Process control and optimization is a critical aspect of process analytical technology (PAT), quality by design (QbD), and the implementation of continuous manufacturing procedures. While process control and optimization techniques have been utilized in other manufacturing industries for decades, the pharmaceutical industry has only recently begun to adopt these procedures. Micronization ...

A Kinetic Study of Micronization Grinding of Dry Mica in a ... Hindawi

This paper presents results of the research of micronization grinding of dry mica in a planetary ball mill. Investigation was conducted in order to improve the quality and to obtain clearly defined properties and characteristics of mica powder. The micronization grinding of dry mica was performed in four time periods: 30, 60, 120, and 360 minutes. The micronized powder was investigated by ...

PDF Micronization of a Soft Material: AirJet and MicroBall Milling

The yield achieved with the microball mill was 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.

Ball milling: a green technology for the preparation and ...

The effect of ball mill on the morphological and structural features of cellulose has been described by Okajima and coworkers. 20 They treated microcrystalline cellulose derived from cotton linters in a planetary ball mill at 200 rpm for 48 hours in dry and wet conditions with three solvents (water, toluene, 1butanol). They observed that ...

PDF Micronization of a Soft Material: AirJet and MicroBall Milling

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

Granulometric fractionation and micronization: A process for increasing ...

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.
