2 2 Vacuum belt filters type CHF from ThyssenKrupp Fördertechnik: because sophisticated technology tips the balance Worldwide, ThyssenKrupp Fördertechnik are one of the leading manufacturers of machinery and plants for the mineral processing industry. On the basis of the experience of decades, we are doing research and development work, the result of which became an integral part within mineral processing. All over the world, customers are profiting from our innovative power. Whether standard or special designs ThyssenKrupp Fördertechnik always offer a complete problem solution which is frequently optimised in co-operation with the user. Reliable, safe, economic, innovative ThyssenKrupp Fördertechnik. 1 1 Vacuum belt filters type CHF for solid-liquid separation of slurries in the chemical, food and environmental industry

3 Design, fields of application and characteristic features of vacuum belt filters type CHF 3 Vacuum belt filters type CHF make ThyssenKrupp are belt filters that are operated in fully continuous mode. Contrary to rubber belt filters, the filter cloth of vacuum belt filters type CHF is supported by a reciprocating vacuum tray. Due to the comparatively low weight of the vacuum tray and the absence of tension force required for tensioning the rubber belt, the CHF filter comes up with smaller dimensions and less weight, though the filter surface equals. In addition, the required drive power is considerably lower. Due to their compact and modular design low-maintenance CHF filters are most reliable. Adaptability to varying process requirements ensures an economic operation, whatever the application. Due to the modular design the filter surface of CHF filters can easily be extended or reduced, whenever the process changes. In case of the standard design all parts in direct contact with the product are made out of stainless steel resp. plastics. Fields of application Chemical industry Pharmaceutical industry Food industry Mineral and mining industry Environmental industry Paint and pigment industry Characteristics The fully continuous mode of operation and the consistent supply of slurry and washing liquid ensure a uniform filter cake formation and optimum washing results. The horizontal filtration is supportive of the filtration process due to natural sedimentation. Partitions inside the vacuum tray enable the exact separation of the mother and wash filtrates. Due to the gentle handling during feeding, filtration and washing the mechanical properties of the product are virtually not changed. 2 Vacuum belt filter type CHF in the food industry 2

4 4 ThyssenKrupp vacuum belt filters type CHF: Optimal for wash filtration and dewatering in many industrial sectors The slurry is continuously fed to the horizontal belt filter. Filtration takes place on an endless filter cloth which is supported by a trough-shaped, movable vacuum tray mounted on roller bearings. By vacuum frictional connection the vacuum tray is synchronously moved with the filter cloth during filtration. A frequency-controlled drive allows the filter cycle to be perfectly adapted to the process requirements. When reaching the defined end position, the vacuum tray is atmospherically ventilated and returned to its initial position by means of a pneumatic cylinder. The filtration cycle starts anew. 3 grid filter cake air and filtrate filter cloth vacuum tray 3 Sectional view of vacuum tray 4 Pre-assembled vacuum belt filter type CHF for waste incineration 5 Cloth roller 6 Wash feeder 7 Filtrate manifold 8 Electro pneumatic control box

If no process data is available, filtration tests necessary for designing the filter may be carried out either in the laboratories of ThyssenKrupp Fördertechnik or in the laboratories of the customer. Besides exposed filters, filters with exhaust ventilation, enclosed fume-tight filters or housed filters are available for toxic and hot slurries or if smell nuisance shall be eliminated. Vacuum belt filters from ThyssenKrupp Fördertechnik do also meet the high standards of the food industry. 9 To substantiate to laboratory test result, a leasing pilot filter plant with complete vacuum station is available for field tests.

The widely varying demands on mechanical solid-liquid separation necessitate that each and every filter plant is tailored to the on-site conditions.

7 Research, development and services 7 Research and development are rating highly for ThyssenKrupp Fördertechnik. A committed staff, experience and the ability to also tread new paths as well as innovative power, flexibility and know-how are the basis for a successful partnership with our customers. Our experience and our knowhow are the results of the permanent critical comparison of the design and dimensioning criteria with the results from practical operation. The starting point are analyses and examinations, of which the results are the basis for working out suitable concepts. To that end, methods and processes are adopted which guarantee the best possible solution for the respective task. The values ascertained by calculation are then practically checked using a newly developed control and diagnosis system allowing verification of the most important operating parameters. Our services comprise project studies, damage analyses, planning and execution of conversions for modernising machines and plants and for increasing their capacities as well as an after-sales service worldwide and other services rendered for machines and plants of other manufacturers. The maintenance and repair service of ThyssenKrupp Fördertechnik offers local expert consultation. Repairs are performed by highly qualified assembly staff using high-quality tested spare parts. Increase the productivity of your machines and plants. Contact ThyssenKrupp Fördertechnik worldwide.
