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.
Claims15
A method of incorporating a mineral based particulate into a Portland cement manufacturing process having a burning step, the method comprising:
- agglomerating the mineral based particulate and an agglomerating material to produce an additive;
- and
- introducing the additive into the Portland cement manufacturing process before the burning step.
A system for incorporating a mineral based particulate into Portland cement comprising:
- an agglomerating material that agglomerates the mineral based particulate to form an additive;
- and
- a heat source that burns the additive to form a cement clinker comprised at least in part of minerals from the mineral based particulate.
