Abstract:
A tableting machine is used to form powders into tablets. It is well known that the quality of tablets formed by tableting machines varies greatly depending on the compression conditions, such as compression velocity and compressive force. It is of industrial importance to clarify how compression conditions affect the properties of the formed tablets. In this research, we manufactured a tableting machine with an upper and lower pestle that can be arbitrarily operated, and the aim of this research is to clarify the relationship between the tableting conditions and the property of the formed tablets. In this experiment, we change the driving pestle as the tableting condition, measure the formed tablet hardness, and discuss the relationship between them.
