STUDY OF THE PROBLEMS CONNECTED WITH THE PRODUCTION OF AGGREGATES

ETUDE DES PROBLEMES D'ELABORATION DES GRANULATS

THE KNOWLEDGE OF THE PERFORMANCE OF AND POSSIBILITIES OFFERED BY THE EQUIPMENT USED IN THE PRODUCTION OF AGGREGATES AND THE INSTALLATION OF AUTOMATIC DEVICES ARE INDISPENSABLE TO CARRY OUT THE CONTROL OF AGGREGATES IN QUARRIES. IN 1979 IT IS ENVISAGED: - TO HARDEN AND REFINE AGGREGATES BY MEANS OF THE CLASSIFYING CYLINDER; - TO INSTALL A CONTROL DEVICE FOR THE RECOMPOSITION OF AGGREGATES IN THE QUARRY BY MEANS OF THE LAMP 305 DATA ACQUISITION SYSTEM; - TO USE RADIO-ELEMENT EQUIPMENT TO CLASSIFY MATERIALS SENT TO PRODUCTION CHAINS IN QUARRIES; - TO STUDY THE DIFFICULTIES OF OBTAINING 4/60 GRAVEL HAVING A SATISFACTORY BEHAVIOUR UNDER TRAFFIC; - TO STUDY A GYRATORY CRUSHER; - TO STUDY A BAR CRUSHER. THIS RESEARCH PROJECT PARTIALLY SUPERSEDES IRRD RESEARCH PROJECTS NOS 500285 AND 500485.
