A disperser is a type of mixer used to rapidly break apart lumps of powdery material, uniformly distributing and wetting them in a liquid. It is also used to dissolve soluble solids in liquid. Dispersers are available with single, two speed, and variable speed mixing shafts. Hockmeyer dispersers have been on the market for over 50 years and have a track record of reliability, and durability second to none. All Hockmeyer disperers can be customized to meet the needs of your plant, with hoist mounted, tank mounted, and custom multiple tank position options. Agitators are generally used to blend multiple liquids or to keep solutions homogeneous after dispersion.
