[0002] Cereals are a kind of grains, which can be cooked and eaten directly, or ground into various delicacies. When grinding cereals, a grinding machine is needed. Cone milling mill is a commonly used mill, which is composed of supporting box, conical hammer, driving motor, feed cover, discharge port and other structures. When grinding, it grinds while adding materials, and the powder is fine.

[0003] The existing grinding mills still have certain defects when grinding. They need to add materials in time. The feed cover cannot store materials during grinding. Too much material in the feed cover will lead to uneven grinding. During grinding, powder will be thrown out through the feed port, causing air pollution. In view of this, we propose a cone-type grain grinding mill. Utility Model Content
