- The results of investigations of the influence of operation parameters of the prototype vibratory REGMAS reclaimer on matrix grains refinement (destruction) are presented in the paper. Fresh quartz sand ‘Szczakowa’ –1K 0.40/0.32/0.20, J88, >1400oC, WK= 1.20 was subjected to the treatment. Examinations were performed in three stages differing in the frequency of electrovibrators operations (which was: 40 Hz, 50 Hz and 60 Hz). For each frequency two settings of the exciting force of the rotodynamic drives were applied. They were equal 42% and 75% of the maximal exciting force. The sand batch placed in the bottom part of the REGMAS reclaimer was, in individual stages, subjected to elementary operations of grinding, rubbing and crushing. The destruction ratio was determined by means of the classic sieve analysis and grain size analysis performed in the Analysette 22NanoTec apparatus.
