A joint cooperation with Dr. Ernst-Heinrich Dressler in the field of fine and very fine screening is now official
In mid January Dr. Ernst-Heinrich Dreßler came to Haver & Boecker to sign an agreement with the company for a future cooperation in the field of fine and very fine screening.
In the late 1970s Dr. Dreßler conceptualised and designed a multiple deck screening machine that is ideal for classifying various dry materials into fine and very fine particle ranges. Since then more than more than 100 machines have gone into operation in a wide range of applications to the full satisfaction of its customers. The fine loose materials include products like quartz sand, abrasive particles and foods, for which Haver & Boecker so far has been able to offer only a few alternatives for very fine screening.
The multiple deck screening machines, which carry the name NIAGARA® M-Class within the HAVER SCREENING GROUP, are the ideal extension of the existing 5 screening systems offered by the company.
Despite their minimal space requirements, the multiple deck screening machines, depending on the design, offer very large screening surface areas. This is accomplished by stacking the screening decks horizontally over each other, which at the same time make up the frame of the linear vibrating machine. A major advantage offered by this type of screening system is the very accurate cut-size reached during screening. Another advantage of the modular design is the machine’s retroactive adaptability, e.g. to increasing material throughput. Characteristic of the multiple deck screening machines is also the extremely long operating lifetimes of the screen cloth. This is because the machine easily gets by with relatively minimal acceleration during screening, thus keeping dynamic loading down to a minimum.
The NIAGARA® M-Class multiple deck screening machines are offered in eight different sizes, where the number of decks and technical specifications vary as to the application at hand. The machines will be further developed at Haver & Boecker and optimised in close cooperation with Dr. Dreßler, thus allowing the requirements and needs of the market to be continuously fulfilled. Dr. Dreßler, with his expertise and years of experience, will also assist the HAVER SCREENING GROUP specialists in advising customers and conducting screening trials.
