Filtration Performance with High-Efficiency Drum Filters

The capacity of vacuum rotary drum filters varies widely,depending on the material and its water content.Rough calculations often assume a capacity of 1,000lb.per square foot per 24hours,although modern conditions usually exceed this figure.The moisture content in the discharged cake typically ranges from 8to 12%.Rotary drum filters are compared with rotary disk filters.Drum filters are particularly suitable for handling coarse or granular material,as their porous cake structure makes filtering rapid.They are less suitable for products with much slime,which doesn't filter as readily.Drum filters require a longer operation for cloth replacement compared to rotary disk filters,but the wire winding around the drum protects the fabric from extensive damage.The installation of a rotary filter system is detailed,highlighting the need for a dry vacuum pump and a moisture trap to prevent water from entering the pump cylinder.The vacuum pump usually used is of the reciprocating type with inte…
