Achieving the desired homogeneity and workability of modern concrete mixtures within the shortest period possible is often the most critical phase of concrete production, therefore, the need for reliable, high-quality mixing equipment is essential. A MEKA Concrete Plant with a MEKA Single Shaft Concrete Mixer at its heart is a combination you can always rely on. MEKA offers an extensive range of high-performance concrete mixers – Single Shaft, Twin Shaft, and Planetary with a variety of different capacities, ensuring we comply with every concrete mixing requirement. MEKA Single Shaft Concrete Mixers have proven to be reliable and built to the highest quality, resulting in MEKA equipment being the choice of many professionals in over 70 countries around the world.

HEAVY AND ROBUST

• MEKA Single Shaft Concrete Mixers offer long life, as they are 5-10% heavier than most of their equivalents on the market today due to their robust steel structure and thick interior abrasion-proof linings.

NI-HARD IS THE KEY

• We offer NI-HARD alloy cast wearing linings in our Single Shaft Mixers as standard. This particular alloy is well known for its abrasion resistance and is used in a variety of different applications, such as concrete mixing, coal and other mineral grinding, slurry pump manufacturing, concrete pumping, piston manufacturing, gears manufacturing and many others. Despite being more expensive at the outset, Ni-Hard outperforms other alloys in terms of abrasion resistance and overall operating costs as Ni-Hard is proven to have up to 3 times the wear life of standard alloy materials.

WHY USING NI-HARD?

• The rigidity of NI-HARD material is identical through every section and layer, therefore, abrasion rates do not vary. As the plates begin to wear and subject to the rigidity of the aggregates used, the life expectancy of the Ni-Hard mixer wear parts can reach a production capacity of up to 1,000,000 m³, depending on the mixer type and its volume.

DISCHARGE CHUTE

• A discharge chute can be supplied upon request with or without a rubber chute.

UNIQUE BEARING AND SEAL DESIGN

• The specially designed Bearing and Single Shaft Mixer seal group consists of a number of metallic and polyurethane components. The bearings are placed on the outside of the mixer in the specially designed housing, which prevents the ingress of cementitious grouts if a seal failure should occur, therefore, with the correct routine maintenance, the life expectancy of each bearing can exceed 500,000 m³ of production. The Labyrinth seal structure encapsulates the grease provided by the automated greasing system to create a seal, preventing the grout from penetrating the bearing.

PERFECT LUBRICATION SYSTEM

• The centralized automatic lubrication system continuously supplies the mixer labyrinth seals with sensors on each seal, to ensure you are informed of a failure before it is too late.

WATER DISTRIBUTION SYSTEM

• We offer water distribution pipe with distribution nozzles working by gravity by default. Several discharge types and sprayers, gravity or pressurized are available upon request according to the application.

MIXER DISCHARGE GATE

• The discharge gate is operated pneumatically. Position switches enable individual adjustments for controlling the flow of concrete through the discharge gate.

POWER PANEL

• All MEKA mixers come pre-wired and connected to the junction power box.

MAINTENANCE COVER

• A wide maintenance hatch with safety switches for secure and easy access for maintenance is supplied as a standard.

DRIVE TRAIN TO LAST

• High-quality engines and gear-boxes from the best manufacturers with perfectly chosen RPM’s lower energy consumption and provide a long-lasting service life of the mixers. The final transmission is a strong and simple chain mechanism with easy access to bearing group and seals.

UNIQUE PADDLE STRUCTURE

• The Single Shaft Mixer paddle structure has been specifically designed for strength and abrasion resistance. Each Pallet group attached to a helicoidal main shaft has been reinforced against failure and the concave structure improves life expectancy. The design and quality of our mixer paddle structures are market leading and the quality is often compared to many German products on the market today. The life expectancy of the mixing group is equal to the abrasion-proof liners and cast thickness of the mixer structure, therefore, the life expectancy of MEKA equipment is more than often, in excess of many of our competitors.

MIXER MOISTURE PROBE

• A microwave moisture sensor reading at 25 times per second and combined with on-board functionality such as signal processing, smoothing and averaging accurately measures the moisture content of the material as it passes over.

MIXER TEMPERATURE SENSOR

• No matter what is the season, cold or hot, the purpose of this sensor is to ensure that the temperature of the mix is within acceptable levels.

SAFETY POWER TAKE-OFF KIT

• For the safety of the working environment, we offer a wide range of safety power take-off kits for mixers and other parts of concrete plants.

PRESSURIZED WATER DISTRIBUTION

• According to the application, we can offer a low-pressure water spray system for water discharge and special distribution nozzles.

MIXER TOP FILTER

• A separate filter or dust bag for the mixer can be supplied upon request.

SOFT STARTERS

• Soft starters for the smooth start-up of the mixers are available upon request.

SWIVEL DISCHARGE CHUTE

• We can offer a swivel discharge chute to protect the mixer trucks from a concrete leak on a drive through layouts.
