Online spiral grade control
spiral concentrator, optimization, online control, grade-recovery tradeoff. Introduction Gravity spiral separators are widely utilized for the physical separation of a number of ore types. In the South African context, gravity spirals are used extensively in the concentration of chromite, coal, and mineral sands.
Simulation of particle-laden flow in a Humphrey spiral concentrator
The curvature of the helix in this case can be controlled by varying the ratio of the semi-major axis to the semi-minor axis, k. A spiral with a smaller curvature can be achieved by increasing k. We varied k from 3/3 to 6/3, and the semi-minor axis correspondingly varied from 0.45 to 0.225 m. For a surface on a given ellipse, the …

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.
Reverse Helix Gold Trommel
Another concentrator device based on the spiral design is the helix gold trommel. A helix is a cylinder lined with spirals along the inside. Helixes are suitable for use as roughers or cleaners, depending on their size. Sizes range from small 1 foot diameter by 5 feet long cleaners to large roughers 8 feet in diameter and 40 feet long (Photo 8).
