Abstract

The paper presents the grounds for selecting the right types of apparatus for the classification of powderlike berthinate. The results of berthinate classification using both the zigzag-shaped apparatus and the Hukki classifier are summarised. A comparative evaluation of berthinate separation according to Gaudin's index of selectivity and Barsky's coefficient of efficiency is given. The paper contains a description of the results from a comparison of the adsorption capacity of the berthinate classes obtained and the possibility of utilising the classifiers for the separation of different peat products. The work was concluded by obtaining new data on the classification of powderlike products with small (0.2 mm) boundary particles. When investigating the problem for an industrial application, the results obtained can be recommended when working out the technical functions of pilot-plant equipment for peat berthinate classification or a pilot installation for the separation of some other peat products.
