spiral circuits in mineral processing

Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

Heavy Mineral Sand an overview ScienceDirect Topics

Spiral circuits have been installed to process the size range that is least effectively treated by these two methods, typically 0.1–2 mm (Honaker et al., 2008). A notable innovation in fine coal processing is the incorporation of multistage separators and circuitry, specifically recycling middling streams ( Luttrell, 2014 ).
