ажиллагааны тодорхой саад бэрхшээлийг дагуулдаг.. 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. Үйлдвэрлэлийн алдагдсан цаг, эд ангиудыг хугацаанаас нь өмнө солих бүр ашигт ажиллагааг алдагдуулдаг. Үйлдвэрийн менежерүүдийн асуулт тодорхой байна: how can you create a more resilient, тустай, and costcontrolled primary crushing circuit? The answer often begins with optimizing the very first stage of size reduction.

2. БҮТЭЭГДЭХҮҮНИЙ ТОЙМ

Тухайлах ялгац гишүүн Apron Feeder бат бөх юм, continuousduty bulk material handling machine designed to extract, хэмжигч, 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. Унагдах: Heavyduty давхардсан тогоо (хормогч) move under the material stockpile or dump hopper.
2. Дамжуулах: A powerful chainandsprocket drive system pulls the pans along a rugged frame.
3. Хэмжилт: The feeder’s speed is precisely controlled to deliver a consistent, predetermined tonnage.
4. Ахах: 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 (ихэвчлэн 80% of pan width) and are less suited for fine, powdery materials where containment is an issue.
