Abstract
A particle size distribution analysis sample dilution apparatus in which a sample consisting of a batch of a slurry of particles is deposited on an inclined plate of a progressive sample delivery system from which a continuous supply of water progressively washes off the sample and dilutes it. The initially diluted sample is further diluted with water continuously supplied in a funnel from which the further diluted sample passes under gravity along a conduit to a particle size distribution analyzer through which the diluted sample flows continuously. The conduit may include a mixing chamber to which water is continuously supplied to further dilute the sample prior to analysis.
