COHESIVE PROPERTIES OF MODEL POWDERED FORMULAS FOR CHILDREN

In the reported study, analyses were carried out to determine the effect of agglomeration and raw material composition on cohesive properties of model powdered formulas for children. Measurements were carried out in a uniaxial shearing test according to a measuring procedure following Jenike’s theory, at four levels of consolidating stress in the range of 4.6÷17.2 kPa. The examined powdered children formula were determined for the following parameters of plastic flow: cohesion, internal friction angle, resistance to uniaxial compression, maximum consolidating stress and flow index. Characteristics of flowability properties of the examined model powdered formula for children demonstrated various cohesive properties of those materials. The flow function described the model formula powders as poorly cohesive and soft flowing whereas agglomerates produced on their basis as cohesive powders, sparingly flowing.
