Abstract

The traditional model of closed circuit ball mill systems has been used for several decades, however, if the classifier of the closed circuit ball mill system performs the duties of both pre-classification and check-classification, the characterization error of the traditional model is large. To address this problem, a new model is proposed by modifying the traditional one. The results show that the new model characterizes the relative capacity of the ball mill more accurately, with a concentration of data at 65 % (classification efficiency) compared to the concentration of data at 50 % in the traditional model. The circulating load calculated by the new model is 360.81 %, and the corresponding slurry level in the ball mill is about 50 %, which is more consistent with the actual level. The new model has a higher accuracy than the traditional model in characterizing the production status of the grinding system, which is of some significance for industrial production.

闭路球磨机系统分级性能预测新模型

传统的闭路球磨机系统模型已经使用了几十年，但是，如果闭路球磨机系统的分类器同时承担预分类和检查分类的职责，传统模型的表征误差较大。为了解决这一问题，本文在传统模型的基础上提出了一种新的模型。结果表明，新模型能更准确地表征球磨机的相对容量，与传统模型的数据集中度为50%相比，该模型的数据集中度为65%（分类效率）。新模型计算出的循环负荷为360.81%，相应的球磨机内料浆水平为50%左右，与实际水平较为吻合。与传统模型相比，该模型在表征磨削系统生产状态方面具有更高的精度，对工业生产具有一定意义。

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.
