Spiral separator is one of the equipment is used in mineral processing plants. This equipment commonly are used for separation of minerals (coal, iron, chromite, gold, zircon, etc.). Spiral separator performance (yield and product ash content) in addition to factors such as percent solids and flow rate of the feed, largely depends on how the materials exit from the spiral.

A study of coal washing spiral operation and performance is under way at the JKMRC. The program has two components—a pilot plant study, and sampling programs conducted in operating washeries. The objective is to use the pilot plant data to develop a fundamental understanding of the spiral separation process, and to formulate a model of spiral performance which can be subsequently validated

the spiral in washing high ash coal for power plant and blast-furnace applications. The generic geometry of spiral concentrators consists of an open trough that spirals vertically downwards in helix configuration about a central axis. Employed in the fine coal, a slurry mix of fine particles is fed to the top of the spiral and, as it gravitates downwards, particles are segregated radially

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. Optimum spiral feed size is -1 mm to 0.15 mm (14 M x 100 M).
