Dispersers
A wide range of industrial processes rely on blenders, mixers, and agitators to mix chemicals and materials as a portion of their production process. In most cases, the substances that are being blended or mixed have similar consistencies and are easily combined. When unlike materials with different consistencies, such as powders, granules, and other dry materials, need to be mixed, a greater amount of force is necessary to break down lumps and chunks that the traditional blending process is unable to disintegrate. A disperser is a form of mixing device that uses high speed and concentrated force to dissolve, disintegrate, and dissipate solids that form in liquids and powdered substances during the blending and mixing process. Using disc shaped blades attached to a mixing shaft, the blades of the device rotate at maximum speed to achieve proper flow, consistency, and dispersion.

Applications of Dispersers
Mixing of ingredients is a natural part of food production, which uses mixing equipment that matches the needs of the substances being blended. Dispersers are a necessary part of the process of liquifying solid ingredients and ones that solidify during storage. Specialty foods such as blended cheeses, salad dressings, and spicy foods necessitate dispersion to be properly blended.
Aside from the food industry, other industrial operations use blending and mixing as a part of their processes. In many cases, the substances that are being blended are incompatible and require extra force to break them down for proper mixing and blending. This is especially true in cosmetics, adhesives, coatings, and pharmaceutical production where the proper blending and composition of the materials is necessary for the quality of the final product. The unique array of chemicals and materials that are used to produce high quality and safe commercial goods requires blending processes that can meet the needs of the application.
Factors to Consider When Using Dispersers
Determining the proper amount of dispersion is dependent on the size of the mixing container and materials that are being mixed. The function of a high-speed disperser is to reduce lumps, pieces, solids, and masses to a particulate form necessary for the blending application. Dispersion is accomplished through the use of a counter current process that subjects clumped materials to sufficient force to disintegrate and pulverize them.
As with any form of heavy-duty equipment, dispersing machinery has to be applied to an application properly. In the case of high-speed specially designed equipment (HSDs), there are precisely defined conditions that have to be followed for the equipment to perform properly. The use of an HSD in a mixing tank that is too large or too small will damage it and produce poor quality blending. It is essential that an HSD be operated at its design ratio, which includes a shaft speed of 4800 to 5200 fpm. The purpose and function of a disperser is to break down dry agglomerates in liquid substances and wet-dry particulates to produce a stable particle size.
