ABSTRACT:
Portable metering and mixing apparatus includes a trailer having a hopper thereon divided into two compartments, one compartment for aggregate and another compartment for cementitious material. An auger receives aggregate from one compartment and feeds aggregate into a mixing compartment where cementitious material is added, and the resulting mixture is then delivered as required. Metering elements meter the aggregate and the cementitious material as desired, and the metered aggregate and cementitious material are mixed in a mixing chamber. A metering sleeve over the auger insures that only the metered amount of aggregate is conveyed by the auger to the mixing chamber. A second embodiment utilizes only a single hopper which contains premixed aggregate and cementitious material, and the premix is fed to the auger through a metering sleeve. Water is added to the material while in the auger and prior to the mixing chamber. Heat may be used to heat or warm both the water used for mixing and the material to be mixed. The trailer may also be leveled or lifted, as desired.
