China Suppliers Factory Hot Melt Adhesive Steel Belt Pastillator for High-Quality Solid Pastilles Production
Product Video
Long Description
The steel belt pastillator operates by feeding molten hot melt adhesive onto a continuously moving, temperature-controlled steel belt. Through a calibrated drop forming system, the liquid adhesive is deposited in evenly spaced droplets, which are rapidly cooled and solidified as they travel along the belt. The result is uniform pastilles that are easy to handle, package, and re-melt when needed.
Hot melt adhesives present specific challenges in granulation: they are highly tacky, prone to stringing, and sensitive to temperature fluctuations. Excessive heat can degrade polymers or additives, while insufficient cooling causes sticking to the belt or incomplete solidification. The steel belt pastillator addresses these issues with precise temperature control along multiple cooling zones and a self-cleaning belt surface, ensuring consistent pastille release without adhesion.
With a production capacity ranging from 100 to 1600 kg/h, this system is suitable for both medium and large-scale manufacturing environments. Its flexibility allows it to process a wide range of adhesive formulations, maintaining product consistency while optimizing operational efficiency. In addition, the enclosed design minimizes contamination risks, improves workplace cleanliness, and supports stable continuous production with reduced maintenance requirements and enhanced energy efficiency for modern adhesive processing facilities.

Frequently Asked Questions (FAQ)
How does the steel belt pastillator process hot melt adhesives?
The system feeds molten hot melt adhesive onto a continuously moving, temperature-controlled steel belt. A calibrated drop forming system deposits the liquid adhesive in evenly spaced droplets, which are rapidly cooled and solidified as they travel along the belt, resulting in uniform pastilles.
What challenges in hot melt adhesive granulation does this system solve?
It addresses issues like high tackiness, stringing, and temperature sensitivity. By using precise temperature control across multiple cooling zones and a self-cleaning belt surface, the system prevents polymer degradation and sticking while ensuring consistent pastille release.
What is the production capacity of the steel belt pastillator?
The system features a production capacity ranging from 100 to 1600 kg/h, making it highly suitable for both medium-scale and large-scale manufacturing environments.
Why is a steel belt pastillator preferred over underwater granulation?
Unlike underwater granulation, the steel belt pastillator features no water contact (preventing moisture absorption), eliminates the need for energy-consuming drying systems, produces more uniform pastilles, reduces thermal stress, and generates no wastewater.
Is this system suitable for high-viscosity formulations?
Yes. The system offers high flexibility to process a wide range of adhesive formulations, making it exceptionally well-suited for high-viscosity and sensitive hot melt adhesive formulations.
