I’ll go first; in my unit, the original driving filter cloth was used for half a year at first； After replacing the filter cloth, the current maximum usage time is 1.5 months. Xinjiang Tianye
It mainly depends on what material is to be filtered; we use semi-aqueous slurries
Why was the OP’s first time so long
Ha, actually this is a false premise – the lifespan depends on the amount of filtering done, not on how much time passes
Haha, in the past we used versions with a validity period of 30 days, 20 days, or 15 days; occasionally it could reach 35 days. But now that we’ve switched to a new manufacturer, the validity period is generally around 50 days, with a maximum of up to 70 days.
It still depends on the slurry and the handling procedures; if the handling is improper, it may need to be replaced within three to five days
It mainly depends on management; with stricter environmental requirements, it can still be used for a long time. However, under more stringent environmental regulations, it needs to be replaced every 30 days. Vacuum filters are indeed a hassle; the moisture content in the filter cake is usually around 50%-60%. Now, many new projects are choosing centrifuges, as they are more stable than filter machines, require simpler operation, and are easier to maintain. In particular, the environment in the filter house has been **improved**.
Is the centrifuge stable? What is the moisture content of the filter cake after it is obtained? Which manufacturers are using it now?
About two months, with a maximum of three and a half months used at one time
