Abstract

POSTUPAK ZA REGENERACIONU OBRADU STAROG PESKA ZA LIVENJE UGLAVNOM VEZANOG GLINOM, pronalazak se odnosi na postupak za regeneracionu obradu starog peska za livenje uglavnom vezanog glinom, tako što se zrnca peska podvrgavaju naizmenično ubrzanom i usporenom kretanju, dejstvu udara i smicanja, pa se oslobadjaju ljuske koja sadrži vezivne supstance i aditive, tako da se sadržaj vode u starom pesku pre regeneracione obrade svodi na vrednost od najviše jedan maseni procenat vode.The invention relates to a process for the regenerative treatment of old sand for casting mainly bound with clay, so that the sand grains are subjected to alternately accelerated and decelerated motion, which is affected by impact and impact. contains binders and additives, so that the water content in the old sand before regeneration is reduced to a value of not more than one mass percent of water.
