Abstract

In the cement grinding process, the operating indicators are interdependent, and the working conditions fluctuate dynamically. Since cement quality and unit electricity consumption cannot be monitored in real time and there is a lack of coordination between the operating indicators, the quality of cement remains unstable, and energy efficiency is compromised. This paper proposes a dynamic multi-objective optimization method based on a transfer learning and evolutionary optimization framework to investigate the dynamic optimization of the cement grinding process in a variable environment. Firstly, the specific surface area (Powder fineness) and unit unit electricity consumption of cement were selected as optimization targets to construct a multi-objective optimization model. Subsequently, a multi-objective optimization algorithm based on knowledge-guided logistic regression is introduced to address the model and optimize performance under dynamic conditions. The algorithm is applied to the cement grinding process, achieving the goal of reducing unit electricity consumption while maintaining the specific surface area.

基于知识引导逻辑回归的水泥粉磨过程动态多目标优化方法

水泥粉磨过程中，运行指标相互依存，工况动态波动。由于水泥质量和单位用电量无法实时监控，运行指标之间缺乏协调，导致水泥质量不稳定，影响能效。本文提出了一种基于迁移学习和进化优化框架的动态多目标优化方法，研究了变环境下水泥粉磨过程的动态优化问题。首先选取水泥的比表面积（粉细度）和单位单位电耗作为优化目标，构建多目标优化模型；随后，引入了一种基于知识引导逻辑回归的多目标优化算法来解决模型问题，并在动态条件下优化性能。将该算法应用于水泥粉磨过程中，达到了在保持比表面积的同时降低单位电耗的目的。

期刊介绍： Powder Technology is an International Journal on the Science and Technology of Wet and Dry Particulate Systems. Powder Technology publishes papers on all aspects of the formation of particles and their characterisation and on the study of systems containing particulate solids. No limitation is imposed on the size of the particles, which may range from nanometre scale, as in pigments or aerosols, to that of mined or quarried materials. The following list of topics is not intended to be comprehensive, but rather to indicate typical subjects which fall within the scope of the journal's interests: Formation and synthesis of particles by precipitation and other methods. Modification of particles by agglomeration, coating, comminution and attrition. Characterisation of the size, shape, surface area, pore structure and strength of particles and agglomerates (including the origins and effects of inter particle forces). Packing, failure, flow and permeability of assemblies of particles. Particle-particle interactions and suspension rheology. Handling and processing operations such as slurry flow, fluidization, pneumatic conveying. Interactions between particles and their environment, including delivery of particulate products to the body. Applications of particle technology in production of pharmaceuticals, chemicals, foods, pigments, structural, and functional materials and in environmental and energy related matters. For materials-oriented contributions we are looking for articles revealing the effect of particle/powder characteristics (size, morphology and composition, in that order) on material performance or functionality and, ideally, comparison to any industrial standard.
