The yield achieved with the microball mill was 100% but was ~80% for the airjet mill, which reduced the size of Pluronic® F68 from 70 μm to sizes ranging between 2339 μm median diameters.
The micronization of F1 and F2 fractions using a ball milling (300 r min −1 /5 h) reduced the average particle size by 20 times yielding F1AG ( μm) and F2AG ( μm). Micronization caused a redistribution of fiber fractions (from insoluble to soluble), decreased lignin content and changed granule morphology.
There are several types of mills available for particle size reduction; but, currently, only the airjet fluid energy mill and ballmill are commonly used to reduce the particle size to 5 μm or less in dry conditions (11). Furthermore, both are available on a small bench top scale, ideal for laboratory use, and have the advantages of high milling

Micronization is the process of reducing the average diameter of a solid material's particles. Traditional techniques for micronization focus on mechanical means, such as milling and techniques make use of the properties of supercritical fluids and manipulate the principles of solubility.. The term micronization usually refers to the reduction of average particle diameters to ...
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).
interchangeability make it easy for a single mill to produce a variety of results [4]. Some of the common techniques for size reduction are listed as follows: Multi Mill The Multi mill working principle involves a variable force rotate blades having both knife and sharp edges with validated screen size to reduce particle in a controlled manner.
