PARTICLE SIZE DETERMINATION BY THE SHARPLES MICROMEROGRAPH

Abstract

The theory and operational technique of the Sharples Micromerograph are described. An investigation was carried out to assess its efficiency as an automated weight sedimentometer for the evaluation of weight/size distribution of particulate materials. Results show that its accuracy is reduced by failure to sediment the whole of the powder under test, this effect being accentuated in the case of most fine powders. The instrument cannot be used satisfactorily for control work unless electrostatic charging of the sedimenting material is eliminated and a modification is suggested.
