摘要: A method and apparatus for mixing concrete in a delivery truck is provided which can yield mix with an approximate required slump. This achieved by monitoring the torque loading on hydraulic drive rotates barrel noting anticipated minimum which, turn, approximates to slump value. Liquid component added until this noted. CPU (17) used process information derived from pressure sensor (15) connected motor rotate barrel. volume/mass input (21) be meaning amount of particulate ingredients, water volume (25) measure liquid mix. When known maximum computer operate prevent further being added, unless it purposely overridden. The print docket via printer all specified data measured parameters, also transfer main at depot, so as record delivered account processing.
