Hydrocyclones are important and economically viable systems for the wet-mechanical separation, classifying and sorting processes of ores and minerals. AKA-VORTEX are applied across the industry in various areas:
- Classification
- Sorting
- Desliming
- Solids recovery
Principle of Operation
The hydrocyclone is in principle a slender full-jacket centrifuge. In contrast to rotating centrifuges, the body of the hydrocyclone remains at rest, while the flow is set into rotation through the tangential inlet under pump pressure. The rotational flow in the hydrocyclone consists of a downward-directed primary vortex and an upward-directed inner secondary vortex, whereby in both cases centrifugal forces lead to the separation of the suspension
Design Features and Client Benefits
- Optimum separation characteristic at varying operating conditions
- Modular system through the use of simple connectors and adaptors (feed part, overflow and underflow nozzle)
- Easy adaption to changing operation parameters
- Fast and trouble-free changing of wear parts
- Low weight of single parts
- Different materials for optimum life time: polyurethane, oxide- or SiC-ceramic, NiHard, titanium, steels
- Can be lined with high wear-resistant, chemical- and corrosion-resistant materials
CONICAL
The CONICAL hydrocyclone is the historical and mainstream version of the AKA-VORTEX series. Used in almost all industrial applications they are available from 20 mm up to 500 mm in full PU.
FLAT-bottom
In comparison to the CONICAL version, the FLAT-bottom design hydrocyclone allows to reach coarser cut sizes. FLAT-bottom types have experienced growing popularity over time.
TWIN
The TWIN type is a version equipped with a proprietary designed feed part, allowing the feeding of two hydrocyclones. It minimizes the investment costs of a hydrocyclone cluster as a result of:
- Reduction in the number of valves
- Optimizing of quantity of steelwork
- Overall footprint reduction
Carbon Steel with Polyurethane Liner
Available in diameters 400, 500 and 660 mm, these hydrocyclones are characterized by high flow rates and can be used for heavy-duty applications, amongst others in the closed grinding circuit applications.Available in CONICAL and FLAT-bottom versions, the apparatus is maintenance-friendly, and the possibility of adapting the polyurethane hardness to the mineral being processed, results in optimum lifetime
