Kinetics of dry grinding of industrial minerals: calcite and barite
(ELSEVIER SCIENCE BV, 2002)
This paper presents the kinetics study of dry ball milling of calcite and barite minerals. The experimental mill used was a laboratory size of 209 nun diameter, 175 mm length, providing a total 3 mill volume of 6001 Cm, ...
Relationship between the breakage and wetting characteristics of lignite
(NATL INST SCIENCE COMMUNICATION, 2002)
This paper reports the findings of an investigation of the breakage values of lignite to relate the wettability properties. The breakage values, obtained from grinding, are the specific rates of breakage (S-i) and the gamma ...
Kinetics of wet versus dry grinding of lignite by a porcelain mill
(NATL INST SCIENCE COMMUNICATION-NISCAIR, 2002)
The kinetics of dry versus wet grinding of several feed size fractions of lignite in a laboratory size porcelain mill are reported here using feed fractions prepared to 600+425, -425+300 and -300+212 mum mono-sizes. The ...
Determination of the breakage and wetting parameters of calcite and their correlations
(WILEY-V C H VERLAG GMBH, 2002)
This paper presents the breakage and wetting parameters of calcite mineral obtained experimentally and establishes a correlation between these characteristic parameters. The breakage parameter obtained from the different ...
