Haver & Boecker Australia have launched its next generation Niagrara M-Class screening machine for classifying dry bulk materials.
Following a complete overhaul of the original M-Class, the next-gen model optimises the features of its predecessor to create an even more efficient and high-performance multiple deck screening machine.
The company’s head of mineral processing technology, Steffen Silge, said the system delivers accurate cut size for the classification of up to 11 different product fractions with only one point of transfer for each fraction, making it a suitable solution when it comes to fine and ultrafine particle ranges.
The M-Class features include the extension of the g-force range from 2g to 4.5g, preventing screen cloth clogging; the ability to adjust the frequency and amplitude depending on the task at hand; and a new isolation frame, ensuring dynamic loads are reduced to a minimum and vibrations are minimised.
Ease-of-maintenance is also improved by a new type of transversal tensioning. The double screen-frame, which exists in previous models, is no longer needed, so the additional cost for a frame tensioning service is redundant. Replacing standard screen cloth can now be done more rapidly and with greater ease.
In its modular design, the multiple deck screening machine can have a vast screen surface in a space-saving design. The individual screen frames are horizontally stacked above each other and serve to act as the frame of the machine. The ability to later adapt the machine, to increase material throughput for example, is another advantage of its modular design.
The machine is offered in two sizes, 1000mm x 2800mm and 2000mm x 2800mm, with variations in the number of screen decks and technical specifications.
