Abstract

The invention discloses a grinder for coarsely grinding grains. The grinder comprises a main case, a feed hole, a discharge hole, two rotors transversely arranged in parallel, and a power device for driving the two rotors to inward rotate in opposite directions, wherein the two rotors are covered by the main case. The grinder is characterized in that a plurality of abrasive wheels are fixedly installed on each rotor, two ends of each abrasive wheel are circular truncated cones and the abrasive wheel is in a structure with thick middle and two thin ends, a plurality of spinous bulges are distributed on the side of the circular truncated cone of each abrasive wheel, the abrasive wheels on the two rotors are engaged and a gap is formed between the abrasive wheels. Since the working surface of the grinder is a curved surface, the working surface is increased in comparison with a pair-roller grinder, the yield is increased, and the grinding efficiency is greatly improved; the plurality of spinous bulges on the abrasive wheel can play the roles of puncturing and tearing on the material during grinding, so that the ground material is less in powder, the test shows that little ground powdery material is generated, and the grinding cannot be influenced by the water content.
