A series of experiments have been carried out in a spiral classifier to study theeffects of design variables(weir height and slope)and operating variables(feed flowrate,pulp density,and size distribution)on the performance of the elassifer.The ana-iysis of the experimental data has led to the development of a mathematical model ofa spiral classifier which consists of four basic equations that express the cut size(cor-rected d_(50)),water split between overflow and sand,reduced-Performance curve and thefinest size fraction appearing in the sand product,in terms of the operating and designvariables.This study shows that a spiral classifier model can be developed based on the co-ncepts of corrected d_(50) and the reduced-performance curve as is done for the hydrocy-clone classifer.The corrected performance curve for the spiral classifier was determinedmost effectively based on the finest fraction in the coarse product.
A series of experiments have been carried out in a spiral classifier to study the effects of design variables (weir height and slope) and operating variables (feed flowrate, pulp density, and size distribution) on the performance of the elassifer. Ana-iysis of the experimental data has led to the development of a mathematical model of a spiral classifier which consists of four basic equations that express the cut size (cor-rected d_ (50)), water split between overflow and sand, reduced-performance curve and thefinest size fraction appearing in the sand product, in terms of the operating and design vessels. This study shows that a spiral classifier model can be developed based on the co-ncepts of corrected d_ (50) and the reduced-performance curve as is done for the hydrocy -clone classifer. The corrected performance curve for the spiral classifier was determined to effectively based on the finest fraction in the coarse product.
