In waste recycling processes, the development of comminution technologies is one of the main actions to improve the
quality of recycled products. This involves a rise in fine particles production, which could have some effects on
explosibility properties of materials. This paper reports the results of experiments done to examine the explosibility of
the fine particles resulting from waste recycling process. Tests have been conducted for the products derived from
milling processes operated in different operative conditions. In particular, the comminution tests have been executed
varying the milling temperature by refrigerant agents. The materials utilized in explosibility tests were different
typologies of plastics coming from waste products (PET, ABS and PP), characterized by size lower than 1 mm. The
results of explosibility tests, carried out by mean of a Hartmann Apparatus, have been compared with the data derived
from image analysis procedure aimed to measure the morphological characteristics of particles. For each typology of
material, the propensity to explode appears to be correlated not only to particle size, but also to morphological properties,
linked to the operative condition of the milling process.
