Global leaders in the design and manufacture of spiral concentrators. From mineral sands to environmental recycling, SWMS defines the standard in metallurgical efficiency.
South West Metallurgical Services (SWMS) supplies gravity-based separation equipment and process consultancy to a diverse international market. We are recognized globally as a leading designer of spiral concentrators.
Manufactured using latest reverse lamination technology. GRP construction with polyurethane wear surfaces.
Designed for pulp streams with heavy mineral content up to 50%. Ideal for rougher, scavenger, and retreat duties.
For medium-heavy mineral content (15-80%). Features finger cutters on the helix to divert separated heavy minerals.
Optimised for low ash coal product at high organic efficiency. Rejecting high ash refuse streams.
Polyurethane lined GRP. Utilises a primary feed well with an adjustable annular discharge to control flow.
From lab size samples to fully scaleable spiral performance evaluation.

The LM spiral is primarily designed to treat pulp streams with a heavy mineral content in the range up to 50% by weight. It comprises a backfed feed box, single section of helix and a product boot.
The spiral helix is constructed from GRP with a polyurethane wear surface. The latest reverse lamination technology is used in the manufacturing process. Each LM5 spiral trough has 5 turns beginning at the feed box and ending at the product box.
A heavy duty cast polyurethane feed box is fitted to the trough by means of a bolted flange. The box is back fed with a tangential outlet to ensure maximum use of the spiral separating surface.

The MM series spiral concentrator is primarily designed to treat pulp streams with a medium heavy mineral content in the range 15-80% by weight. It comprises a backfed feed box, single section of helix and a product boot.
A combination of finger cutters on the helix divert separated heavy minerals into an open, inner channel which is part of the trough moulding and terminates in the concentrate area of the product box. Splitters located in the product boot divide the stream into concentrate, middlings and tailings.
The MM spiral requires little attention during operation and is frequently used to further upgrade concentrates produced on LM series spirals.

The GPX spiral is designed to produce a low ash coal product at high organic efficiency while rejecting a high ash refuse stream. The GPX model is the second generation of the very successful CUGP Series spiral.
Each GPX spiral trough has 3.25 turns beginning at the feed box and ending at the product boot. The spiral helix is constructed from GRP with a polyurethane wear surface.
The GPX design has been optimised for better refuse removal and higher capacity.
Raw coal slurry, water-only rejects, flotation tailings, reprocessing existing lagoons, pyritic sulphur removal, sand delignification, soil cleaning.
A spiral module is supplied with the appropriate top or bottom fed static feed distributor to enable each spiral start to be fed evenly. The distributor is constructed from polyurethane lined GRP and utilises a primary feed well with an adjustable annular discharge to control the volumetric flow to the main tank.
The feed is allowed to drain from the feed well to the main tank of the distributor where a head builds up over the outlets. Each outlet is vented to atmosphere to null any siphon effects.
The discharge from the outlets is controlled by venturi type orifice liners which enables fine-tuning of the feed distribution system.
