Abstract
The utility model relates to a high-magnesium nodularizer crushing mechanism which comprises a frame, a transmission device, a crushing bin, a gear and a rack, wherein the transmission device and the crushing bin are arranged on the frame; the gear and the rack are arranged in the crushing bin; the rack is fixed on the inner side wall of the crushing bin; the transmission device is used for driving the rack to rotate; the gear and the rack correspond to each other; an air inlet is formed in the top surface of the crushing bin; a discharging hole is formed in the bottom surface of the crushing bin and corresponds to a discharging pipe; a feeding inlet is formed in the side surface of the crushing bin. The semi-closed crushing bin in which nitrogen is introduced is designed, so that the nitrogen atmosphere with a certain concentration is formed in the crushing bin. Thus, the squeezing crushing is carried out in a low-oxygen environment. Meanwhile, the gear and the rack are designed in the crushing bin, so that a large high-magnesium nodularizer can be crushed into small granules under the squeezing of the gear and the rack. The oxidation of magnesium during a crushing process is prevented due to the adoption of the low-oxygen environment. As a result, the quality of the crushed nodularizer is improved, the working intensity of workers is lightened, and the working environment is improved.
