Abstract:Two kinds of tooth type pulverizing cutter heads are designed based on the principle of superfine pulverization technology, and two kinds of pulverizing knives are analyzed using Fluent simulation software at the speeds of 6 000 r/min, 9 000 r/min and 12 000 r/min. The variation of pressure and speed inside the head was studied. Then the pulverization effect of the two cutter heads was verified by the material pulverization experiment. At the same time, the energy consumption of the two cutter heads was compared and analyzed. Results: The central structure was a four-blade blade tooth-crushing cutter head. The time spent smashing 50 g of soybean was about 2 min. The average particle size of soybean after pulverization is about 4 μm, and the energy consumption ratio was consumed. The center structure had less tip consumption for the three impellers. The energy consumption for crushing for 5 min at 6 000 r/min, 9 000 r/min, 12 000 r/min were approximately 0.007 25 kW·h, 0.022 49 kW·h, 0.059 43. kW·h, respectively, which had good practical application significance.
