REFLUX™ Classifier

advancements in channel spacing and width, our REFLUX Classifiers are both efficient and compact. Developed with your entire minerals processing plant in mind, the REFLUX Classifier (RCTM) separates small particles based on a difference in density or particle size. The RC combines a conventional fluidised bed separator with a set of parallel

An operational model for a spiral classifier

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).

Grinding & Classification Equipment

JXSC grinding & classification equipment is the key equipment for crushing materials after they are crushed. The ball mill can process various grinding minerals, non-ferrous metal beneficiation, and new building materials. It is often combined with a spiral classifier to form a closed-circuit ring mill, which has higher fine powder and grinding power.

Introduction to Mineral Processing or Beneficiation

Hydrocyclones have become one of the most important and widely used classifiers in the mineral processing industry. They are also used for de-sliming, de-watering, de-gritting and thickening processes. They are most commonly employed in closed circuit within grinding circuits and are used to return coarse material back to the ball or rod mill ...

Spiral classifier or hydrocyclone

Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & Exploration Mineral Processing Handbook called "Mechanical Classifiers". The principal use of mechanical classifiers has been in closed circuit wet grinding; however, this application has been widely displaced over the past few decades by the hydrocyclone.

In most mineral processing circuits comminution is carried out to liberate the valuable minerals prior to subjecting the ore to a recovery process were values are concentrated or extracted (Mainza, Evertsson, Benzer, Tavares, Powell, Rule, Plint, …, 2013). Comminution is an energy intensive process and is usually achieved in stages.
