Mobile asphalt concrete production machine
First Claim
1. A mobile asphalt mixing machine, comprising:
- a mobile frame having a fines storage bin with a discharge aperture into a first bin conveyor, said first bin conveyor leading to an elevator transfer area;
a first aggregate storage bin having a discharge aperture into a second bin conveyor, said second bin conveyor leading to said elevator transfer area;
a second aggregate storage bin having a discharge aperture into a third bin conveyor, said third bin conveyor leading to said elevator transfer area;
an elevator conveyor aligned with said elevator transfer area to lift material from said elevator transfer area to a mixing trough;
wherein said mixing trough has a mixing auger extending longitudinally through said mixing trough, said mixing auger forwarding material deposited by said elevator conveyor through said mixing trough and to a mixing trough exit;
a bitumen nozzle adjacent said mixing trough and aligned therewith to deposit liquid bitumen into said mixing trough;
at least one heating device directing heat into said mixing trough;
wherein said mixing trough has a recycling exhaust fan and is partitioned by a baffle into a first portion and a second portion, said first portion having an air intake of said recycling exhaust fan and said second portion having an air exhaust of said recycling exhaust fan.

Abstract
A mobile asphalt production machine which includes support for different asphalt concrete recipes including a plurality of aggregate storage bins which work on combination with a fines or sands storage bin. The individual bins have separated feeding chutes to the mixing trough. The machinery also includes a removable pan at the elevator transfer station to accommodate changeover from one grade aggregate material to another. Further, a controller is provided which delivers appropriate ingredients while also measuring process parameters to adjust various input requirements. Further, a dust and particulate recapturing system is provided which recycles particulate matter back into the ribbon of mixed material with a binding agent.
