The grinding of ultrafine talcum powder and its application in a polypropylene (PP) matrix were investigated. Ultrafine talcum powder was prepared by adjusting the grinding parameters of the physical milling process. The talcum powder exhibited polymodal distribution. The layered morphology of talcum particles in a horizontal sand mill was rarely damaged or destroyed. PPtalcum ...

Results The experimental investigation was conducted (Alfano et al., 1990, 1992, 1993) with the jet :mill depicted in Fig. 1 on three different minerals, baryte, kaolin and talc. The baryte, a gravity concentrate supplied by an industrial plant in Sardinia assayed % BaS04, % Si02 and % CaC03 with a degree of whiteness of 97.

grinders are jet mill and agitated mills such as stirred media mills [1]. Jet mill first developed for producing particles diameter less than 100 microns and having a high degree of purity. Jet mills are extensively used in the pharmaceutical industry due to their ability to produce fine particles without the wear of mechanical parts [3].

Gommeren [1], who studied polymer grinding in a spiral jet mill and also in a 200 and 400 AFG opposed air jet mills, may be quoted. His interest was mainly in modeling the overall grinding classification process in a spiral jet mill. Berthiaux and Dodds [2] modeled the overall grindingclassification process of hydrargillite in an Alpine 100

This investigation reviews the effects/influences of the main jet milling parameters, with special focus on lowdensity products. The aim was to transfer all positive results into a special mill/plant design for such products. Although the jet mill principle with opposed jets was invented over 140 years ago, 1 its evolution is not over yet, and ...

Jet milling is suitable for any material hardness value: from Mohs' hardness 1 (talc) to Mohs' hardness 10 (diamonds). Principle of operation During expansion, the energy contained in the compressed gas in the form of heat is converted to kinetic energy. The speed of sound is initially a natural limit for the exit velocity.
