Abstract
A system and method for grit recycling includes a first stage and a second stage. The first stage includes a first apparatus adapted to coarsely separate reusable grit from waste material. The second stage is positioned adjacent the first stage such that the coarsely separated reusable grit from the first outlet of the first stage is automatically input to the second stage. The second stage includes a second apparatus adapted to finely separate the reusable grit from the waste material.

A grit recycling system, comprising:
- a first stage, the first stage including a first apparatus adapted to coarsely separate reusable grit from waste material, the first stage including an inlet, a first outlet for the coarsely separated reusable grit, and a second outlet for the waste material, the first stage including a screened auger including a screen having holes sized to allow the coarsely separated reusable grit to pass through the holes and into the first outlet while the waste material moves laterally toward the second outlet;
- and
- a second stage positioned adjacent the first stage such that the coarsely separated reusable grit from the first outlet of the first stage is automatically input to the second stage, the second stage including a second apparatus adapted to finely separate the reusable grit from the waste material, a third outlet for the finely separated reusable grit, and a fourth outlet for the waste material.
An apparatus for grit recycling, comprising:
- a first housing, including a first inlet, a first outlet, and a second outlet;
- a first filter disposed within the first housing, the first filter comprising a screened auger including a screen having holes sized to allow coarsely separated reusable grit to pass through the holes and into the first outlet and to prevent waste material from passing through the holes;
- a second housing including a second inlet, a third outlet, and a fourth outlet, the second housing positioned below the first housing such that the coarsely separated reusable grit from the first outlet of the first housing is adapted to feed into the second inlet of the second housing;
- a second filter disposed within the second housing;
- and
- at least one power supply electrically coupled to the first filter and the second filter.
