particles, a single type of Talc mined in France has been used: Talc 00 (Luzenac, France), micronized with a 100 AFG fluidized bed air jet mill. This Talc will be called Talc 9000 (in reference to the micronization conditions). The particle size (d50≈7 μm) of this Talc has been determined using a Malvern Mastersizer 2000 (dry dispersion in ...

The size reduction of silica was intensive as the jet mill is energy intensive. Abrasive and destructive breakage mechanisms took place varying according to the operating conditions of the jet mill. The minimum particle size obtained was 3.15 μm with a span value of 1.30. The circularity value of the ground silica ranged from 1.29 to 2.02.

1. Introduction. Air jet milling, or more correctly fluid energy milling, uses high velocity jets of gas to impart energy to particles for size reduction. Albus [1] gives a brief history of air jet mills. The first versions, developed in the late 19th century, used a jet of compressed air to project solids against a target.
