The Ecomondo 2025 exhibition has come to a successful close, and it was an excellent experience for KISA.
Throughout the event, we had the opportunity to present our innovative recycling and material processing solutions to numerous visitors and industry professionals.
It was a week full of valuable discussions, new connections, and great inspiration.
A big thank you to our partners metcam AG, Ma-estro, and TECNOIDEA Impianti S.R.L. for sharing this journey with us at our joint booth.
Together, we are driving progress towards a more sustainable and circular industry.
KISA proudly participated for the first time in the International Mining and Resources Conference + Expo (IMARC) in Sydney — one of the world’s leading events for the mining and resources industry.
Our presence at the German Pavilion marked an important milestone, allowing us to present KISA’s innovative washing and dewatering solutions to an international audience.
Throughout the exhibition, we held numerous successful meetings with companies from around the world, discussing promising opportunities for collaboration.
KISA impressed visitors with outstanding product quality, engineering expertise, and a strong commitment to sustainability.
The highlight of the event was the opportunity to engage with companies that hold great potential for future cooperation — partnerships that will help illuminate our path forward and strengthen KISA’s international presence.
Our first participation at IMARC was a resounding success, opening new perspectives for global collaboration and long-term growth.
As of October 1, 2025, our service team has grown once again. At the same time, we have successfully integrated a new business area into our company.
In addition to our established fields of gravel and sand, mining, tunneling, and recycling, our service team now also covers the scrap industry within the recycling sector.
We are pleased to announce that, alongside the KISA brand, the RECUPERMA brand now also belongs to our company.
We warmly welcome our new colleagues and look forward to a successful collaboration!
KISA participated in the German-Chilean Forum for Mining and Mineral Resources held at the Haus der Deutschen Wirtschaft (DIHK) in Berlin on October 10th, 2025.
The forum provided an excellent opportunity to learn about the high potential of Chile in the mining and raw materials sector. Representatives from business, politics, and science gathered to discuss sustainable mining, technological innovation, and future cooperation opportunities between Germany and Chile.
We were pleased to engage in meaningful discussions with participants, which led to a constructive exchange of ideas and new insights for the international mining community.
KISA is proud to announce our participation at Ecomondo 2025, the leading event for the green and circular economy.
📍 Rimini Expo Centre – Hall C1, Booth 208-111
📅 4–7 November 2025
Ecomondo is the international platform where industries, stakeholders, policymakers, opinion leaders, and research institutions meet to shape the future of environmental strategies in Europe.
We look forward to meeting you there!
As part of the Decker Project, four conventional screening machines were replaced with four modern KISA bucket wheels.
The result: significantly lower noise and vibration levels and a noticeably reduced environmental impact.
Thanks to innovative KISA technology, operations have become much quieter and more efficient.
Noise and vibration levels have been reduced to such an extent that no further complaints from local residents have been reported.
While the previous screening machines caused considerable emissions leading to high immissions, the KISA bucket wheels now ensure quiet, clean, and sustainable operation – further proof of the reliability and quality of KISA solutions.
At KISA, we have successfully completed the production of a high-capacity dewatering bucket wheel with a remarkable diameter of 8 meters and a throughput of 500 tons per hour.
The entire system was engineered and manufactured at our facility in Kamp-Lintfort, Germany, demonstrating our commitment to delivering robust and efficient solutions tailored to demanding operational needs. The machine has been delivered to our long-term partner, PHOENIX Process Equipment, who will carry out the final assembly and commissioning on site in the United States.
This project marks an important step in our continued collaboration and reflects KISA’s expertise in designing and building customized equipment for wet processing applications on a global scale.
On June 27th, 2025, we came together at KISA to celebrate our employee summer event– a day filled with appreciation, team spirit, and a great atmosphere.
Following a short welcome speech by Mr. Meier, our Managing Director, a video was shown featuring moments from our daily work and teamwork at KISA.
Afterward, colleagues enjoyed a delicious meal before the exciting and entertaining Cornhole competition began, where the winners were awarded small prizes.
A heartfelt thank you to everyone who helped organize the event – and to our amazing team!
We are pleased to welcome Mr. Michael Silvester as a new Sales Engineer to our team starting August 1, 2025. Mr. Silvester brings many years of experience in processing technology and impresses with his expertise in international customer support, successful new customer acquisition, and active technical sales.
We wish him a great start and look forward to working together!
In the sand and gravel industry, efficiency and precision in material handling are essential. One of the most effective tools in achieving this is the dewatering bucket wheel. These machines play a key role in dewatering, fine sand recovery, and preparing materials for further processing. But how exactly do they work, and what sets the top-tier systems apart?
What Are Dewatering Bucket Wheels?
Dewatering bucket wheels are used to separate solids from water in material like sand and gravel. They are commonly found in processing plants, quarries, and on suction dredgers where raw material is delivered as a water-solids mixture.
These systems are engineered to:
- Dewater sand and gravel
- Feed suction dredgers
- Recover fine sand that would otherwise be lost
How Do They Work?
The process starts when a water-solids mixture enters the wheel body, which is already filled with water. A rotating wheel equipped with specially designed scooping elements lifts the solids from the mixture. Each scoop features sieve openings on the bottom, allowing water to drain out while retaining the material.
The rotation allows the solids to partially dry—usually during half a turn—so they reach a pumpable state. A built-in negative pressure system enhances this dewatering process. Once sufficiently dried, the material is discharged onto a conveyor belt and transported to the next stage of production.
In cases where fine sand content is high, wider troughs and feed spirals are used to slow water movement and extend sedimentation time. This prevents valuable fine material from being lost through the overflows.
KISA Dewatering Bucket Wheels — Precision and Power Combined
At KISA, we have been building dewatering systems for over 35 years. Our dewatering bucket wheels are engineered for the most demanding applications, with a strong focus on capacity, durability, and fine sand recovery.
Key specs of KISA bucket wheels:
- Wheel diameters up to 8000 mm
- Wheel widths up to 2800 mm
- Solids output up to 1500 t/h
- Handles grain sizes up to 200 mm
Whether it’s fine sand or coarse gravel, KISA’s solutions are tailored to suit various mixtures and material characteristics.
Unique Features of Our Systems
🔹 Automatic speed regulation– ensures optimal performance regardless of the mixture ratio.
🔹 Negative pressure drying– speeds up the drying process and improves energy efficiency.
🔹 Lateral charging coils– reduce fine sand loss by promoting even sedimentation and smoother water flow.
🔹 Modular construction – divided design of wheel bodies and troughs simplifies transport and assembly.
Unlike traditional catch pits, our systems introduce the material centrally. This halves the flow velocity toward each overflow, creating a more stable water surface and enhancing fine sand recovery.
In Summary
Bucket wheels may appear simple in concept, but modern systems like those built by KISA bring advanced engineering into play. Our machines are not just about removing water—they’re about maximizing output, minimizing losses, and integrating seamlessly into high-capacity operations.
If you’re in the market for a reliable, customizable dewatering solution, our team at KISA is here to help.
