With our Dust Free Sugar Grinder, the materials are sucked into the milling chamber under the negative pressure, and then are impacted, cut and ground under the effect of the large air-flow between the blade and module. The process of the crushing is free of dust because of the dust removal system. The fine dust will be sucked into chamber. The capacity can reach 1000-1500kgs/hour, and grinding fineness is between 80~10um.
