Get PriceMultotec has designed and optimised both single SX4 and double SX7 and MX7 coal spiral concentrators that are supplied with steel rubber-lined or PVCpolyurethane pipe launder systems. The spiral models each have different combinations and have been developed to suit the coal quality. New research and development has shown that our compact, modular designs have added flexibility when
Get PriceSep 01, 2012 In order to efficiently clean fine coals, enhanced gravity separators, such as Knelson concentrator, have been developed. Although the Knelson concentrator has not been applied yet in industrial scale for fine coal cleaning, different investigations have been conducted in recent years. In this study, an oxidized coal with high sulphur was subjected to cleaning process by Knelson concentrator
Get PriceMultotec-designed spiral concentrators are used across the world in coal, gold, iron ore, mineral sands, platinum and chrome processing plants and other minerals.. As a turnkey supplier of gravity concentration equipment across the world, Multotec can deliver end-to-end spiral solutions, from process audits and test work, to complete spiral concentration plants optimised for your process.
Get PriceThe Falcon concentrator is an enhanced-gravity separator used for the concentration of fine and ultra-fine minerals. This study was conducted to evaluate the effects of different process variables on the performance of the Falcon SB-40 concentrator for beneficiation of tailings to recover ultra-fine coal.
Get PriceMar 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.
Get PriceSpiral concentrators are normally used in banks of multiple spirals. Typical capacities for spirals run from 1-3 tons per hour of feed for minerals and 3-5 tons per hour for coal. Typical construction of a spiral concentrator is fiberglass and urethane to reduce wear from abrasion.
