Wanshihengtong WS1240 Gold Trommel Screen | 50‑80t/h Large‑Capacity Alluvial Gold Washing Machine
01. Product Introduction
Wanshihengtong WS1240 gold trommel screen is a commercial large‑capacity rotary washing‑screening equipment specially developed for medium‑to‑large scale placer gold and alluvial gold mining projects. Equipped with thickened extended drum Φ1200×4000mm, this model achieves stable processing capacity of 50‑80 tons per hour, meeting high‑volume production demands of large‑scale gold‑washing plants.
Compared with medium‑size trommel equipment, WS1240 optimizes drum rigidity, material turnover space and full‑coverage high‑pressure water‑spray scrubbing system, effectively solving industry pain points including poor clay dissociation, screen clogging and insufficient single‑machine throughput when processing high‑mud raw ore. It fully separates gravel, rock waste and gold‑bearing fine sand, greatly improving gold washing efficiency and mineral recovery rate.
This gold trommel supports stationary fixed installation and mobile trailer‑mounted customization. It can work independently or combine with sluice box, centrifugal gold concentrator and shaking table to form a complete alluvial gold beneficiation production line. Widely deployed in Africa, South America and Southeast Asia large commercial gold mines, it is a reliable high‑output core washing equipment for global mining investors.
02. Core Performance Features
Large‑Drum High‑Throughput Design
Adopt Φ1200×4000mm lengthened thick‑wall drum structure. Optimized rotating speed and inclination angle guarantee sufficient material tumbling and scrubbing time, realizing stable continuous 50‑80t/h feeding and washing capacity for large‑scale gold‑washing projects.
Full‑Coverage High‑Pressure Clay Scrubbing System
Multi‑row high‑pressure spray nozzles are arranged inside the drum to form three‑dimensional water flushing. It fully scours sticky clay wrapped on gold‑bearing gravel, breaks mud clumps and releases wrapped fine gold particles, reduces fine‑gold loss and lifts overall recovery performance.
Heavy‑Duty Wear‑Resistant & Anti‑Clogging Screen Mesh
Screen mesh uses high‑strength manganese steel material with anti‑blocking hole‑structure design, resisting gravel impact, abrasive wear and mud blockage, adapting to long‑time heavy‑duty operation for high‑clay, high‑impurity ore. Screen aperture can be customized according to customer ore particle‑size requirements.
Dual‑Power & Flexible Deployment Options
Standard electric motor configuration, diesel generator power optional for remote mining sites with unstable grid power. Choose stationary foundation installation or mobile trailer chassis for fast site relocation and rapid commissioning.
High Compatibility with Subsequent Beneficiation Equipment
Standardized feeding and discharging interface perfectly matches sluice mats, centrifugal concentrators and shaking tables. It realizes classified recovery for coarse gold and fine gold, satisfying full‑process configuration requirements for large gold‑washing production lines.
Robust Structure & Low Maintenance Cost
Reinforced heavy‑duty steel frame improves overall equipment stability. Consumable parts adopt universal standardized design for convenient replacement and daily service. Low vibration and low‑failure‑rate operation effectively cut down later‑stage operation‑maintenance expenditure.
03. Working Principle
Raw gold‑bearing sand‑gravel materials are evenly fed into the rotating drum of WS1240 gold trommel screen. Along with continuous drum rotation, raw ore keeps tumbling, rolling and rubbing inside the cylinder. Meanwhile, built‑in high‑pressure water‑spray system continuously flushes materials to dissolve and strip sticky mud and clay impurities wrapped on ore particles.
During washing and scrubbing, qualified fine gold‑bearing sand passes through screen holes and falls into the lower‑level collection system for further gravity separation and concentration. Large‑size stones and waste rock are automatically discharged from drum tail. The whole washing‑screening workflow runs continuously and automatically, completing efficient separation of gold‑bearing feedstock and waste material, and promoting gold‑washing efficiency and recovery rate.
