Continuous Flow Concrete Mixer

MDC Continuous Flow Mixer adopts twin shaft technology and is specifically designed for Zero-Slump Concrete and Roller-Compacted Concrete (RCC).
Completely protected with wear liners and Ni-Hard cast iron paddles, hydrodynamically designed to reduce wear and provide optimized mixing results, MDC versions have proven very useful for pumpable slurries, road pavements, and applications for the treatment of industrial solid waste.

Special Paddles

Paddles are made of high strength cast iron and are hydrodynamically shaped to optimize the flow of materials and minimize surface wear. All the blades and mixing arms are screwed to the main axes to allow easy interchangeability and maintenance. Thanks to the unique design, the mixing arms can be installed in different configurations depending on the size of the aggregates, thus ensuring excellent mixing performance.

Gear Boxes

SIMEM MDC mixers are designed for maximum productivity and long-term reliability of service. Driven by electric motors, the twin-stage planetary gearboxes, rated at 94% efficiency, are connected to the main shafts with articulated joints, which virtually eliminate the transmission of any possible force from the mixing shafts to the reducer output shafts.

Multifunctional

MDC mixers were originally designed for material blending, low slump concrete, and RCC. Trough the decades Simem have evolved the design into a range of different models that have proven very useful in many applications. This includes:
• Lengthened version to support longer mixing retention times
• Overflow discharge for the mixing of very fluid materials
• Stainless steel mixing tank for use in corrosive environments
SIMEM MDC series mixers are used in numerous projects worldwide, including the construction of dams, roads, and for the production of backfill in underground mining.

Special Mining System

With protection wear liners, Ni-Hard cast iron paddles, and hydro-dynamic infused design for further wear reduction, the SIMEM MDC Paste mixer provides an optimal result for producing Paste backfill. MDC creates a powerful production capability, providing mining companies with a robust paste mixer, tailored for mine backfill applications. The MDC Twin-Shaft Mixer for the production of paste backfill can be designed to accommodate the most challenging paste plant environments. With its DUAL-PURPOSE DESIGN, the MDC Twin-Shaft Mixer for mine backfill applications addresses paste production environments challenged by tough materials. When purposed as a conditioning mixer, the Simem MDC fractures material to a consistency ideal for superior paste quality

Automatic Greasing System

All Simem mixers are equipped with labyrinth mixing shaft seals. An electrically driven, sensor monitored grease pump, constantly lubricates the seals to safeguard mixer operation and reduce routine maintenance activities.
