An operational model for a spiral classifier
1. 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).The …

What is Spiral Classifier in Mineral Processing?
The spiral classifier can be divided into three types: high dam type, low dam type and submerged type. 1). High Dam Spiral Classifier. The high dam type spiral classifier means that the overflow dam is higher than the spiral axis of the spiral, but lower than the upper edge of the spiral at the overflow end.

An operational model for a spiral classifier
Spiral classifiers. A typical spiral classifier is shown in Fig. 1. The geometry of a spiral is characterized by the length or number of turns, the diameter, the pitch and the shape of the trough (Burt, 1984). The spiral feed is a mixture of water and ground particles that is gravity fed at the top of the spiral.

Spiral Classifier Structure, Working Principle, Feature, …
Spiral classifier uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel. Material is discharged from the upper by spiral, so as to finish the grading work.

Least Squares Support Vector Machine Classifiers
In this letter we discuss a least squares version for support vector machine (SVM) classifiers. Due to equality type constraints in the formulation, the solution follows from solving a set of linear equations, instead of quadratic programming for classical SVM's. The approach is illustrated on a two-spiral benchmark classification problem.
