[0002] Granule mixer is a machine that evenly mixes two or more granules. It is widely used in chemical, pharmaceutical, food and agricultural fields, and is an indispensable equipment in modern production. For example, in the pharmaceutical industry, it can be used for drug mixing and processing; in the food industry, it can be used for mixing flour, seasonings, and food additives.

[0003] The working principle of a granule mixer is usually to mix different granules together by stirring, flipping, and impacting. Among them, stirring is the main mixing method. The granules are continuously flipped and impacted by the stirring device inside the equipment, so that different granules are dispersed with each other, and gradually achieve a uniform mixing effect during the stirring process. According to different stirring methods, granule mixers can be divided into many types, such as spiral stirring mixers, vertical stirring mixers, forced stirring mixers, etc. Each type of mixer has its specific application scenarios and advantages. The granule mixer is an important industrial equipment and is very necessary for the manufacturing industry. Choosing the right type and technical parameters of the mixer, as well as the correct method of use, can ensure the smooth progress of the mixing process and the high quality of the final product.

[0004] At present, in the pharmaceutical, chemical, food and other industries, there are many types of granule mixing equipment, but there are generally problems such as low mixing efficiency and uneven mixing; traditional mixing equipment such as spiral stirring mixers, vertical stirring mixers, etc., mainly use mechanical stirring or gravity to mix granules, but due to the different properties of granules, it is often difficult to achieve the ideal mixing effect. For this reason, we provide a granule mixer. Utility Model Content
