Rotary Vacuum Filter Priming?

Rotary Vacuum Filter Priming?

Rotary Vacuum Filter Priming?

(OP)
We have a rotary vacuum filter with a discharge roll cantilever to the filter drum.  There is a doctor blade that scraps the filter cake off the drum.  Some people in safety have raised concerns about the best way to coat the discharge roll initially.  My experience with filters of this type is that the operator must always scrape some dry cake off the filter drum and apply it to the discharge roll to build up cake and get the filter operating.  Safety is concerned that someone will get an arm caught between the drum and the roll.  I offered to install an emergency kill switch on a wire that the operator can simply touch that would stop the filter immediately.  Safety is still not completely satisfied although they liked this idea.  Anyone have any suggests on a different method of getting filter cake onto the roll initially?

RE: Rotary Vacuum Filter Priming?

hi, i really dont know which make of the  rotary filter   you  use coz we are using the alfa laval one and using   potato starch initially as a filter aid to the drum and and its working. it has not posed any problem as  the doctor blade is hidden completetely that someone cant trap  his hands .
thanks
