- Mineral Sprial Classifier Anually
A spiral classifier and a hydrocyclone are the two main classification equipment. For decades, the spiral classifier has been widely used in ore dressing plants as first-generation grading equipment. As second-generation grading equipment, hydrocyclones quickly occupy a place in the grading equipment of the concentrator due …

In contrast, dynamic classifiers have a variable speed rotating cage which allows adjustment of the cut size (Altun et al., 2016).Since their introduction in 1885, Altun and Benzer (2014) dynamic centrifugal air classifying equipment has evolved through three generations. In the first generation classifiers, as shown in Fig. 3 b, an integrated …

Introduction. The processing of heavy minerals and coal is often carried out using spiral classifiers. Processing of iron ore to separate coarse iron oxides such as hematite from light gangue mineral, such as quartz, is carried out in circuits with several hundreds of rougher, cleaner and re-cleaner spirals (Bazin et al., 2014).
