Title
(EN) A BLOCK-MAKING MACHINE
(FR) MACHINE A BLOCS
Abstract
(EN)
A block-making machine (1) which is distinguished by notably economical operation, both in terms of energy consumption and in terms of the duration of the production cycle of artificial concrete blocks (C), and at the same time maintains a high level of quality of the blocks (C) produced, comprises a vibrator plate (18) and at least one vibration generator (21) connected to the vibrator plate (18) and having a rotating eccentric element (37) which comprises a first mass (39) rotating on an axis (A), a second mass rotating on the axis (A), and means (47, 52, 57) for varying the relative angular positions of the first and second masses (39, 42).
(FR)
Cette machine (1) à blocs se distingue notamment par un fonctionnement économique, à la fois en terme de consommation d'énergie et en terme de durée du cycle de production de blocs (C) de béton au basalte, tout en maintenant un niveau élevé de qualité des blocs (C) produits, et elle comprend une plaque oscillante (18) ainsi qu'au moins un générateur (21) d'oscillations relié à cette plaque (18) et présentant un élément (37) excentré rotatif, lequel comporte une première masse (39) tournant autour d'un axe (A), une seconde masse tournant autour de l'axe (A), ainsi que des moyens (47, 52, 57) servant à faire varier les positions angulaires relatives des première et seconde masses (39, 42).
