Collecting plate are important for efficiency and long-term reliable operation. collecting electrode incorporates our traditional Optimum Precipitation Zone Electrode design that provides quiescent zones to aid in particulate collection and to reduce re-entrainment during rapping. This assembly has also been found to be very dynamically responsive during rapping, allowing collected materials to be dislodged without excessive force. The collecting plates are periodically rapped by mechanical rappers to dislodge dust, which then drop into hopper below. It takes between 0.01 and 0.1 second for dust particles to acquire a change in the corona region. It is capable to remove particale size .01-10 microne ane clean efficeiency nearly 90%. Its available in different grade like IS152 grade D.
