Filter bags for cement plants, baghouse by baghouse.
A cement plant needs different filter bags in different baghouses because each one sees a different temperature and dust. Kiln and raw mill baghouses usually run P-84, fibreglass or PPS; coal mills need anti-static media; cement mills and packing plants run polyester. Cement is one of Masturlal's core industries, and its media is engineered to hold stack emissions at 5 mg/Nm³ or lower.
Media by baghouse
| Baghouse | Conditions | Media to evaluate |
|---|---|---|
| Kiln and raw mill (combined) | Hot, moist, alkaline dust | P-84, fibreglass with finish, or blends |
| Clinker cooler | Hot, very abrasive dust | Meta-aramid or fibreglass |
| Coal mill | Combustible coal dust | Anti-static polyester or anti-static aramid |
| Cement mill | Fine dust, moderate temperature | Polyester with ultra-microfibre surface |
| Packing plant | Ambient, fine dust | Polyester |
This is a starting point. The final choice depends on measured temperature, moisture, gas chemistry and the cleaning system.
Things that shorten bag life here
- Check acid dew point at the kiln baghouse: running below it corrodes cages and attacks the felt.
- Clinker cooler temperatures swing quickly; size the media for the peak, not the average.
- Coal mill baghouses need anti-static media and earthed cages.
What Masturlal supplies

Questions, answered.
Which filter bags are used in cement plants?
It depends on the baghouse. See the table above: each location has a different temperature and dust, so different media.
Does Masturlal supply plants outside India?
Yes. About 30–35% of turnover is exports, mainly to the Middle East, Bangladesh and Southeast Asia, with installations in 40+ countries.
