Sx4 coal spiral concentrators

Outotec spiral concentrators are used in most applications, particularly for concentrating low-grade ores. Manufactured from lightweight, corrosion and abrasion-resistant materials, our spirals require minimal maintenance and upkeep. Gives you an effective and low-cost solution for gravity separation. Reduces maintenance with a durable design

    Coal/Mica Spiral Spiral Concentrators Larger diameter units than the mineral-spiral series, these spirals are designed to take advantage of the particle shape differences. Take-off splitters at different points down the helix give this spiral a high capacity to remove refuse or siliceous contaminants from the coal or the mica

    Spirals in coal processing are high capacity, lightweight fiberglass construction, use no power, use no reagents and effectively remove pyrites from coal. Most spirals are available in single start, double start or triple start versions, giving two or three times the capacity for the same floor space. Single spiral test stand is also available

    2007; Benasa, 2007, and Mathew et al., 2008), spiral concentrators have the ability to achieve effective separations for particle size fraction of less than 150 m down to 45 m. The objective of this study is to evaluate the effectiveness of in-plant ultrafine spiral concentrators for cleaning ultrafine coal at size interval of -150 m+44 m

    Spiral coal concentrators use the specific gravity of materials with different densities to separate coal, and produce a low-ash coal product at high efficiency. Our high-performance Coal Spirals deliver a feed capacity of 2 STPH to 3 STPH (1.8 mtph to 2.7 mtph) per start, dependent on raw coal quality and refuse amount to be discarded

    Mar 26, 2016 The Humphreys Spiral Concentrator is a simple, efficient gravity concentrator which effects a separation between minerals of the proper size range that have sufficient difference in their specific gravity. This concentrator is a spiral conduit of modified semi-circular cross-section, with outlets for removal of concentrate and middling
