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. With each and every MEKA Concrete Plant, a MEKA Twin Shaft Concrete Mixer is at its heart, which is a combination you can always rely on. MEKA offers an extensive range of high-performance concrete mixers – Single Shaft, Twin Shaft, Planetary or Pan with a variety of different capacities, ensuring we comply with every concrete mixing requirement. MEKA Twin 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 Twin 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.

UNIQUE PADDLE STRUCTURE

• Twin Shaft Mixer paddle structure has been specifically designed for strength and abrasion resistance. Each Pallet group 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. MEKA Twin Shaft Mixers are capable of blending materials with particle sizes of up to 150mm in diameter. The paddle angle of 45° also means it can withstand higher loads, therefore, it is capable of mixing zero slump concretes, RCC mixes and all types of ready mixed concrete mixtures.

UNIQUE BEARING AND SEAL DESIGN

• The specially designed Bearing and Twin 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.

IN RCC GRAIN SIZE MATTERS

• Twin Shaft Mixers normally work with a particle size of approximately 50mm. However, in RCC applications, twin-shaft mixers can mix aggregates up to 150mm in diameter.

MIXER TOP COVER

• Dustproof mixer cover is equipped with a wide maintenance hatch with safety switches, supported by industrial gas shocks for secure and easy access for maintenance. Several connection types for loading of materials and other controls are available.

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

• A hydraulic rotary discharge gate with position sensors is supplied as standard. Several options for twin discharge legs are available upon request.

HYDRAULIC DRIVE FOR DISCHARGE GATE

• The discharge gate is driven by a hydraulic power pack, which ensures the full open and close. Manual operation with the help of a manual pump in case of an emergency is possible.

MAINTENANCE PLATFORM

• All MEKA Twin Shaft mixers are supplied with a maintenance platform as a standard.

DISCHARGE CHUTE

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

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 the ceramic faceplate

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.

AUTOMATIC HIGH-PRESSURE WASHOUT SYSTEM

• An optional mixer washout system with a 100-bar water pump and two rotating heads (10 nozzles) can be supplied upon request.

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.

TWIN-DISCHARGE

• Two-way discharge can be supplied as an option to maximise the capacity of the plant and to ease the operation.

MORE POWER

• More powerful motors and gearboxes can be supplied according to the application, such as heavyweight concrete with lead or iron ore, low slump concrete and others.

WIDE AFTER-SALES NETWORK

• We are always around to support our equipment with our regional offices, dealers and spare part warehouses worldwide.
