An operational model for a spiral classifier

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).

Mechanical Centrifugal Air Classifiers

Moisture effects are limited by surface moisture, rather than inherent moisture. Inherent moisture is naturally found inside particles of ores, minerals or stone sand after natural drying occurs in air. Inherent moisture does not hinder an air classifier's ability to remove fine powder or fine dust from coarse particles.
