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.

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.

High-performance Planetary Mixer

The mixing process is the most significant and delicate part of the concrete production process and choosing the right mixer for this task is extremely important. With features such as the central inlet of cement and water, as well as the modular design, the XENTRIX planetary mixer has taken planetary mixers to a new level, making them the obvious choice for producing high-quality concrete

Unique Design

The unique central inlet system allows cement and water to be transported into the mixer from above for homogeneous mixing thanks to the decentralized positioning of the main mixing arms. Mixing is highly efficient thanks to the integrated action of the central satellites (one or two, depending on the model) in planetary rotation for a centrifugal effect, combined with the centripetal effect of the perimeter scraper arms. The water is introduced into the mixer centrally and distributed in a 360° rain pattern. The centralized system includes an aspirator equipped with a fan that thus reduces dust during mixing.

Mixing tank

The mixing tank has been designed to achieve:

EXCELLENT WEAR RESISTANCE

The mixing tank is lined with interchangeable
special steel wear plates or alternative rubber.

FLEXIBLE CONFIGURATION

The tank consists of bolted modules that can be interchanged, making it possible to move or add discharge gates as needed.

EASY ACCESS FOR MAINTENANCE

Cleaning and maintenance are easy to perform through oversized inspection doors. All inspection doors are equipped with the safety devices required by applicable laws and regulations.

Mixing Paddles

The mixing blades are made of cast iron or a cast iron core coated with wear-resistant rubber material. They are designed to optimize material flow and minimize friction and abrasion of the aggregates. All support arms inside the mixing tank are designed in an optimal hydrodynamic shape.

. Mixing Efficiency

The mixing flow efficiency is due to the central stars in planetary rotation combined with different peripheral scraping shovel. The tank is internally covered by interchangeable panels made of wear resistant material, while the mixing paddles are manufactured with a Ni-Hard cast iron.

BETONWASH

A NEW RECLAMATION SYSTEM

BETONWASH is the definitive solution for reclamation of excess concrete and slurry water from cleaning of trucks, pumps, mixer, buckets, etc.

It separates solid materials over 0.15 mm diameter from the water through a spiral system rotating inside the inclined drum.

Slurry water is discharged from the BETONWASH by overflow into storage tanks and can be reused in the production of concrete or pumped into the WATERWASH.

WHY CHOOSING BETONWASH

Some advantages that make the BETONWASH the best choice are:

  • Extraction  of  solid  materials  through  a  spiral system without the use of any filters often found in reclamation systems.
  • Two  models  available  with  capacity  of  10  or  25 m³/hour.
  • Concrete can not get in contact with the drive unit ensuring mechanical integrity.
  • Minimal wear of surfaces inside the inclined drum due to the low rotation speed and of the extraction spiral and the use of residue aggregate as a wear liner.
  • With  a  wide  variety  of  possible  configurations, BETONWASH will fit any plant and site

HOW DOES THE WHOLE SYSTEM WORK

1. The process begins with the mixer or truck washout.
2. Extra concrete is diluted with clean water through pipes
3. The diluted concrete is discharged into the hopper, equipped with conveying pipes
4. BETONWASH works automatically until the complete extraction of aggregates (up to 0.15 mm)
5. The system periodically starts the agitator to avoid the settlement of fine materials
6. Slurry water is received from the WATERWASH from a specific deposit tank
7. WATERWASH separates water from concrete generating a “cake” of aggregates that can be reused in the concrete production
8. Clean water can be reused in the plant for site activity
9. A PH adjustment is available to check water conditions
