The trough mixer is widely used for material mixing in industries such as pharmaceuticals, food, chemicals, and electronics. Especially suitable for mixing materials with high uniformity requirements and large differences in specific gravity. The mixing cylinder participates in swinging during transmission, allowing the materials in the cylinder to be fully mixed. The discharge port of the mixing drum deviates from the centerline of the cylindrical part of the mixing drum, making the machine have the characteristics of rapid mixing, large mixing volume, and convenient discharge. It is reported that the trough mixer is used to mix powdered or paste like materials, so as to mix different materials evenly. It is a horizontal groove shaped single blade mixing, and the stirring blade is a through shaft type, which is easy to clean. All contact areas with objects are made of stainless steel, which has good corrosion resistance. The mixing tank can automatically flip and pour materials. It is understood that the medical trough mixer is a new product, which is a new type of mixing and blending equipment independently developed by technicians based on the absorption of excellent domestic and foreign technologies. With its excellent structure, reasonable design concept, and fine processing technology, this equipment is widely used in various industries such as plastics, rubber, pharmaceuticals, dyes, food, and daily chemical industry for the mixing, stirring, drying, coloring, and other processes of various materials. The medical trough mixer is an internal horizontal trough single slurry mixer used in the pharmaceutical industry to mix paste like materials, ensuring uniform mixing of different materials without causing material dissolution, volatilization, or deterioration during the mixing process. Before use, an air run test should be conducted. Before the test, the firmness of all connecting parts of the machine, the amount of lubricating oil in the reducer, and the integrity of the electrical equipment should be checked. Then, the main switch should be closed, the power should be turned on, and the air run test should be carried out. Expert reminder: Management personnel must be familiar with the technical performance, internal structure, and operating principles of the control structure of this machine. During operation, it is not allowed to leave the work site to prevent mechanical damage caused by malfunctions, in order to ensure safe production.
