Trommel Screen
The trommel screen is usually used in the primary stage of placer gold ore to wash and screen the gold ore. The material on the screen is generally regarded as useless material. The under-sieve material which contains the gold is usually processed by centrifugal concentrator or gold sluice box continuously to upgrade the gold ore. The concentrates come from centrifugal concentrator could be processed by shaking table which is used to separate the gold from other minerals.
Main Feature of Trommel Screen
Trommel screens are constructed of high quality material, designed for high performance, high production rates, lower operating costs and lower maintenance.
- Configured for economical & efficient classification, screening and grading.
- Heavy duty trommel drum with lifters at the front to facilitate material break up.
- Screen replaceable for different mesh sizes.
- Multiple screen size.
- Easily changed screen plates.
- Largest processing capacity in the industry.
- Unique screen design, result in higher capacities, longer screen life and no material clogging.
- Heavy duty feed hopper and extension.
- Discharge chute.

Frequently Asked Questions
Q: What is the smallest gold particle size this concentrator can recover?
A: It can recover gold particles as fine as 0.004mm, with a recovery rate of approximately 97% for this size fraction.
Q: How often do I need to clean out the concentrate?
A: The cleaning-up cycle is typically 1–4 hours for vein gold and 2–6 hours for placer gold, depending on the grade of your ore.
Q: Does this machine require chemicals?
A: No. The centrifugal concentrator uses only water and electricity. It is a completely physical separation process with zero chemical pollution.
Q: Can I use this concentrator for tailings re-processing?
A: Yes. It is widely used to recover fine gold from old tailings, grinding circuit discharges, and flotation concentrates where fine gold has not been fully captured.
