Espirales Spirals Tumphrey Concentrator

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

15.5.3 Spiral Concentrator The spiral concentrator first appeared as a production unit in 1943 in the form of the Humphrey Spiral, for the separation of chrome-bearing sands in Oregon. By the 1950’s, spirals were the standard primary wet gravity separation unit in the Australian mineral sands industry

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

The spiral concentrator is one of the most effective, low-cost devices for the gravity beneficiation of ores. Manufactured from lightweight, corrosion and abrasion resistant materials, spirals require a minimum of maintenance and upkeep. Spiral concentrators offer a relatively simple unit operation that translates to low capital and operating cost
