Abstract
A method and an apparatus for dispersing or dissolving a pelletized material in a liquid, in which a pelletized material is placed on a platform in a container having a lower chamber portion, and a stream of liquid is introduced into that lower chamber to produce a vortex of the liquid which washes across the pelletized material, thereby causing it to become dispersed or dissolved into the liquid. In installations where the flow rate of the liquid is below a certain level, a supply of compressed air is injected into the liquid of the lower chamber to prevent mudding of the material.
