CRUSHERS AND BREAKERS FOR THE PREPARATION OF AGGREGATES: (1) CRUSHING AND GRINDING PROCESSES IN CRUSHERS AND BREAKERS - EXPERIMENTAL METHOD OF STUDYING CRUSHERS AND BREAKERS AND LAWS GOVERNING CRUSHING AND GRINDING PROCESSES

CONCASSEURS ET BROYEURS POUR LA PREPARATION DES GRANULATS : 1) LES PROCESSUS DE FRAGMENTATION MIS EN OEUVRE DANS LES CONCASSEURS ET LES BROYEURS - METHODE EXPERIMENTALE D'ETUDE DES CONCASSEURS ET BROYEURS ET LOIS REGISSANT LES PROCESSUS DE FRAGMENTATION

IN PART 1 THE AUTHOR DESCRIBES CRUSHERS AND BREAKERS AND THEIR CRUSHING AND GRINDING PROCESSES. DETAILS ARE GIVEN OF SIX EXPERIMENTS ILLUSTRATING THE VARIOUS BEHAVIOURS OF BRITTLE MATERIALS: (1) TENSILE FAILURE OF CYLINDRICAL SAMPLES; (2) SAWING FAILURE OF CYLINDRICAL SAMPLES; (3) COMPRESSIVE FAILURE FOLLOWING THE OPPOSITE GENERATORS OF A CYLINDRICAL SAMPLE; (4) COMPRESSIVE FAILURE BETWEEN TWO PLANE SIDES OF A CYLINDER; (5) FAILURE OF A PSEUDO-SPHERE DUE TO UNIAXIAL COMPRESSION AND SIMULTANEOUS PRESSURE OF A FLUID ACTING IN ALL DIRECTIONS; (6) FAILURE OF A PIECE OF ANY SHAPE SUBJECTED TO COMPRESSION. FOR EACH EXAMPLE COMMENTS ON THE ENERGY USED ARE MADE. IN PART 2 EMPHASIS IS PLACED ON THE NECESSITY OF DEFINING AN EXPERIMENTAL METHOD OF STUDYING CRUSHERS AND GRINDERS USING CONCRETE EXAMPLES AND SPECIAL APPARATUS. AN ATTEMPT IS MADE TO STUDY THE LAWS LINKING ENERGY TO CHANGES IN THE NATURE OF MATERIALS.
