Coal washing sludge

Filter cloth and filter plates for coal fines dewatering

Coal washing sludge can cause cloth blinding, difficult cake release and repeated maintenance. DOFIL checks the slurry, existing cloth, plate type and washing frequency before recommending replacement cloth, plates or a press package.

Common coal washing filtration problems

Coal fines, clay content and cycle frequency make cloth selection more important than catalog fabric names. Buyers normally compare cake release, washing interval, filtrate clarity and cloth life.

Cloth blinding

Permeability, filament type and finishing are checked against the particle condition.

Wet cake

Press pressure, membrane squeezing and flocculant dosing can be reviewed together.

Frequent replacement

Samples and old cloth photos help repeat supply stay consistent.
