attrition, impact or shearing. Jet mills, ball mills and highpressure homogenization are commonly used for mechanical micronization of drugs and dry milling in a fluid energy mill (jet mill) is the most preferred micronization technique [3].

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

Media Milling, Dry and Wet. Ball milling, or media milling, uses collision and shear forces to grind down material, whether wet or dry. A ball mill can operate at either high or lowenergy outputs, and material characteristics can span a wide range. Adjustable variables include ball types and sizes, speeds, material mass in slurry, and more.

Cellulose materials were ballmilled with an ITO LP1 Planetary pot mill. 80 mL of jar with the three different diameters of zirconia ball (10, 5, and 2 mm) was used, in which the ball to material weight ratio (BMR) was 12:1 and the weight ratio of the balls with 10, 5, and 2 mm diameters was 5:4:3. In the preliminary experiments, it is found ...
This micronization occurs with mills having two counterrotating parallel blades, which, with a thrust of 2500 km/h and particular aerodynamics, create two counterrotating airflows [46]. This ZC ...
Research background: By tailoring dietary fibre's structural and physicochemical properties, their functionality and applicability can be remarkably increased. One of the approaches used in this respect is fibre particle size reduction.

Micronization is most often used to describe processes that reduce particle size by using fluid energy, such as a jet mill, rather than by mechanical means. Mechanical particlesize reduction using a bead mill, however, can also be used to obtain micrometer and nanometersized particles. Jet milling. Jet milling does not use mechanical ...
Media milling can be considered a modernized version of the ball mill (Fig. 3).
