The lifted material is thrown between the grinding roll and the grinding ring. The grinding powder is blown by the air flow of the blower to the classifier above the main machine for sieving. If the fineness is too coarse, it will fall into the main machine for re-grinding. The fineness qualified powder will be collected by the collector to become the finished product.

Ultrafine mill can adjust the fineness of finished products arbitrarily between 80 and 400 meshes, equipped with pulse dust collector, can achieve 99% efficiency of dust collection, and all positive pressure parts of the main engine have been sealed to achieve dust-free processing workshop, not only that, the mill maintenance is also convenient, the use of sealed structure design, replacement of the ring does not need to dismantle the roller device, so. The whole machine is easier to maintain and more efficient.
