  • Patent number: 4356723
    Abstract: The slump of aggregate within a continuously rotatable container is under constant surveillance by measuring the hydraulic pressure within the transmission connecting the motor and the container. Hydraulic pressure at a calibrated continuous speed of the container is correlated to the slump value of the aggregate regardless of the quantity of aggregate within the container so that the aggregate is accurately and continuously measured from the time it is charged to the mixer to the time of on-site discharge. As previously stated, the aggregate is continuously measured both during the time it is charged and at the time of on-site discharge, i.e., during counterrotation of the container.
