Design and Analysis of a Hammer Mill Machine in High-Efficacy Recycle Process

This paper proposes a three-dimensional model of the hammer mill for high-efficacy recycle process. It has been established with modeling software (SolidWorks) to solve the inconvenience of the testing with a real machine by imported into Simulink. According to various types of wastes creating in huge amounts by every consumption around the word, an effective hammer mill machine is strongly required. The machine should be able to mill all types of wastes including soft (food waste) and hard materials (construction and demolition waste). The significant factors of the modeling of a hammer mill machine are relied on its blades. Therefore, we introduce the calculation of force applying to the blades, as well as, the evaluation of materials are used for making the blades (Stainless steel and Titanium). The evaluation of the force according to the blade materials are conducted by the simulation of the hammer mill model used for corn and brisk. The experimental results show that the proposed force applying to the blades made of Titanium are able to mill both of corn and brisk more efficiently than stainless steel blades do considering to the following parameters: normal stress, static stain, static displacement, and factor of safety (FOS).
