All mixing tanks of the Simem MSO twin shaft mixers are fully lined with high resistance tiles. Paddles and arms are bolted on two primary mixing shafts. The mixing arm design allows for different configurations to accommodate specific recipe applications. Hydro-dynamic engineering contributes to mixing paddles and arms reduce wear. This research and engineering technology also provides an optimized mixing result.
MSO mixers are available from 1.5 yd3 to 12 yd3 of concrete output. All MSO twin shaft versions are suitable for standard WET & SCC concrete, RCC concrete, and MASS concrete (with large aggregates).
Simem MSO twin shaft mixers are equipped (as standard) with high efficiency planetary type gearboxes with a mechanical efficiency of up to 94%. Integrated oil cooling systems guarantee a proper working temperature which extended gearbox life and reduce maintenance costs.
All Simem MSO mixers are equipped (as standard) with four special labyrinth mixer shaft seals. Seals are constantly lubricated by an electric drive grease pump with sensors to ensure proper functioning.
