In order to study the influence of particle shape on the avalanche movement process of particles in the drum, we use the speckle visibility spectroscopy and image method to measure the intermittent avalanche movement of spherical particles and irregular particles with a diameter of 0.5 mm. The research results show that the avalanche process of spherical particles is different from that of irregular particles. Irregular particles will have two compaction phenomena, single compaction and double compaction, and the probability of occurrence of double compaction phenomenon is different under different filling degrees. The duration of single and double compaction also has a different proportional relationship with the filling degree. Additionally, it is found that the tilt angle of irregular particles is larger than that of spherical particles, and the larger the gravitational potential energy of the particle accumulation before compaction of irregular particles, the easier it is to produce double compaction.
