Abstract
A densification system for shredding and densifying specification raw materials for use as an alternative fuel source. The densified specification raw materials formed by the inventive system are readily transportable to a fuel processing site where they may be used to generate energy.
Claims12
A densification system comprising:
- a plurality of shredders, wherein the shredders shred specification raw materials into a desired size range and density;
- an air shear non-ferrous metal remover for separating out specification raw materials containing non-ferrous metals and for removing the shredded specification raw materials containing non-ferrous metals;
- a ferrous metal remover for separating out specification raw materials containing ferrous metals and for removing the shredded specification raw materials containing ferrous metals;
- and
- a cuber for densifying the shredded specification raw materials into a desired densified form having desired dimensions.
2 more elements
A method for preparing densified specification raw materials by a densification system, the method comprising:
- shredding a first group of specification raw materials having a first range of sizes and densities via a first shredder;
- shredding a second group of specification raw materials having a second range of sizes and densities via a second shredder;
- combining the shredded specification raw materials from the first group and second group of specification raw materials to form a third group of shredded specification raw materials;
- further shredding the third group of shredded specification raw materials to form a fourth group;
- removing those shredded specification raw materials from the fourth group that contains non-ferrous metals;
- removing those shredded specification raw materials from the fourth group that contains ferrous metals;
- and
- densifying the fourth group of shredded specification raw materials by passing the third group of shredded specification raw materials through a cuber, wherein the cuber results in a plurality of densified specification raw material forms.
5 more elements
A method for preparing densified specification raw materials using a densification system the method comprising:
- in-taking a first group of specification raw materials having a first range of densities;
- shredding the first group of specification raw materials to a desired size range to form a first group of shredded specification raw materials;
- in-taking a second group of specification raw materials having a second range of densities;
- shredding the second group of specification raw materials to a desired size range to form a second group of shredded specification raw materials;
- transporting the first and second groups of shredded specification raw materials to a secondary shredder, wherein the first and second groups of shredded specification raw materials are further shredded to form a third group of shredded specification raw materials;
- removing non-ferrous metal-containing shredded specification raw materials from the third group of shredded specification raw materials;
- removing ferrous metal-containing shredded specification raw materials from the third group of shredded specification raw materials;
- treating the third group of shredded specification raw materials with at least one of lime, urea, and vermiculite;
- transporting the third group of shredded specification raw materials to a cuber, wherein the cuber densifies the shredded specification raw materials into a plurality of densified forms;
- recycling any excess specification raw materials that cannot fit into the cuber back through the densification system;
- collecting the plurality of densified forms into at least one of a live load conveyance or a storage conveyance.
