ABSTRACT

The article presents results of using vibratory jaw crusher for feed preparing for the granulation process. The main aim of the study was to determine the possibility of preparing the limestone feed for non-pressurized granulation process by means of very fine crushing in the laboratory vibratory jaw crusher KW 40/1 with kinematic actuation of jaws. The crusher is characterized by high average degree of fragmentation (30-50). The study was conducted in two stages. The first stage included experiments with vibratory crushing process and the second stage covered examination of non pressurized granulation process. To determine the effect of particle size of crushed limestone on the granulation process it was decided to conduct a study on granulation with two variants of the feed with different particle size distribution. Feed produced for granulation process contained grain class 0-200 microns in the range of 48.4% to 73.0%. This means that vibratory jaw crushers, which have lower energy consumption than any known mill, can be used for production of granulated mineral fertilizers.
