Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The cement manufacturing process requires high energy for grinding cement clinker due to its extreme hardness, and existing grinding aids may have limitations in reducing energy consumption and improving cement quality.
Innovation Solution
Incorporating desugared molasses as a cement additive after pyroprocessing, which can act as a grinding aid and performance enhancer by reducing energy requirements during grinding and improving cement reactivity, while being less costly and potentially reducing negative effects of conventional additives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional grinding aids (glycols, alkanolamines, amine acetates, aromatic acetates) are used to reduce grinding energy, then grinding energy consumption is reduced, but cost increases and potential negative effects on cement quality may occur
Solution Approach 1:
The patent uses desugared molasses, a low-cost byproduct of sugar refining, as a grinding aid alternative to expensive conventional additives like glycols and aromatic acetates. This economical substitute maintains grinding effectiveness while reducing cost and potential quality issues associated with conventional chemicals.
Solution Approach 2:
The patent converts desugared molasses, which could be considered a waste product or have limited use, into a functional grinding aid. By removing sugar from molasses and utilizing the remaining components, the invention transforms a potentially harmful or underutilized byproduct into a beneficial additive that reduces grinding energy and cost.
2Use of energy by moving object
If desugared molasses is used as a grinding aid, then grinding energy consumption is reduced and cost is lowered, but the additive must undergo specific processing to remove sugar
Solution Approach 1:
The patent applies preliminary processing to remove sugar from molasses before utilizing it as a grinding aid. This pre-treatment step, while adding processing complexity, is necessary to achieve the desired functional properties and prevent negative effects from residual sugar content.
3Ease of operation
If conventional grinding aids are used to improve powder flow and prevent caking, then handling properties are improved, but manufacturing cost increases
Solution Approach 1:
The patent replaces expensive conventional grinding aids with desugared molasses, a low-cost alternative that provides similar functionality for improving powder flow and preventing caking during storage and handling, thereby reducing manufacturing costs while maintaining operational effectiveness.
