Real samples. Before and after our dryer.
Sludge, pigments, salts and minerals dried on AS Engineers paddle dryers.
Inside the dryer
From sticky cake to dry granules
One continuous pass. Four visible changes.
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.

Pilot trial
See your own sludge dry before you invest
We run your material on our 25 kg/hr pilot dryer – at your site or at our Ahmedabad works – and hand you real numbers: drying rate, final moisture and product form. The trial is paid, and we waive the fee when you place your order.
Tell us your sludge. We will size your paddle dryer.
Share quantity and moisture – get a technical proposal, payback estimate and pilot-trial option within one working day.
