SWECO Unit Doubles Sulphonate Salt Capacity in 24-Hour Operation for Chemical Firm Round-the-clock operation of an 18" diameter SWECO Vibrating Screen Separator has helped double capac ity for Essential Chemicals Company of Fredonia, Wis. This company is one of the nation's large manu facturers of alkyl aryl sulphonate (sodium salt). The company uses this sulphonate salt for its own deter gents and also supplies other manufacturers.
Dust-free operation of this SWECO Separator was a major factor in its selection by Essential Chemicals for use in screening sodium base.

Essential's specifications require a sodium base of uni form particle size, which provides control of product density. Ease of changing screen cloths on the SWECO unit permits rapid selection and installation of desired screen cloth opening. This* enables the company to obtain densities specified by customers. The SWECO Separator requires no attention during operation. Its compactness and dust-free design were major factors in its selection by the chemical firm.
