The common characteristics of solid preparations are that compared with liquid preparations, they have good physical and chemical stability, low production and manufacturing costs, and are easy to take and carry; the preparation process generally uses a wet granulator, which is used to grind wet powder into the required particles, and can also crush blocky dry materials into the required particles. The main feature is that the screen is easy to install and disassemble, and the tightness can be adjusted appropriately. The seven-cornered drum is easy to disassemble and clean. The mechanical transmission system is completely enclosed in the body, and is equipped with a lubrication system, so the whole machine runs smoothly.

At the same time, the high-efficiency wet granulator for solid preparation production will produce some vibration during use, thereby creating a large noise and reducing the quality of the surrounding working environment. For this reason, we propose a high-efficiency wet granulator for solid preparation production. Utility Model Content
