More than 50 years of experience tradition and know-how Besides technical competence in the successful planning, conception and implementation of projects in the wet-mechanical processing of mineral raw materials and ores, AKW Apparate + Verfahren GmbH has expertise in the treatment of chemical and corrosive media for the chemical, pharmaceutical and food industries.

4 HYDROCYCLONES AKA-VORTEX FOR SOLID-LIQUID-SEPARATION PROCESSES Hydrocyclones AKA VORTEX and annular distributors AKA SPIDER at a high level of development for the processing of minerals, ores, chemical intermediates, alumina and mineral raw materials, as well as by-products. Areas of Application general and across various industries Areas of Application for chemical, pharmaceutical and food industries Sorting Desliming Closed circuit grinding Solids recovery Classification Separation of solids from products and suspensions Classification of solids from corrosive media (e.g. hydrochloric acid) Separation of solids before feed to centrifuges Separation of impurities in low amounts FEED Principle of operation INSIDE VERTEBRAL Discharge of light fraction (Overflow) OUTSIDE VERTEBRAL Discharge of heavy fraction (Underflow) Centrifugal forces are the effective principles of the separation processes in the hydrocyclones. The suspended particles are thrown radially to the outside. Because of the magnified field of force, high settling rates, fast separation and high load are obtained. Flow promoting designs ensure high accuracy of separation.

5 HYDROCYCLONES AKA-VORTEX FOR SOLID-LIQUID-SEPARATION PROCESSES Design features and advantages Materials Optimum separation characteristic at varying operation parameters Long life time of hydrocyclones and distributors due to appropriate material Simple in operation Modular system Easy adaption to changed operation parameters Homogeneous and equal pressure distribution of the suspension on every hydrocyclone in operation FDA approval available > food proof Produced of customized and highly wear-resistant polyurethane, oxide or SiC ceramics, NiHard, titanium Coating with high wear-resistant, chemical and corrosion-resistant materials (rubber, PU ceramic) as an option for all surfaces that come in touch with the suspension Sizes 10 mm to 1,200 mm Types of AKA-VORTEX Hydrocyclone conical Batch working hydrocyclone High-pressure hydrocyclone Hydrocyclone with gritbox Annular distributor AKA-SPIDER Hydrocyclone 660 with changeable PU liner CBC hydrocyclone

6 CLARIFIER-THICKENER AKA-SET FOR WASTE WATER TREATMENT Thickener AKA-SET is a special equipment for thickening, desliming and waste water treatment. Typical application for AKA-SET is processing of minerals, ores, chemical intermediates, alumina and mineral raw materials as well as by-products. Areas of Application General across various industries and for chemical, pharmaceutical and food industries Separation of water Reduction of sludge volume Treatment of process water Thickening of suspensions Principle of operation The flow routing of the flocculated feed slurry in the filtering zone in counter-current to the sedimenting particles causes the formation of macro flocs. These flocs are sedimented at a higher speed than the micro flocs of conventional thickeners. This results in a higher loading rate per unit settling area and smaller thickener diameters, compared to the traditional static thickeners. > High loading rate per unit settling area A sufficiently dimensioned compression zone with a multi-arm raking mechanism ensures a high degree of thickening. The raking bars ensure an extremely good subsequent dewatering in the thickening zone. > High and uniform sludge concentration The clarified liquid and filtering zone which is monitored by instrumentation and control engineering devices ensures high clarification efficiency and a good clarified flow quality. > High clarified flow quality Optional: Skimmer system

7 CLARIFIER-THICKENER AKA-SET FOR WASTE WATER TREATMENT Outlet Instrumentation and control equipment Clarified fluid zone Suspension inlet Filtering zone Compression zone Design features and advantages Materials High loading rate per unit settling area Huge throughput Space-saving design Constantly high sludge concentration Fully automatic operation Good utilization of the flocculants Flexible adaption to varying operating conditions Low operating costs Minimum maintenance requirements Produced of customized and corrosionresistant materials (steel, stainless steel) Coating with chemical and corrosionresistant materials as an option (rubber, PU ceramic) Size 2.8 m to 18.0 m
