Talc Grinding - 911metallurgist

2016-5-24  Where dry grinding is used, some system of air separation is the cheapest and most efficient method of grading very finely ground talc. It has not been proved that fibrous talc from New York State, which contains fibers, flakes, and rounded grains, can be successfully separated by air, for, without fairly close sizing, large thin flakes settle in air at the same rate as small rounded grains.

1994-6-1  The grinding produces a progressive increase of the accessible sites for NI-I4+ and Naions. Okuda et al. (1969) reported that the CEC of talc increased from 0.4 meq/100 g to 1.5 meq/100 g when the surface is incremented up to 20 m2/g by grinding; in this study, the mineral remained unchanged with respect to its crystallinity (i.e. no amorphization).

Influence of dry grinding on talc and kaolinite

2005-8-1  One minute grinding has also a minor effect on the specific surface area calculated from the particle geometry, but significantly increases the edge area of the ground talc from 13.5% before grinding to 21% after 1 min grinding. The edge area increase is likely to be beneficial for better dispersion of talc in aqueous systems.

THERMAL BEHAVIOR OF GROUND TALC MINERAL

2008-12-9  Talc is used as raw material in theproduction of ceramics, as a filler in paperproduction and in many other industrialapplications. Grinding has been used tomake suitable size of particles in order tocontrol the reactivity of raw materials. It isknown that dry grinding leads to randomdelamination of the silicate layers, to a strongstructural alteration with important particlesize reduction, to an increase in surfacearea. It was demonstrated by variousauthors[2-5] that at the beginning of grindingof talc the original stacking layers weredelaminated resulting in a decrease ofparticle size, in an increase of surface area aswell as in an increase of structure disorder;by increasing the grinding time of the talcmineral anamorphous material can beobtained. It was observed [1,6] that grindingof the talc

Ultrafine grinding is required in most industrial applications of talc. In this work, a planetary mill was used to produce a d50 product of less than 5 μm. The effects of grinding time, media size, mill filling, rotational speed, and media-to-powder ratio, as the main grinding parameters, were initially investigated by the one-variable-at-a-time strategy.
