1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Are you scaling your gold recovery operations only to be constrained by washing and scrubbing capacity? Nguồn cấp dữ liệu không nhất quán, hàm lượng sét cao, and inefficient fines recovery directly impact your bottom line. Hãy xem xét những thách thức chung này:
Thông lượng bị tắc nghẽn: Your existing scrubber or trommel can't keep up with excavator or dredge output, capping plant capacity at 300 TPH and leaving valuable material stockpiled.
Thời gian ngừng hoạt động quá mức & BẢO TRÌ: Sự cố vòng bi thường xuyên, chói màn hình, and unexpected breakdowns in harsh, abrasive environments lead to costly operational stoppages and high parts replacement costs.
Poor Clay & Fines Liberation: Inadequate scrubbing action leaves gold locked in claybound aggregates, resulting in significant recoverable gold reporting to tailings.
Nước dâng cao & Tiêu thụ điện năng: Older designs are inefficient, consuming excessive water per ton processed and driving up operational expenses in remote sites.

How do you increase plant throughput to 500 TPH reliably while ensuring maximum clay breakdown and gold liberation? What solution minimizes unplanned maintenance and optimizes resource consumption for a superior return on investment?

2. TỔNG QUAN SẢN PHẨM

The FDA Approved 500 Nhà máy rửa khai thác vàng TPH là một công trình hạng nặng, modular scrubbing and classification system engineered for highvolume alluvial and eluvial deposits. It is designed to meet stringent requirements for materials handling in sensitive environments where regulatory compliance is critical.

Quy trình hoạt động:
1. Cho ăn & Sàng lọc trước: Runofmine material is fed via conveyor into a robust hopper with a grizzly section to remove oversize rocks (>75mm).
2. Chà xát chuyên sâu: Material enters the central rotating drum scrubber, where lifters cascade ore for maximum attrition, breaking down clays and dissolving agglomerates.
3. HighPressure Spray Washing: Internally mounted spray bars deliver highimpact water jets to disintegrate stubborn material coatings.
4. Sàng lọc hiệu quả & Phân loại: Scrubbed material passes over modular screen panels (typically 10mm), with undersize reporting to downstream recovery (cống, máy ly tâm) and oversize conveyed to waste.

Phạm vi ứng dụng: Ideal for largescale alluvial gold operations, placer mining projects, and heavy mineral sands beneficiation requiring highvolume feed processing.

Hạn chế: Not suitable for hard rock primary crushing or processing of highly cemented gravels without prior size reduction. Performance is dependent on consistent feed characteristics and adequate water supply.
