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.

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.

VORTIMIX

Simem Vortimix collidal mixer

High-Share Colloidal Mixer

The Vortimix high-shear colloidal mixer is recognized as the most efficient method of mixing bentonite, cement, fly ash, and slag with water. The intense mixing action results in homogeneous and stable mixes. Colloidally mixed cementitious products are found to better resist bleed (separation and settlement of solids) and provide higher compressive strengths in comparison to materials prepared in lower-energy type mixers.

Quality and speed

VortiMix is an advanced high-shear colloidal mixer by Simem. The VortiMix can rapidly mix cementitious grouts as low as 0.45:1 water:cement ratio (by weight). Hydrated bentonite mixes are rapidly prepared in the VortiMix, which yield improved gel strengths and reduced hydration times for applications where pre-hydrated bentonite is necessary.

Vortex

Recirculation “ports” allow mixture to re-enter mixing vessel with velocity, causing turbulent material flow. An automated pinch-valve network determines GROUT mixture route. Pinch-valve actuation allows mixture to recirculate then discharges GROUT for storage and pumping, which allows a quick removal after completing the job

WATERWASH

A NEW RECYCLING SOLUTION

WATERWASH is made up of large filter panels, specially designed for contact with concrete.

By applying the correct pressure, these filter panels separate the water from the fines; the water can be used for other purposes or put into a new concrete batch cycle.

A pH metering and adjustment system is available if the mix design requires pH-neutral water.

AN EASY WAY FOR RECYCLING

WATERWASH can be easily transported since it is installed into a pre-wired and pre-plumbed standard container equipped with lights, insulation, and heating as necessary for the climate it will operate in.

Through a modern PLC system, the operator has complete control of all aspects of the unit and can set the correct filtering for job site specifications.

WATERWASH 1.0 has the capacity to treat up to 10 m3/h of slurry water, while the 2.0 version can treat up to 20 m3/h.

The solid content in the discharge water can be as low as < 0,1 gr/lt.

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
