Mobile Thermal Drying Unit (Skid) for Sludge and Industrial Waste
The GRATT Mobile Thermal Drying Unit, also known as Thermal Drying Skid, is a compact, transportable and high-efficiency solution for reducing moisture in sludge and industrial waste.
Developed to meet growing demands for thermal drying in different segments, the unit allows you to drastically reduce the volume, weight and moisture content of waste, optimizing logistical costs and adding value to the treated material.
Its skid configuration guarantees mobility, quick installation and operational flexibility, making it ideal for tests, rentals or permanent applications in the field.
How does the GRATT Thermal Drying System Work?
The drying process occurs through indirect heating using steam, ensuring high thermal efficiency and quality of the final product.
The system operates as follows:
- The previously dehydrated sludge or residue is fed into the dryer;
- The material travels through the equipment while being continuously agitated;
- Heat is transferred by conduction across heated surfaces;
- Moisture is evaporated without direct contact with steam;
- The dry material is discharged at the end of the process.
This model guarantees precise thermal control, avoiding contamination and preserving the characteristics of the dry product.
Mobile Unit Configuration (Skid)!
The unit is supplied integrated, including all components necessary for operation:
- SVG model thermal dryer (e.g. SVG 5 for testing);
- Feed conveyor;
- Dry solids conveyor;
- Electrical control system;
- Evaporated gas treatment system.
The mobile testing unit has a capacity of up to 150 kg/h, with a minimum feed of approximately 20% total solids (TS).
Applications of the Thermal Drying System!
GRATT Drying Skid is widely used in:
- Sewage Treatment Stations (ETE);
- Water Treatment Plants (ETA);
- Paper and cellulose industries;
