A combination of sieve and lpsa analysis is recommended to generate an accurate particle size distribution. for samples comprised of coarsegrained particles, sieve analysis is recommended. for samples with very fine particles, lpsa is recommended. the sand log directly measures the sandsized fraction from cuttings and cores.

Load ranging from 200 per cent of new feed to a maximum of 350 per cent. these volumetric loads required a maximum of four cyclones in use with two on standby. operation of the circuit has shown that the recirculating loads are significantly greater than design, at times approaching 500 per cent of new feed requiring up to six cyclones.
Methods of particle size determination. there are a number of methods used to monitor particle size distribution. the most popular of which include sieve analysis, direct imaging and laser diffraction. historically, particle size distributions were calculated based on results from sieve analysis.

The handling of a raw material in a grinding process will be closely linked to the nature of its particles. the choice of an industrial mill depends mainly on three factors that must be taken into account: the nature of the raw material: is it abrasive, oily, hard, brittle, elastic, heatsensitive, hygroscopic the particle size distribution (average size and variance) of the final product.
The main object of the party in visiting this place being the determination of the 49th degree of latitude, mr. colhoun lost no time in taking observations. the first one which he made was near mr. nolen's house, and although not very satisfactory, yet it showed that we were near to the boundary line, as it indicated 48 59' 27 .
