The challenge
The Pulp and Paper drying problem
- ✕Large volumes of wet fibrous sludge every day
- ✕Landfill and haulage costs keep rising
- ✕Fibre bridges and sticks in ordinary dryers
With an AS Engineers paddle dryer
Paper mills generate large volumes of fibrous, high-moisture sludge with useful calorific value.
Why a paddle dryer fits
- Fibrous sludge handled without bridging
- Dry sludge suited to boiler co-firing
- Large reduction in weight sent for disposal
- Uses mill steam – low added utility cost
Typical process
Pressed sludge is screw-fed into the dryer; dried material goes to the boiler fuel yard.

Inside the dryer
From sticky cake to dry granules – one continuous pass
Wet cake
Dark, heavy, sticky lumps enter the hopper.
Plastic phase
Heat softens it; paddles knead and stretch.
Shearing phase
Paddles shear the mass into crumbs.
Dry granules + powder
Free-flowing granules and fines discharge.
Illustrative moisture along the dryer. Dried output goes to fuel · cement kilns · bricks · agriculture.
