Grinding of talc particulates by a high-speed rotor

2001-1-1  CONCLUSIONS The grinding of talc particulates was conducted by a high-speed rotor mixer without media (beads) under atmospheric conditions to investigate the performance of the mixer. The motion of the particulates in the mixer was simulated by the PEM to calculate the force acting on them.

A Model of Batch Grinding of Talc Powders

Grinding of talc powders has been studied both theoretically and experimentally. The specific rates of breakage of talc powders were measured based on the first-order breakage kinetics model and the cumulative breakage distribution parameters of talc powders were measured from primary breakage products. Based on the measurement results, the specific rate of breakage and cumulative breakage ...

Aspects of Talc Grinding in the Presence of Sodium

2021-3-27  The optimum conditions for talc grinding are similar in the absence or presence of SDS in terms of factors under study, except for solids%. The vital role of SDS, as a grinding aid, is the production of particles with the same fineness or even finer at higher solids % which leads to an increase in the mill throughput.

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

Talc Grinding - 911metallurgist

2016-5-24  As the grinding progresses, the inefficiency increases: the most active grinding is done in the first hour, for the fine talc gradually cushions the impact of the pebbles and little grinding is done at the end. In one mill 5000 lb. of pebbles are used to one ton of talc in a mill revolving for 5 to 7 hr. at 22 r.p.m.

Grinding of talc particulates by a high-speed rotor

2001-1-1  Talc particulates were ground by a high-speed rotor mixer without grinding media (beads) under atmospheric condition in order to evaluate the performance of the mixer. The median diameter of the ground sample decreases with an increase in both rotational speeds of the rotor and the vessel, and with a decrease in the clearance in the working space.
