THE CENTRALS

From consulting to design, including construction and execution, KNIELE Mischtechnik offers the right installation for every need:

In the program :

  • tower batching plants
  • step plants
  • star/scraper plants
  • row type plants
  • pocket silo plants
  • mobile mixing plants
  • special mixing plants

 

 THE VERTICAL CONCRETE MIXING PLANT

Between 100 m3 and 1 000 m3 of material can be stored in the distinctive tower plant aggregate silo with a diameter from 5.75 to 10.5 m. Loading can be effected at 16° by conveyor belts (even), by steep-incline conveyor belts (napped) at 30°, by bucket-type elevator or by S-conveyor.
The design allows for loading without additional staff.
Processing of the aggregates is possible even at extremely low temperatures if the silos are equipped with an insulated cladding and an integrated heating.
The installation of several mixers ensures a very high effectiveness of the plant.
An independent shipping of transit-mixed and ready-mixed concrete for a construction site as well as an independent production of transit-ready concrete and mortar or flowing screed (if an anhydrite mixer is integrated into the plant) is possible.

STEP PLANT

Due to its low design height this low tower type is used wherever officially predefined height limitations must be observed.

ROW-TYPE PLANT

e.g. for block plants, because many different aggregates are needed.

Loading by double belt or single belt conveyor, or special lift e.g. for double broken and double screened chips, to enable a sorted loading.
Feed hopper over ground for rear dump trucks or underground with cover grating.

MOBILE MIXING PLANTS AND SPECIAL MIXING PLANTS CONSTRUCTION

KNIELE mixing plants in mobile and partly mobile design are the solutions for concrete production at any time and any place.

Even if designed the same way, stationary and semi-mobile plants differ because of the specific techniques of connecting the parts of the plant, which enable an easy assembly and disassembly of the semi-mobile plants. This is also true for the electronics, water supply and pneumatics. With semi-mobile plants, the transport dimensions for problem-free road transport are of course observed.

Entirely mobile plants can be mounted onto railway wagons an can thus be transported to their destination every day.

We develop the right solution for each and every individual case. Expertise and the co-operation with the customer are what is needed here.

SPECIAL PLANTS

The KKM conical mixing machine with tight closure makes it possible to produce very fluid concretes and suspensions, which is not possible with a screw cap (especially used for the production of ultra-high performance concretes, mortars for wedging and sealing for waste , etc.).

CONICAL MIXER KKM

KNIELE revisits mixing

The KNIELE taper mixer, which was patented in 2000, is based on a revolutionary kneading principle. Two counter-rotating agitators make it possible to quickly generate a homogeneous mass in a conically shaped mixing space. The first agitator consists of a conical worm, with propellers or blades arranged helically. The second agitator comprises a mixing arm associated with a scraper, which rubs against the wall of the mixing tank. The central helical agitator conveys the product to be kneaded in a vertical position and applies a rotation to it. The agitator arm, offset from the central axis, operates in the opposite direction of this rotational movement. The two contrary and transversal kneading streams thus produced make the entire contents of the kneader powerfully swirl, resulting in fast and efficient kneading of the components.

The cone mixer and its properties

  • Optimal mixing effect thanks to the new mixing principle !
  • Reliable break-up of cement agglomerates !
  • Bar-free addition of colors !
  • No loss of quality when mixing small quantities !
  • Entire discharge within the shortest time !
  • Conical, space-saving design !
  • Low pollution level-easy and quick manual or automatic cleaning !
  • Absolutely low noise !
  • Start with fully loaded mixer is possible !
  • Versatile application ! Mixing of concrete of any texture, steel fibre concrete, SCC and UHPC, air-entrained concrete, polystyrene concrete, mortal, any dry bulk products, sludge, dusts, etc.


High efficiency through

With the independent speed control of the two agitators, especially the inner agitator, liquid and earth-moist concrete can be produced by the cone mixer. It is ideally suited for special concrete such as UHPC and SCC, fibre concrete, lightweight concrete, heavy concrete, etc. The indefinitely variable control allows for precise adjustment for the respective mixing product. These optimizations significantly reduce the mixing time of such special concrete.

Dry materials from dry mortar to food are also no problem for the cone mixer. Many educational establishments, material test centers and research institutes use this mixer as a laboratory mixer for the development of new special concrete.

  • Short mixing and discharge cycles
  • Short cleaning times
  • Cement and pigment saving
  • Reduction of waste
  • Low maintenance effort
  • Reduced wear and tear surfaces

In order to produce UHPC, the mixer can be equipped with a special agitator tool and a special drive with a speed of up to 1 000 rpm. As a result, the mixing time can be reduced to as low approx.. 2 minutes.

LABORATORY INTENSIVE MIXER KKM-RT 15/22.5

The KNIEL KKM-RT 15/22.5 combines a laboratory intensive mixer with a rheometer that provides the rheological properties of the mixture in either relative or absolute units. A mixer probe for moisture analysis and a dosing unit for addition of mix development.
Samples of various concrete types, or any quality and quantity, can be produced with this mixer to carry out classic fresh concrete tests such as slump spread, slump flow measure, VdZ (German Cement Plant Association) funnel, LCPC box, etc.

Material discharge and mixer cleaning

Almost all of the mixture drops into a previously positioned container beyond the mixer under the influence of gravity.
Following the discharge of the mixture, the flap is closed, the drum is filled with water and the mixing tools are run at high speed. Deposits on the mixing tools come off and are carried out with the water when the closure flap is reopened.

Mixing tools

To increase mixing intensity, minor improvements were made to the conical mixer’s mixing tools. The disagglomeration of fine materials and the separation of fine fibers will be significantly improved and accelerated with the arrangement of short pins on the outer edges of the mixing paddles.

LABORATORY INTENSIVE MIXER KKM-RT 15/22.5

LABORATORY MIXER KKM-L FROM 30 AT 375 LITER

KNIELE forced-action laboratory mixers are supplied as a KKM-L conical mixer and offer a very intensive and uniform mixing result. Thanks to their conical shape, they also make it possible to mix very small quantities by obtaining an excellent quality. Similarly, their geometric shape ensures easy emptying, extremely fast and without residues. The filling of the tank is easily done from the top.

With the conical mixer, quality concretes of all types (for example self-compacting concretes or light concretes) can be produced very quickly, with a high mixing quality. It is suitable not only for the mixing of concrete, but also for all other areas of application of dry mix, such as the production of light plasters, dry mortars, polymer concrete, animal feeds, mixtures dry chemicals, liquid or non-flammable adhesives, etc.

On request, the mixers can also be supplied in stainless steel.
KNIELE laboratory mixers comply with CE standards and their construction complies with the most recent EU directives in the field of machinery.
