Spiral Launder Systems
into the launders. One launder set per row of spirals is required. 2. Non Engaged Launders: This is where the launders are mounted below the spiral frame, thus hoses are used between the product box and the launders. This allows for more centrally located launder arrangement and both rows of spirals can use the same launder(s).

Computations of Curved Free Surface Water Flow on Spiral Concentrators
Spiral concentrators, consisting of an open trough that twists vertically downward about a central axis, are used to separate radially a thin-film slurry of mineral and waste material on the basis of particle density and size. This paper reports the detailed steady and uniform flow results of a computational fluid dynamics model for the water ...

KREBS® Coal Spirals for fine coal cleaning
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.
