FAQ

Q1: What is the hourly production capacity of this drying line?

A: The production capacity depends on the thickness, moisture content, and production line length of the insulation felt. Customized solutions can be provided according to specific production requirements.

Q2: How does the equipment ensure uniform thickness of insulation felt after drying?

A: The equipment adopts balanced upper and lower hot air convection technology. The tension of the conveyor mesh belt is adjustable to effectively prevent material warping, lifting, or uneven thickness after drying.

Q3: What heating energy sources can be used for this equipment?

A: The system supports multiple heating methods, including electric heating, natural gas, steam, and thermal oil heating. Users can select the most suitable energy source according to local energy costs and production conditions.

Q4: Is daily maintenance of the equipment complicated?

A: No. Daily maintenance mainly includes regularly cleaning the moisture exhaust ducts, checking the transmission chain system, and lubricating bearings to ensure stable operation.

Q5: Can special materials such as aerogel insulation felt be processed?

A: Yes. The system features low-speed stable conveying and precise temperature control, making it highly suitable for drying and curing special insulation materials such as aerogel felt.
