Vacuum belt filter

Separating solids from a slurry is a common industrial process in industries from mining to pharmaceutical production.  Vacuum belt filtration is used successfully in all of these industries due to its simple mechanical design, excellent process control, even and consistent results, and efficient filtration.  With this technology, the filter cloths are continually cleaned as they cycle through the machine and so are always ready to get the job done.

Continuous filtration tailored to your process and your needs

Tefsa offers a line of vacuum belt filters that can be configured to meet the needs of almost any industrial process that requires filtration.  Many options exist for filter media, cake washing, cake discharge, and unit capacity. Construction materials can also be selected to suit the operation environment and substances to be processed.  Process variables can be adjusted to achieve almost any desired separation results.  Belt travel speed, applied vacuum pressure, load level, cake washing quality, and cake drying time can all be adjusted to meet the needs of your particular process.

The units are of a simple, mechanical operation and and occupy a minimized foot print.  Periodic maintenance and cleaning are simple and quick processes.  Filter cloths can be supported on either a rubber belt or a trays system to which the vacuum is applied.  The vacuum belt system is ideal for larger applications such as those in the mining industry.  It is an extremely robust and durable system.  The vacuum trays system which typically consists of stainless steel belts supporting the filter cloth is best suited to smaller units and to those with filtrates that are corrosive.  It is also preferred in situations where simplified or light-weight installations are needed.
