The pellet printing machine has been widely used in pellet production processes, and it often generates vibrations. The aim of this study is to identify the characteristics of mechanical vibrations that occur in a vertical type pellet printing machine. Additionally, the study aims to determine the mechanical vibrations that occur in the pellet printing machine. The research results showed that the mechanical vibrations in the vertical type pellet printing machine with a roller drive system and no load on the motor mount resulted in a velocity of 23 mm/s, displacement of 0.346 mm, and acceleration of 48 m/s2. For the output product section, the velocity was 28 mm/s, displacement was 0.934 mm, and acceleration was 97 m/s2, classified as high. The roller section had a velocity of 33 mm/s, displacement of 0.9 mm, and acceleration of 183 m/s2, classified as high. The frame section had a velocity of 48 mm/s, displacement of 0.4 mm, and acceleration of 48 m/s2, classified as moderate. The vibration measurements were conducted for 1 minute. Furthermore, when the pellet printing machine with a roller drive system was loaded on the motor mount, the velocity was 21 mm/s, displacement was 0.25 mm, and acceleration was 0.30 m/s2, classified as low. For the output product section, the velocity was 14 mm/s, displacement was 0.363 mm, and acceleration was 0.48 m/s2. The roller section had a velocity of 8 mm/s, displacement of 0.277 mm, and acceleration of 0.66 m/s2, classified as moderate. The frame section had a velocity of 21 mm/s, displacement of 0.75 mm, and acceleration of 46 m/s2.
