Abstract
An agglomerated particulate lignosulfonate material may be made by introducing or forming lignosulfonate microparticles in a fluidized bed agglomerator, and introducing sufficient heated gas and lignosulfonate liquid in the agglomerator to convert the microparticles to lignosulfonate granules of enlarged size. The granules may have an average size of at least 0.1 mm, and may be used to make a dry-blended cement additive or oil well cement that may be dustless, easily poured and stored, and rapidly dissolved in water.
