Additive mixing and delivery system for rotary mixers

Abstract

An additive mixing and delivery system for a rotary mixer is provided. The additive mixing and delivery system includes an onboard slurry tank, an additive pump, a water pump, a spray unit, and a rotor. The onboard slurry tank receives additive and water. The onboard slurry tank mixes the additive with water to form a slurry. The additive pump delivers the additive to the onboard slurry tank. The water pump delivers the water to the onboard slurry tank. The spray unit delivers the slurry from the onboard slurry tank to a work surface. The rotor includes a number of cutting tools to disintegrate the work surface to form a disintegrated work surface. Further, the slurry is mixed with the disintegrated work surface to form an additive laden work surface.

What is claimed is: 
     
         1 . An additive mixing and delivery system for a rotary mixer, the rotary mixer adapted to convert a work surface to an additive laden work surface, the system comprising:
 an onboard slurry tank including an additive inlet to receive an additive and a water inlet to receive water, the onboard slurry tank configured to mix the additive with water to form a slurry;   an additive pump for delivering the additive to the onboard slurry tank;   a water pump for delivering the water to the onboard slurry tank;   a spray unit connected to the onboard slurry tank and configured to deliver the slurry from the onboard slurry tank to the work surface; and   a rotor configured to disintegrate the work surface to form a disintegrated work surface and further mix the slurry with the disintegrated work surface to form the additive laden work surface.
