bétonnière à cuve tournante

OBS: bétonnière à tambour basculant. L'axe de la cuve tournante est incliné. (...) On laisse tourner la cuve (...) et pour vider on la fait basculer.

CONT: In conventional rotating-drum mixers this variation [of as much as 20 % in the proportion of coarse aggregate] is due ... to the lack of interchange of materials from one end of the drum to the other.
