Restitution Coefficient Determination of 3D Printed Materials

In the presented paper, attention is paid to the need for the grinding of different materials. The ball mills are discussed as a method for grinding. The processes in the ball mills are investigated. The advantages of using 3D printed materials for investigation of the separation angle (shoulder angle) and angle of incidence (toe angle) are discussed. The need for the determination of coefficient of restitution is considered. The coefficient of restitution of 3D printed materials is terminated in a laboratory by using a high-speed camera. 3D printed spheres are used, which are dropped to 3D printed plates. The properties of the 3D printed spheres are placed on a table. The experimental setup is explained. The coefficient of restitution is measured by determining the height of the drop and the height of the bounce. A table is made where the data from the different materials are recorded. For each data, three experiments were performed. Future steps are discussed.
