Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to an adjustable grain grinding mill. Background Technique

[0002] Grains are the seeds of herbaceous plants, in granular form, with different sizes, shapes and colors, rich in nutrients such as carbohydrates, proteins, dietary fiber, vitamins and minerals. They are an important source of food for humans, occupy an important position in agricultural production and have important economic value, and are also of great significance to the sustainable development of agriculture. A grinding machine is used to grind some dry grains such as coffee beans and rice into powder to meet the usage needs of users;

[0003] When grinding grains, the materials are usually ground by the rotation between grinding discs. However, the grinding discs of the existing grinding disc machines are usually fixed on the surface of the transmission structure by bolts, resulting in difficulty in adjusting between the grinding rollers. Furthermore, when grinding different grains, it is difficult to grind them into the required finished products, with limitations in movement. And there are impurities in some grains, and some impurities will also be crushed and mixed with the grains during grinding, resulting in a decline in the quality of the ground grains. For this reason, we propose an adjustable grain grinding mill. Content of the Utility Model
