Mixer equipment manu- facturing company Eirich has developed and tested its new R28 intensive mixer to capacities of 5 500 ℓ, creating a versatile, large-scale mixing solution that is particularly suited to ore pelletisation and preparation.

The R28 intensive mixer, which is supplied and supported in South Africa by industrial process company Birkenmayer, features a throughput rate of 650 t/h. This capacity is a result of high-tech design, which ensures intensive mixing during operation.

“Maximum energy is directed into the mix by a set of rotating mixing tools and a rotating pan. These components efficiently separate the transportation process from the high-speed mixing, making the R28 suitable for use in various applications, ranging from ore processing and cement mixing to the mixing of rubber compounds and emulsions that require true homogenisation,” says Birkenmayer business development manager Louis Eksteen.

The intensive mixing principle is also employed to limit wear and tear for lower maintenance and more economical operation.

“Birkenmayer will analyse and design mixing processes for its clients to determine optimal tilt angles, mixing speeds and durations, as well as other aspects which affect final mix quality. The result is a complete mixing solution that includes the mixer’s feeding systems, measurement devices and other process- related components,” he states.

The R28 intensive mixer supports various rotor drive systems, including conventional and high-torque synchronous motors. Power inputs can also be adapted for specific applications, improving the energy consumption of the plant.
