MEKA TWIN SHAFT MIXERS: HIGH CAPACITY AND EFFICIENCY

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 Twinshaft 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 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.

TWIN SHAFT MIXERS HIGHLIGHTS

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 Twin-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 out performs Hardox in terms of abrasion resistance and overall operating costs, as NI-HARD is proven to have up to 3 times the wear life of Hardox material.

WHY USING NI-HARD?

The Surface rigidity of Hardox materials is only approximately 3mm deep, therefore the abrasion resistance decrease rapidly, as the plates begin to wear. Unlike Hardox, 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 material and mixer size.

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 place 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 have maximum workable particle size of approximately 50mm, where as a single-shaft mixer can process materials containing particles up to 70mm in diameter and twin-shift mixers up to 150mm in diameter.

MIXER TOP COVER

Dustproof mixer cover is equipped with 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.

OPTIONAL ITEMS (When Supplied Separately)

DISCHARGE CHUTE

A discharge chute can be supplied upon request with or without 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 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 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 mixer can be supplied upon request.

SOFT STARTERS
