An Improved Structure Design of Rolling Drum for the Mixture of Different Sizes of Particles

Article Preview

Abstract:

In many industries, such as chemical industry, food industry and cement industry, rolling drum are widely used for the mixing of solids which in many cases is the mixture of particles of different sizes. The quality of product is directly determined by the mixing uniformity, thus it is desired to guarantee the stability of mixing extent of rolling drum. This paper describes a new structure design for the mixture of different sizes of particles, and an image-analysis-based experimental method to verify the effectiveness of this new structure. Results of the experiment showed that using the new structure would enable a faster mixing rate, and obtaia higher mixing extent relative to the traditional structure.
