Twin shaft mixers

ReMDC

DESIGN

. Recycling Specialist

Simem ReMDC is designed especially for waste treatment and industrial byproduct refurbishing.

Completely protected with wear liners and Ni-Hard cast iron paddles, hydro-dynamically designed to reduce wear and provide optimized mixing results, MDC versions have proven very useful for pumpable slurries, road pavements, and applications for treatment of industrial solid waste.

DESIGN

. 94% Efficiency

Simem ReMDC 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 extends gearbox life and reduces maintenance costs. The MixerMind^TM system provides complete surveillance of the mixing operation. The system provides service reminders and alerts upon the detection of abnormalities to avoid potential damages to mixer and its components.

DESIGN

. Automatic Greasing System

All Simem MDC 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.

RHYNO Twin shaft Mixer

The Simem RHYNO horizontal twin-shaft mixer represents excellence in the field of mixing thanks to a robust design, intuitive paddle adjustment and mixing action with the innovative DYNA-FLOW technology. This combination of engineering features allows us to realize several advantages, including the high quality of the concrete produced and the reduced maintenance cost of the mixer. RHYNO twin-shaft mixers have a compact concrete production capacity ranging from 1 to 4.5 m³. They are the ideal solution for a range of applications, including compact concrete, SCC, and RCC.

Dyna Flow Mixing System

A cutting-edge fluid dynamic simulation was used to support the design of
the paddle profiles and the connection points of the arms.
Developed in collaboration with the engineering innovation centre at
Padua University, the mixing action has been optimized to provide
additional mixing benefits to concrete producers, including:
• Improved mixing result for small aggregates
• Reduced mixing time and better energy performance
• Reduced wear on the blade connection points
• Less intensive mixer cleaning

Aggregate Skip Hoist

SIMEM RHYNO twin shaft mixers are available with an aggregate loading skip, bottom discharge (no tilting) and the heavy-duty winch high-power self-braking electric motor

Easy Maintenance

The mixer is the essential element of the system, and its maintenance is therefore fundamental

•An inspection door allows you to check the internal condition of the mixer.
• Arms and paddles are individually bolted, facilitating the easy replacement of spare parts.
• For maintenance of the most sensitive parts (joints, seals, reducers, etc.), the hood can be easily unhooked and partially opened following a tilting movement.
• A manual hydraulic pump allows the discharge door to be opened in case of emergency. The discharge door has limit switches that indicate partial or full opening and closing

High resistance Design

RHYNO twin shaft mixers are lined with stud-mounted high wear resistance liners. RHYNO paddles and arms are bolted to the twin horizontal shafts. The bolt on arm design allows for a various paddle positions to accommodate a variety of mix designs and ease of paddle adjustment.

This method and engineering technology also provides an optimized mixing result.

Automatic Greasing System

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

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

MSO Twin Shaft Mixer

Known for their reliability, unquestioned durability, and their output of high volume concrete production, MSO twin shaft mixers boast strong design, easy maintenance, and high quality componentry. This prescribed combination of engineered features provides the lowest maintenance cost per cubic meter of concrete produced. MSO mixers are available from 1 m3 to 9 m3 of concrete output. All MSO twin shaft versions are suitable for standard WET & SCC concrete,
RCC concrete, and MASS concrete (with large aggregates).

Mixing Solution

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.
