High Performance Attrition Cells A K A - TRIT The attrition process is used for cleaning raw and residual materials contaminated with adsorbed impurities or pollutants. In this process, the individual particles are stirred intensively in high-solid slurry, which causes any adherent pollutants or extremely fine particles to be rubbed off the particle surfaces. The patented high-performance attrition system of AKW Apparate + Verfahren GmbH enables a consistently effective attrition even under fluctuating inlet conditions Principle of operation In a high performance attrition the process conditions...

High Performance Attrition Cells A K A - TRIT Design features and advantages – Tank with vertical agitator and V-belt drive – 2-, 4- or 6-cell construction with chamber volume each cell 0.5 m³; 1.0 m³; 2.0 m³; or 3.0 m³ – Robust, wear-resistant and low-maintenance construction in steel/stainless steel with easily replaceable wear protection (rubber/PU) for tank and agitator – Computer-controlled, defined solids concentration – Connection to existing plant control system is possible – Retrofitting of existing attrition plants for high-performance attrition is possible Applications – Processing...

Hydrocyclones A K A - V ORT E X and Annular Distributors A K A - SPID E R Hydrocyclones are important and economically valuable components for wet-mechanical separation and classifying processes of minerals and mineral raw materials – matured construction, compact design and continuously developed and improved. Annular distributers in fully automatic mode allow a homogeneous and equal pressure distribution on every hydrocyclone in operation. AKA-VORTEX and AKA-SPIDER are applied across the industry in various areas: sorting, desliming, closed circuit grinding, solids recovery, classification....

Hydrocyclones A K A - V ORT E X and Annular Distributors A K A - SPID E R TYPES AND SIZES OF HYDROCYCLONES NominalØ mm – Mineral raw materials and by-products (e.g. foundry sand, slag, Si-SiC-slurry, abrasives) Hydrocyclones are successfully in operation for classification of fine fractions of: – Minerals (e.g. Kaolin, Feldspar, Talcum, Chalk, Quartz, Gypsum, Bentonite, Zircon) – Ores (e.g. Iron ore, Bauxite, Zinc ore, Tin ore, Manganese ore, Chromite ore, Niobium-Tantalite-ore) – Chemical intermediates APPLICATIONS FOR CUT SIZE RANGES d50 FROM 2 μm UP TO 180 μm Types of AKA-VORTEX – Hydrocyclone...

Modularity of the components The modular arrangement on the building block principle makes the series AKA-VORTEX flexible and adaptable to different operating conditions. Due to the possibility to combine different components of the AKA-VORTEX in different versions, several modifications with respective flow rates and results can be created from a series. Example AKA-VORTEX RWH8124: Drawing Capacity / Throughput curves for hydrocyclone 350 Test-Medium: Water Temperature: 20°C Data for Poyurethane 300 Special versions of the AKA VORTEX With our modern equipped laboratory and a close cooperation...

Flat-bottom hydrocyclones AKA-VORTEX CBC Assembly flow, resulting from high centrifugal forces in the upper part and low centrifugal forces in the lower part of the hydrocyclone, transport pressure-compensated particles on the flat ground to the middle and allow the discharge with little risk of blockage. The hydrocyclone is maintenance-friendly equipped with a removable, highly wear-resistant PU liner. For the PU liner different qualities according to the requirements can be selected and allow accordingly applications under a variety of conditions and temperature environments. Hydrocyclone with...
