In a commendable move to support youth football, Kniele GmbH has decided to support the local B-youth team with new jerseys. 

Kniele GmbH, known for its innovation and commitment to the local community, has recognised that the right equipment for young athletes is of great importance. The new jerseys will give the B-youth players a fresh and professional appearance and give them a sense of pride and togetherness.

Kniele GmbH's support comes at the right time, as many local clubs struggle with limited resources and find it difficult to regularly update their equipment. The company will cover the cost of the new kits, ensuring that every player can proudly wear their club's emblem.

"We believe in the importance of sport for the development of young people and want to do our bit to help them reach their full potential. By providing new jerseys, we want to enable the B-youth football clubs to concentrate on the essentials: the game, the team spirit and the fun of the sport," says one of the managing directors Harald Kniele. 

Kniele GmbH has been a long-time supporter of the Bad Buchau sports club, the football and handball departments, as well as the local tennis club.

The Wegmann company has recently achieved a significant improvement in its production facilities. A state-of-the-art mixing plant for the production of manholes and concrete pipes was successfully installed. The plant was supplied and implemented in co-operation with the renowned Kniele GmbH, a leading company in concrete technology.

The centrepiece of this innovative plant is the KKM conical mixer, which was specially developed for this application. As part of the upgrade, the previously used pan mixer was completely removed to make room for the more efficient and powerful conical mixer solution. This decision was based on the aim of increasing production capacity and further improving the quality of the products manufactured.

The new mixing plant was installed as a complete conversion, which not only included the KKM conical mixer, but also a modern enclosure. This enclosure not only serves to protect the surrounding area from dust and noise pollution, but also offers employees a more pleasant working environment. The improved workplace situation helps employees to realise their full potential and increases productivity.

The modernisation of its production facilities not only demonstrates its pioneering spirit, but also its commitment to quality and customer satisfaction.

In December 2022, a pioneering big bag emptying station was put into operation for the company Puren in Überlingen on Lake Constance. This innovative station is revolutionising the production of insulation boards thanks to its efficiency and speed. In this blog post, we will take a closer look at the functions of the Kniele big bag emptying station and explain the benefits of this innovation for Puren. 

Low-dust emptying thanks to Kniele ring suction:
One of the highlights of our emptying station is the use of a ring extraction system. This innovative technology enables low-dust emptying of the big bag. In addition, evacuation is carried out after the big bag has been completely emptied. This ensures a clean and safe working environment.

A tubular screw conveyor is connected to the big bag emptying station. This transports the calcium carbonate to the existing mixer. This efficient transport solution ensures seamless integration into the production process.

Compact control system for optimum plant control:
The big bag emptying station from Kniele is supplied with a small, compact control unit. This enables optimum control of the entire system. This ensures simple operation and monitoring.

Acknowledgement to the company Puren:
We would like to take this opportunity to thank Puren for their trust and co-operation. We are proud that our big bag emptying station can make a contribution to increasing efficiency and improving production processes. Kniele wishes Puren continued success.

Conclusion:
The big bag emptying station from Kniele is a pioneering innovation for Puren. With its efficient emptying, low-dust ring extraction and seamless integration into the production process, it helps to optimise the manufacture of insulation boards. The compact control system makes it easy to operate and monitor the system. Kniele is proud to be part of Puren's success and looks forward to further joint projects.

Wetcast products are also becoming increasingly popular in Germany. Natural-like surface structures, noble color nuances and high durability are properties that make the cast concrete products attractive.

With the presentation "Mixing and concrete batching technology for wetcast production" KNIELE will show the strengths of the Kniele conical mixer KKM and the specially developed batching systems for wetcast concretes.

Kniele has once again demonstrated its expertise by supplying a state-of-the-art mixing plant for ready-mixed concrete and a precast plant to the renowned company Reisch in Bad Saulgau. This collaboration, just 10 kilometres away from Kniele's headquarters in Bad Buchau, strengthens the cohesion of the Upper Swabian companies. In this blog post, we will take a closer look at the core components of this mixing plant and explain the benefits for the companies involved. 

The Kniele KKM conical mixer: a tried and tested component:
The KKM 2250/3375 is once again the core component of this mixing plant. With an impressive hardened concrete output of 2.25 m³, it ensures efficient and precise mixing of the raw materials. The in-line silo plant with 9 chambers, made of concrete and sunk into the ground, is equipped with dosing gates and vibrating chutes to enable precise dosing of the raw materials. A weighing belt almost 40 metres long ensures the exact weighing of the raw materials such as sand, gravel and other aggregates. A feeder lift with fall protection ensures smooth transport of the materials from the cellar to the mixer.

Frequency inverter and automatic high-pressure cleaning system for optimum control and maximum cleanliness:
The Kniele conical mixer has frequency inverters that enable infinitely variable control of the two agitators. This allows the mixture to be optimally adjusted. An automatic high-pressure cleaning system is also integrated to ensure efficient cleaning of the mixer.

Precise dosing with cement weigher, water weigher and admixture weigher:
To ensure precise dosing of the raw materials, the mixing plant is equipped with a cement weigher, a water weigher and an admixture weigher. These components ensure the precise addition of the required materials and admixtures to achieve the desired quality of the concrete.

Further equipment features for efficient plant operation:
The Kniele mixing plant for Reisch also includes 4 cement silos with the option of adding a further silo. In addition, a heating system was installed to ensure smooth operation even at low temperatures. A recycling plant and a water treatment system were also integrated to enable economical utilisation of the plant. 

The mixing plant from Kniele for Reisch is another example of the company's outstanding engineering skills. With the proven Kniele KKM conical mixer and the numerous components installed, Reisch is not only increasing its production capacities, but also improving the quality of its concrete parts many times over. We would like to thank you for the trust you have placed in us as the main supplier to one of the most renowned family businesses in the Upper Swabia region and wish you every success for the future.

The world is becoming faster and more versatile. So are the demands on manufacturers of modern materials. For our customer MIG - Material Innovative Gesellschaft in Salzkotten, North Rhine-Westphalia, we installed a new dry mixing plant for a wide range of building materials and chemical additives at the beginning of 2022.

High product flexibility was the focus of this plant.
Depending on the quantity, the raw materials are delivered either in big bags, in sacks or by silo vehicle. A total of 3 big bag emptying stations, 4 silos and 1 bag emptier are connected upstream of the KNIELE cone mixer. In addition, small components can be fed by hand. The core of the dry mixing plant is a KKM 1000/1500 with 1m³ output. After mixing, the ready-mixed material can either be filled into a big bag, transported into a storage silo or packed into bags in a bagging plant. Truck loading has also been realised.

We wish our customer much success with the new plant and maximum flexibility in his products!

Innovative products for construction not only make physical work easier, but also reduces construction time. With the commissioning of the new mixing plant from KNIELE in combination with a bagging plant from Haver&Boecker, our Austrian customer will be able to produce light plasters as bagged goods in the future.

The cement is conveyed from the silo, which is located outside the hall, into the KNIELE cone mixer KKM via a cement screw. The heart of the plant has an output of up to 375 kg per batch. Styrofoam is fed into the mixer via a pipe conveyor system and mixed with cement and a binding agent.
The big challenge here is to produce a homogeneous mixture of the "heavy" cement and the extremely light polystyrene balls. However, the KKM masters this task within a very short time, whereas other mixers would need several minutes or there would be no mixing at all!
Below the mixer, the material is stored in a pre-silo to continuously feed the Haver&Boecker packaging plant below.

After a big bag emptying station with bag feeding and pipe conveying system was installed for the company AMG Graphit Kropfmühl already at the beginning of 2021, the second construction phase was put into operation exactly 14 months later.

Graphit Kropfmühl is a manufacturer of all products made of graphite, such as powder-metallurgical parts for the automotive industry, carbon brushes for electric motors, insulating materials for the construction industry and many other materials.

At the Hauzenberg site, two more big-bag discharge stations with negative weighing and two bag feed hoppers on a platform have now been installed. The graphite powder is then conveyed into two conical mixers, dosed and mixed.

On behalf of KNIELE, we would like to thank Graphit AMG for the excellent cooperation.

The company CBS Home in Deißlingen produces precast concrete parts according to the CBS system (Compound Building System). Here, the supporting structure, which consists of folded galvanised sheets, is also the formwork for the prefabricated parts - innovative and sustainable at the same time.
The filigree lightweight steel structure is completely encased and filled by the foamed lightweight concrete based on expanded clay.

The heart of the plant is a KNIELE conical mixer KKM 2250/3375 with an output of 2.25m³. The matching feeding system was also supplied by KNIELE. 6 aggregate silos feed a mobile scale via dosing belts. The scale in turn feeds the KNIELE material lift, which transports the mix into the KKM. The feeder lift is equipped with a special fall protection.

Many thanks for the many good discussions and the great interest in our Kniele cone mixers and big bag stations.

We are already looking forward to the next FAKUMA in 2023!

We are currently assembling a new concrete mixing plant for ready-mix concrete in Bad Saulgau for one of the largest construction companies in the south of Germany, the Georg Reisch GmbH & Co. KG company.
The concrete structure is being built by the developer himself, with the mixing plant technology being supplied by KNIELE.
The entire weighing system with batching belts and vibrating feeders have already been installed. Still at the end of May the KNIELE cone mixer KKM with a concrete output of 2250 liters was installed. The next step will be the feeding system of the mixer as well as the installation of the cement silos.
We will keep you up to date...

With a total length of over 25m, we have set up the largest machine platform in the southwest!
The new mixing plant will later be used for the production of special aerated concrete hybrid construction elements. The heart of the plant is a KNIELE cone mixer KKM 2250/3375 with 2250 litres output.

Last year we didn't just invest in a new logo for Kniele GmbH - a comprehensive brand marketing and CI concept was developed,  and gradually implemented. We were ready to present our new CI to the public at BAUMA 2019.

The fair design, designed down to the last detail, and our new product guide left a lasting impression and our customers and trade fair visitors give us a positive feedback. Now it is time to let the production and administration shine with this new design on site in Bad Buchau.

It starts with the administration building.
