Three Roller Coating Machine


DaswellPowder three-roller coating machine enables continuous, dust-free surface modification for powder surface treatment.

It is widely used in plastics, masterbatch, paints, inks, and rubber industries. These industries need stable coating quality and high surface activation.

The three roller coating machine is mainly used for surface modification of mineral powders. You can use it for coating your calcium carbonate, talc, and some other industrial fillers. It can apply coating agents evenly onto powder particles, significantly enhancing the powder dispersion, hydrophobicity, and compatibility with polymers, rubber, and coating systems.

Working Principle

The three roller coating machine operates by a continuous and fully automated powder surface modification process.

There is a double screw feeding unit to feed powder materials, which is stored in the silo after grinding and classifying, into the coating machine. And the coating agents will be sent into the machine after measuring. If your coating agents are solid, there is a temperature-controlled heating system for melting the agents into liquid form.

There are three rotating rollers inside the coating machine. Powder and modifier enter the fister chamber in sequence. Inside the chambers, a high-speed rotor generates strong airflow, impact, shear, and vortex mixing. The powder particles and coating agent disperse evenly and interact fully.

During this process, the coating agent is uniformly spread and firmly attached to the powder surface. It can achieve effective surface modification and stable coating performance.

Features

Low energy consumption

It utilizes heat generated by high-speed rotor-stator friction. This not only eliminates external heating but also reduces investment and operating costs.

High-efficiency continuous production

It is designed for stable 24/7 operation with a large output. For your industrial scale powder coating requirement, this machine three roller coating machine is suitable.

Precise dosing and high coating rate

We have a metering pump for measuring the modifier precisely. You can control the powder-to-modifier ratio accurately. This ensures low modifier consumption and uniform, high-quality coating.

Advanced vortex mixing without particle damage

Cold powder and hot agent vortex mixing achieves high modification efficiency while maintaining the original powder shape.
