With a seventy-year history in designing, manufacturing, operating and service of pelletizing equipment, Haver & Boecker Niagara has established itself as a leading specialist in the production of the innovative SCARABAEUS© 7500. Sustainability, maximum efficiency and improved product quality are the main reasons for our customer from Ukraine, to place its trust in our team by ordering in total 15 of our pelletizing discs, 7 of which are about to go into production due to the currently signed contract.
According to our strategy, development and implementation of the most efficient technologies for mining and processing, our company cooperates in Ukraine with the engineering company NPO RAKURS LLC.
In this case, the SCARABAEUS© 7500 is able to generate a tight pellet distribution, especially in the high-grade fraction of 10 to 12.5 mm, in total up to 150 tph. The SCARABAEUS© 7500 has no analogues in the world: its peculiarity lies in a variable board height to obtain narrow grades of pellets with increased strength characteristics, while reaching the capacity up to 150 t/h. In addition, the pelletizing disc is equipped with a pellet monitoring system for the granulometric analysis of the pellets and an automatic control system. Thanks to the supplied set of equipment, the SCARABAEUS© 7500 operates in a fully automatic mode and reproduces the pellet class set by the company’s technologists. The tight pellet size distribution aids in the direct reduction process, even with innovative hydrogen process, which improve sustainability by reducing CO2 emissions.
The principle of operation of the device is simple: in an inclined, cylindrical rotating disc, by presence of enough liquid pellets are formed from a powdery material. The raw material is brought to the condition by automatically setting the optimal operating parameters by changing the angle of inclination, rotation speed, and also by adjusting the height of the side of the disc, which turned out to be a decisive factor in fine-tuning the process. This is how we are providing the development of exclusive solutions and ensure our customers the highest quality for the processing of iron ore.
“In general, the SCARABAEUS© pelletizing disc is available in a variety of sizes ranging from 1.6 feet to 24.6 feet (0.500 mm to 7.500 mm). Our pelletizing discs are in use in different applications, e.g. recycling of steelworks remnants, mineral fertilizers, R&D centers, building materials, Iron Ores Pelletizing and Sinter optimization and even future-oriented applications in the energy sector. Anyhow, most impressive application regarding the size is without doubt Iron Ore Pelletizing with multiple lines of pelletizing discs, each line with up to 10 discs, is fascinating”, mentioned Dr. Jan Lampke, Haver & Boecker Niagara Technology Unit Manager.
With its production of DR-pellets, the SCARABAEUS© 7500 also makes its place among the innovative technologies for Green Steel: “It is the direct iron ore reduction process, enabled by those uniform size pellets, which finally leads to the tremendous reduction in greenhouse gases. This innovative pellet based solution avoids the traditional blast furnace route and, hence, the energy intensive smelting of the ore and ensures the production of 97% pure iron at the end. This is such a great contribution to protect our climate through technology innovation” (Prof. Holger Lieberwirth, Director of Institute of Mineral Processing Machines, Technical University Bergakademie Freiberg). Such success would not be possible without conducting iron ore tests in the Associated-Institute of TU Bergakademie Freiberg – HAVER ENGINEERING GmbH and proving the possibility of achieving the desired parameters with the main aim – to create added value for our customers through sustainable technically sound solutions, perfect quality, guaranteed reliability and absolute flexibility!
All in all, the operation with the SCARABAEUS© 7500 offers:
– Sustainable and efficient production of iron ore pellets
– Specification deeds for the processes of direct reduction
– Energy-savings to up to 5% by reduced recycling rate
– Improved product quality
– Increased product output
– Reduced CO2-emissions
Thanks to the close work of Haver & Boecker Niagara and NPO RAKURS LLC, we are proudly part of this big exciting project with our Ukrainian customer:
“With this extremely important step, we continue our endeavor to become the most influential manufacturer of pelletizing technologies within the iron ore processing industry,” said Dr. Metodi Zlatev, Haver & Boecker Niagara Head of Sales.
Believing that today’s reality shaped by the influence of environmental, economic and political trends, can be separated from the term impossible, our team is proud to be part of the iron ore processing industry and to continue introducing new modern and sustainable solutions.
Our global network of experience allows us to solve the most unique problems.
