Gold Trommel
Multotec’s gold mining trommels accurately classify ore masses by size as required by your application. They are engineered for high impact and abrasion resistance, and can handle feed rates up to 5 000 m3/hr.
Our range of gold mining trommels includes trommels with modular and cast panels and mill trommels. Trommels are fitted with screens with a wide range of apertures to achieve your required cut point according to the coarseness of the gold ore.
- Gold trommel diameter: 950 – 5 500 mm
- Gold trommel length: 1 200 – 5 500 mm
- Stress-relieved and NDT-tested trommel frames
- Real-time wear and performance monitoring with Hawkeye™
Multotec: a world leader in Gold Mining Trommels
Installed in a gold wash plant at the end of grinding mills fed by the sluice box, our gold mining trommels provide effective separation between coarse material and the fine slurry. These rotary screening systems are fitted with screen panels to achieve the cut points your process requires.
Our gold mining trommels are designed using the latest Finite Element Analysis (FEA) techniques. In considering process parameters such as load, the oversize, particle size distribution, solids SG and environmental conditions, Multotec’s design criteria allows for the reduction of structural operational stresses to improve the life and performance of the gold trommel.

Our Gold Trommel systems include:
Trommel Screens with Modular Panels
Trommels below 2.5 m in diameter use modular 305 x 305 mm screen panels. This modularity lowers maintenance and can easily adapt to your process requirements.
Large Trommel Screens with Cast Polyurethane Panels
Trommel diameters greater than 2.5 m, are supplied with heavy-duty cast polyurethane panels. Innovative designs maintain structural integrity, improve processing reliability and reduce downtime.
Mill Trommels
Especially suited in gold trommels, our high-capacity mill trommels enhance ore screening and washing performance during screening and classification.
Hawkeye™ Condition Monitoring
Hawkeye™ records and monitors wear and performance data of gold mining trommels. Through historical comparison of trommel performance, you can enhance predictive and preventative maintenance and reduce the chances of unplanned stoppages while improving equipment life.
Designing a Gold Trommel frame for your application:
The feed end flange is designed to be compatible with the mill flange. The machined face of the flange has a compatible bolting arrangement to the mill discharge trunnion flange.
The internal diameter of the feed-end flange or feed-end liners is designed to be the same diameter as the mill discharge or mill discharge liners. Gold trommel feed end liners can also have a slightly larger diameter to create an outwards step to compensate for wear of the mill discharge liners.
