1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Are escalating operational costs and unpredictable availability eroding your primary crushing circuit’s profitability? Key challenges in primary crushing often include:

Thời gian ngừng hoạt động đột xuất: Bearing failures or mainshaft issues can halt your entire processing line, gây thiệt hại hàng chục nghìn mỗi giờ trong sản xuất bị mất.
Chi phí bảo trì cao: Thường xuyên, laborintensive liner changes and component wear directly impact your maintenance budget and manpower allocation.
Thông lượng không nhất quán: Fluctuations in feed size or hardness can cause chokefed conditions or poor cavity utilization, failing to meet designed tonnage targets.
Product Quality Issues: Poorly controlled discharge settings lead to offspec product size distribution, placing undue stress on downstream screening and secondary crushing stages.

Làm thế nào để bạn đạt được sự nhất quán, hightonnage reduction of runofmine material while controlling total cost of ownership? The solution lies in selecting a gyratory crusher engineered not just for capacity, but for reliability and operational efficiency.

2. TỔNG QUAN SẢN PHẨM: MÁY Nghiền xoay

A gyratory crusher is a stationary primary compression crusher, central to largescale mining and aggregate operations. It utilizes a gyrating mantle within a concave hopper to progressively reduce large feed material (typically up to 1.5m in size) to a manageable product for conveyor transport to downstream processes.

Quy trình hoạt động:
1. Lượng thức ăn ăn vào: Runofmine ore or quarry rock is dumped directly from haul trucks into the topmounted feed hopper.
2. Progressive Compression: The central mantle gyrates eccentrically within the fixed concave liners, continuously compressing and fracturing material as it travels down the crushing chamber.
3. Phóng điện: Vật liệu nghiền thoát ra qua lỗ xả ở phía dưới, with size primarily controlled by the vertical position of the mantle.

Phạm vi ứng dụng & Hạn chế:
Phạm vi: Lý tưởng cho công suất cao (1,000 10,000+ tph) primary crushing applications with abrasive, hard ores (ví dụ., đồng, sắt, vàng) or hard rock aggregates. Suited for continuous operation with direct truck or shovel feeding.
Hạn chế: Higher capital cost than comparable jaw crushers. Requires a stable, reinforced concrete foundation. Not suitable for lowtonnage operations or highly plastic/sticky materials without modification.
