摘要

本研究的主要目的是研究固体浓度对细分散石灰浆剪切应力和粘度的影响，这些细分散石灰浆是从选定的石灰加工厂的流动装置中收集的。本文分析的浆料粒径为46μm，固体密度为1140 ~ 1330 kg/m3，固体体积浓度为10.12% ~ 23.70%。结果表明，当固体体积比达到18.28%时，剪切应力随固体体积比的增加而适度增大。当固相浓度大于18.28%(体积比)时，剪切应力呈指数增长。确定剪切应力呈指数增长的边界浓度是确定细分散石灰浆输运参数的基本准则。分析的预期结果应推荐用于输送质量浓度高出数倍的浆料，从而减少水量，同时提高所应用溶液的经济效益。

Influence of Solids Concentration on Solid-Liquid Transportation in a Lime Production Plant

The main objective of the research is examining the influence of solids concentration on the shear stress and viscosity in fine-dispersive lime slurry collected from a flow installation existing in a selected processing plant producing lime. The analysis presented in the paper deals with slurry of average-size particles the diameter of which equals to 46μm, solid density ranges from 1140 kg/m3to 1330 kg/m3and solids concentration by volume from 10.12% to 23.70%. It has been shown that for solids concentration up to 18.28% by volume, the shear stress increases moderately with increasing concentration. If solids concentration is higher than 18.28% by volume, the shear stress increases exponentially. The determination of the boundary concentration above which the increase in shear stress is exponential is a fundamental guideline in determining the transport parameters of fine-dispersive lime slurry. The expected results of the analysis should be recommended for the transport of slurry with several times higher mass concentration and thus reducing the amount of water while increasing the economic profitability of the applied solution.

期刊介绍： WSEAS Transactions on Applied and Theoretical Mechanics publishes original research papers relating to computational and experimental mechanics. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with fluid-structure interaction, impact and multibody dynamics, nonlinear dynamics, structural dynamics and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
