Multiple cut-points

HAVER NIAGARA M-Class®  – the HAVER & BOECKER solution


In mineral processing, the NIAGARA M-Class® takes up an intermediate position between a linear vibrating screen of conventional design and direct screen excitation. Thus, the NIAGARA M-Class® seamlessly fits into the HAVER fine-screening portfolio next to the proven NIAGARA Flat-Line® and Fine-Line® screening machines. The NIAGARA M-Class® is well suited for classifying and oversize particle removal, and has some outstanding references in the quartz sand industry and underground salt mining.

To minimize screen blinding, bouncing balls are used in combination with increased rotary speeds.
