Multotec trommel screens are installed at the end of grinding mills and scrubbers for vibration-free processing, delivering an effective material separation as volumes are fed down the inclined rotating drum across application-determined screen media. Trommel screens from Multotec are hard-wearing, high-impact and abrasion-resistant mechanical screening solutions.
Multotec has been supplying trommel screens to the mineral and solid-waste processing industries since 1982, during which time we have perfected the ability to size and customise trommel screens to suit the application. The core trommel screens range from 950 mm diameter to 5 500 mm and from 1 220 mm to 6 000 mm long, with a mass of 800 kg to 30 000 kg. Process guarantees are supplied with all trommel screens sized by Multotec.
The trommel screens comprises the rubber-lined steel frame and replaceable screening surface. Several modifications can be made to this basic trommel screen, including a dual media screen to produce a two-fraction material grading, as well as hydraulic or mechanical self-propulsion.

Trommel screens are designed using the latest Finite Element Analysis (FEA)techniques to reduce fatigue stresses and improve trommel screen frame life. Factors such as load on the trommel screen, the oversize, particle size distribution, solids SG and operating conditions are taken into account when the trommel screen is designed.

Designing an application-enhancing trommel screen frame
The feed end flange is designed and constructed to be compatible with the mill or scrubber flange. The flange has a machined face with a compatible bolting arrangement to the mill / scrubber 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. The 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.
Multotec provides tailor-made, process-specific trommel screens in several forms to optimise drainage and sizing requirements.
This is available to the South American and African markets.
