Abstract
A method of rinsing a slurry contained between a pair of converging mesh belts comprising the steps of splitting the slurry into two streams, each stream adjacent one of the converging mesh belts, introducing a stream of rinsing fluid between the two slurry streams, the point of introduction of the rinsing fluid between the two slurry streams is not more than 12 inches before and not more than 72 inches after the slurry streams contact the converging mesh, and creating compressive forces within the pair of mesh belts, which compressive forces continue for a distance of at least 24 inches after introduction of the stream of rinsing fluid.
