Abstract
The present invention provides methods and systems of incorporating a mineral based particulate into Portland cement including agglomerating a particulate material and an agglomerating material to produce an additive, introducing the additive into a raw feed before burning the raw feed. By introducing the additive before burning, minerals are added to cement clinker.
Claims16
A method of incorporating a mineral containing particulate into a Portland cement manufacturing process having a burning step, the method comprising:
- agglomerating the mineral containing particulate and an agglomerating material to produce an additive;
- and
- introducing the additive into the Portland cement manufacturing process before the burning step.
A method of incorporating a mineral containing particulate into a Portland cement manufacturing process having a burning step, the method comprising:
- agglomerating the mineral containing particulate and an agglomerating material to produce an additive, wherein the agglomerating material comprises at least one of a water soluble paint, a water soluble ink, a paint sludge, a paint wash water, and an adhesive;
- and
- introducing the additive into the Portland cement manufacturing process before the burning step.
A method of incorporating a mineral containing particulate into a Portland cement manufacturing process having a burning step, the method comprising:
- agglomerating the mineral containing particulate and an agglomerating material to produce an additive, wherein the mineral containing particulate comprises at least one of lime kiln dust, cement kiln dust, mineral extraction tailings, cracking catalyst fines, iron ore fines, fly ash, baghouse fines, and powder coating dust, and the agglomerating material comprises at least one of a water soluble paint, a water soluble ink, a paint sludge, a paint wash water, and an adhesive;
- and
- introducing the additive into the Portland cement manufacturing process before the burning step.
