1. PEMBUKAAN PAINPOINT DRIVEN

Are you scaling your gold recovery operations only to be constrained by washing and scrubbing capacity? Suapan tidak konsisten, kandungan tanah liat yang tinggi, and inefficient fines recovery directly impact your bottom line. Pertimbangkan cabaran biasa ini:
Kapasiti Terhalang: 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.
Excessive Downtime & Penyelenggaraan: Kegagalan galas yang kerap, membutakan skrin, 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.
Air Tinggi & Penggunaan kuasa: 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. GAMBARAN KESELURUHAN PRODUK

The FDA Approved 500 Loji Pencuci Perlombongan Emas TPH adalah tugas berat, 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.

Aliran Kerja Operasi:
1. Suapan & PraSkrining: Runofmine material is fed via conveyor into a robust hopper with a grizzly section to remove oversize rocks (>75mm).
2. Menggosok Intensif: 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. Saringan yang cekap & Pengelasan: Scrubbed material passes over modular screen panels (typically 10mm), with undersize reporting to downstream recovery (pintu air, emparan) and oversize conveyed to waste.

Skop Permohonan: Ideal for largescale alluvial gold operations, placer mining projects, and heavy mineral sands beneficiation requiring highvolume feed processing.

Batasan: 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.
