Explore used, secondhand and surplus thermal disc dryers from IPP – in stock and engineered for high-efficiency heat transfer

IPP helps you save time and money with ready-to-ship disc dryers for wastewater treatment, chemicals and food byproducts

Thermal disc dryers use a series of heated, rotating discs mounted on a central shaft to indirectly dry sludge, slurries and other semi-solid materials. These systems provide efficient thermal contact between the material and the heat source, allowing for rapid evaporation without direct flame or high air volume. With over 47 years of experience, IPP offers secondhand and surplus disc dryers from 20 global process plant sites, backed by more than 15,000 in-stock equipment systems.

Disc dryers are often used in industries where thermal control, emission reduction, and minimal oxidation are key. Their compact design makes them space-efficient while delivering high throughput and energy savings.

Primary uses across industries

• In wastewater and sludge processing, they dry municipal and industrial sludges before incineration or disposal
• In chemical processing, they handle pigments, filter cakes and wet intermediates
• In agriculture and food, they process meat byproducts, pulp, grains and other high-moisture solids
• In mining and minerals, they dry fine ores and metal sludges

Types of materials processed

• High-moisture or viscous sludges and cakes
• Semi-solid pastes and slurries
• Sticky materials requiring slow, uniform drying

Common materials of construction

Thermal disc dryers are built for durability and consistent heat transfer:

• Carbon steel for general sludge and industrial waste applications
• Stainless steel for food, chemical and corrosive materials
• Special alloys for high-temperature or highly abrasive conditions

Key features of thermal disc dryers

• Indirect heating via steam or thermal oil
• Rotating discs maximize surface area for heat transfer
• Low dust and low oxygen environment
• Efficient solvent or moisture evaporation
• Minimal floor space with high throughput per footprint
