This paper presents an original method for the micronization of coal particles in a hydrojet mill, which allows effective comminuting of coal in the pressure range of 100250 MPa, at a variable water flow rate of dm3/s. The discussed highpressure water jet mill (HPWJM) allows the comminution of standard fines, with a grain size up to 2 mm, and at a relatively high comminuting ...

This research used two different micronization techniques. Cryomilling is a ball mill micronization process that is carried out at a low temperature (RETSCH, 2021). The grinding jar is cooled to ca. −196°C by liquid nitrogen supplied continuously before and during the micronization (Junghare et al., 2017; RETSCH, 2021).
