Analysis of the structure and usage regulations of the two-color tablet press1

Two-color tablet press is to grind two different materials into one tablet. The two materials are separated from each other and have different colors. The shrinkage of the two-color tablet is mainly based on the design and modification of the lower slide rail. 2 fillings and a slice. The key conditions for the two-color tablet press to suppress the two-color tablet process are: (1) The content of the two materials on the same tablet does not meet the requirements. This is mainly because the filling adjustment system is not adjusted, and the content of one material can be adjusted first. Then adjust the content of the other material; (2) The two materials of the extruded tablet have a split state, and the strength is uneven. One material is harder and the other is softer. The main reasons are: 1) the material Reasons, density, drying humidity, poor adjustment of the uniformity of the two materials, and then adjust the materials before suppression; 2) Improper adjustment of the pressure of the two materials. The principle of producing a two-color film is the second filling, once, if the pressure is not adjusted after the first filling, the strength of the second half will become hard or loose. After the second fill, the pressure is set for the completed tablet, so the pressure adjustment determines the level of tablet formation and fusion. Two-color tablet presses often require two vacuum cleaners, which can separate the two materials for powder absorption and recovery. Provided the user specifies the composition of the two materials, the tablet press can be equipped to remove tablets from each of the materials and measure them to determine their content
