Over-pressure and under-pressure filter technologies
All Outotec Larox filter technologies are based either on over-pressure, including automatic vertical pressure filters, horizontal filter presses and polishing filters, or on under-pressure, including horizontal vacuum belt filters, ceramic disc filters and conventional vacuum disc and drum filters.
The Outotec filter product names used to known as Larox, Ceramec, Hoesch, Pannevis, Scanmec and Scheibler. Most of the product names have served the markets for several decades and all of them are supported by Outotec aftermarket services.
Automatic pressure filters
Outotec's M-Series automatic pressure filters run in many of the world’s largest and best-known mining and metallurgical operations.
The DS automatic pressure filter is a totally enclosed design incorporating all polypropylene membrane plates on both sides of the chamber. The filter can be designed for inert operation using nitrogen for solvent-wetted processes or processes requiring a non-oxidizing atmosphere. Clean-in-place is a standard feature for most demanding standards of hygiene.
Filter technology after-sales services
Outotec is where its customers are. We serve our global clients through an extensive network of sales and service offices and representatives worldwide. Product engineering and manufacturing facilities are located in Finland and in Suzhou, China.
Fast open filter press
Outotec recently introduced the newest development for bulk material dewatering, the fast opening membrane filter press type FFP2512 with the biggest plate format ever designed. This design reduces the operation and maintenance cost and improves the productivity. Filtration capacity can reach more than 240t/h.
Horizontal vacuum belt filters
Models include open filters, enclosed designs and multi-purpose processing capabilities, including cake separation, washing, compression and thermal drying of the cake. An almost unlimited combination of options on a single machine makes Outotec one of the most versatile processing systems available.
Membrane filter presses
Membrane filter presses originally from Hoesch, now part of Outotec, have been installed in over 2,500 locations worldwide. Overhead beam and side bar designs are offered with a full range of options including automatic plate shifting, cloth discharge and cloth cleaning. Outotec specializes in corrosion-resistant designs for today’s challenging market requirements the polypropylene plates are standard for all designs.
Capillary action disc filters
Ceramec filters, now part of Outotec, are used to dewater mineral concentrates and pelletising feed slurries. The micro porous ceramic discs replace conventional filter cloth. Capillary action draws liquid through the pores, and only a small vacuum pump is required, resulting in significantly reduced energy consumption.
Vacuum disc and drum filters
Vacuum disc filters from Outotec have proved to be cost effective and maintenance friendly, serving the bulk mining industry successfully over 20 years. Vacuum drum filters are offered in several configurations, including belt or scraper discharge, pre-coat operation or top feed.
We offer polishing filters, which use adsorption filtration to remove and recover solids in low concentrations from process liquids. Adsorption filtration reduces solids concentrations in filtrates to parts per million with very low operating costs. There are no moving parts and cloth cleaning and solids discharge are carried out automatically.
