Description
Summary:The mixing process in a horizontal batch mixer with a twin spiral rotor has been investigated. A mixture of crushed wheat and sodium chloride was mixed in a model mixer. The concentration of sodium chloride in mixture samples was checked as a function of the mixing time and sampling place for various degrees of mixer filling. The sample composition was determined by conductometric determination of sodium chloride in water extracts of the sample. From the values obtained, the mixing degree was calculated as defined by the variation coefficient along the whole mixer, as a function of the mixing time. In analysing the data and empirical correlation between the concentration of component under study and the place and time of mixing, C/ C̄ = f( x, t) was obtained and compared with industrial experiments using radionuclides as tracers.
