Belt Dryer/ Band Filter - Belt Filter

Horizontal Belt Filters are, in broad terms,the most commonly used vacuum filters in the industry due to their flexibility of operation,adaptation to corrosive slurries and suitability to handle large throughputs.
The development of the Horizontal Belt Filters for the chemical process industries was closely associated with the progress in rubber technology since they incorporate an endless and thick rubber belt of a complex design to support the cake retained by the filter cloth.

The first known filters were the Lands Rona and Lurgi built in the 20's and the Georgina which was a belt filter but with attached trays. The belts were very narrow and short, with a 30 cm wide by 4-5 meters length, and were primarily applied to the washing of phosphate rock. Later, being top feed filters that facilitated multi-washing stages, they were applied in phosphoric acid plants to replace the chains of 3 or 4 internal feed rubber covered Drum Filters used for gypsum washing. As the demand for area has gone up filters were manufactured with three and four 30 cm wide belts running in parallel since the rubber manufacturers were unable to catch-up with the growth of the chemical plants. For this reason the main rivals over the years to belt filters were the Tilting Pan and Table Filters so when rubber belts were the constraint to filtration area growth these filters were in demand and vice versa. Nowadays it is high time for belt filters since rubber technology has made a big step forwards in the past 10 years. Belts 4 meter wide for 120 m2 filters weigh more than 10 ton and are manufactured in one piece from sophisticated rubber compounds. 

Belt speed is another parameter that sets forth a race among the designers of filters since for many applications a short cycle time is essential. The constraining factor on belt speed is purely mechanical and depends largely on the supporting method of the heavy belt with its cake on it. Belt filters are the fastest filters available today and the speed of modern filters can reach over 50 m/min and yield very short cycle times

A filtrate manifold collects the mother and wash liquids to one or more vacuum receivers. It should be kept in mind that a short path of filtrate between the vacuum box and the receivers reduces to a minimum the losses of vacuum for both the single phase flow of the mother filtrate and the two phase flow of air and wash filtrates
