Our spiral separators are made of high quality polyurethane with fiberglass banking and wearable corundum inner surface.Generally there are 5 turns in one start and four starts in one column. They can be used for mienral particle sized from 0.02 to 0.3 mm, with processing capacity from 2 to 4 t/h per column. 4 or 6 columns can be joined to form ...
Spiral concentrators are gravity-based and used to separate low-density granular and sandy (from 18 mesh to 200 mesh—1 mm to 0.0757 μm) materials from higher-density materials. Spiral concentrators are used in many mineral processing applications. For instance, they're used to process heavy mineral sand deposits, more specifically …
The Knelson Continuous Gravity Concentrator was developed to address specific mineral recovery applications which semi-batch-concentration methods are unable to achieve. It is the only continuous gravity concentrator that utilises fluid-bed technology and avoids non-fluidised flowing film separation which, when used at higher G-forces, …
Test rig A Mineral Deposits Reichert LD4 coal spiral was chosen for the experiments. This spiral has a large diameter and flatter profile with a shallow pitch and six turns. The spiral was run in closed circuit with an automatic sampler to achieve accurate sampling. It was fitted with two splitters.
The present investigation deals with a novel approach to recovering individual critical industrial minerals from a new lean-grade beach sand deposit in Bramhagiri, Odisha, India. This sand deposit contains 3.43% ilmenite, 0.16% rutile, 0.82% garnet, 0.87% zircon, 0.11% sillimanite and 0.01% other heavy minerals. Spiral concentrators …

During the last two years spiral concentrators have become the predominant gravity concentration device in the Mineral Sands industry, replacing cones, pinched sluices and trays. In 1985 and 1986 every new or renovated Mineral Sand concentrator has installed spiral concentrators, in many cases replacing Reichert Cones. This renaissance of
