1. What is a Rotary Trommel Screen Gold Washing Plant used for?
It is used to wash, classify and separate alluvial (placer) material to recover coarse and fine gold by screening, scrubbing and gravity concentration.
2. What throughput (capacity) can I expect from a 'large capacity' unit?
Large capacity units typically range from about 30 t/h up to several hundred tons per hour depending on feed material, feed size, moisture and machine configuration. Contact the manufacturer with your ore characteristics for an accurate capacity estimate.
3. What feed size can the rotary trommel accept?
Most trommels accept feed up to approximately 200–300 mm (8–12 inches). Oversized material should be pre-screened or crushed to avoid blockage and excessive wear.
4. What gold particle sizes can this plant recover?
The plant is effective for coarse and medium-fine gold. With proper configuration (sluices, shaking tables, centrifuges, classifiers), recovery can extend to fine gold particles — often down to a few tens of microns — but exact recovery depends on deposit characteristics and downstream concentrators.
5. What are the main components of the washing plant?
Typical components include the rotary trommel (screen drum), feed hopper and conveyor, scrubber or log washer, classifiers or vibrating screens, sluice boxes or riffles, pumps, water recycling/tailings system and control panels. Additional concentration units (shaker tables, centrifuges) can be added.
6. How much water does the plant consume and can water be recycled?
Water consumption depends on configuration and capacity. Many plants are designed with settling tanks and water recycling systems to minimize fresh water use. Recycling rates and exact consumption should be specified per project.
7. What power supply options are available?
Plants can be powered by electric motors (grid or generator) or by diesel engines for remote sites. Power requirements depend on model and size; provide your preferred power source and site details to get exact power specs.
8. Is the equipment mobile or fixed?
There are skid-mounted and trailer or tracked mobile versions for easy relocation, as well as stationary plant installations for long-term operations. Mobility options vary by model.
9. What are the typical recovery rates for alluvial gold?
Recovery rates vary widely with deposit type, particle size distribution and plant configuration. Typical gravity recovery for coarse gold can be high (often 80–95% for coarse nuggets) but fine gold recovery requires optimized plant setup. Site testing is recommended.
10. What maintenance is required and what are common wear parts?
Regular maintenance includes checking bearings, sprockets, trommel screen panels, pumps, hoses, and lubrication. Common wear parts are trommel screen panels/mesh, liners, sluice riffles, pump impellers and conveyor belts. A preventive maintenance schedule prolongs service life.
11. How long does installation and commissioning take?
Installation time depends on scope and site conditions. Small modular units can be set up in a day or two; larger plants may take several days to a few weeks including civil works and commissioning. Supplier assistance speeds up the process.
12. What environmental and regulatory issues should I consider?
You should comply with local permits for water use, discharge, tailings management and land disturbance. Using water recycling, settling ponds and responsible tailings disposal reduces environmental impact and helps meet regulatory requirements.
13. Do you offer customization and additional concentration modules?
Yes. Plants can be customized with different trommel lengths, screen apertures, scrubber types and added concentrators (shaker tables, centrifuges, jigs, hydrocyclones) to optimize recovery for specific deposits.
14. What operator skills are needed to run the plant?
Basic mechanical aptitude and training in plant operation, safety procedures and process control are required. Many suppliers provide operator training during commissioning.
15. What after-sales support and warranty are provided?
Typical offerings include a manufacturer warranty (commonly 12 months, subject to terms), spare parts supply, remote or on-site technical support and commissioning assistance. Confirm exact warranty and support terms with the supplier.
