Product Overview
Our Laboratory Powder Spray Coating System represents the pinnacle
of precision coating technology, specifically engineered for
R&D and small-scale production of coated granules. This
advanced integrated system combines powder spray coating and
granules polishing in a single, compact unit, enabling researchers
and manufacturers to develop perfect coating formulations and
achieve commercial-quality finish at laboratory scale. Utilizing
innovative electrostatic powder spray technology and gentle
mechanical polishing, this machine provides unprecedented control
over coating thickness, uniformity, and surface characteristics -
making it an indispensable tool for pharmaceutical, fertilizer,
food, and chemical industries.

Working Principle
Granular material is fed continuously or in batches into a rotating
drum. As the drum rotates, an internal lifting mechanism gently
picks up and dumps the granules, forming a uniform "granule bed."
Precision spray guns atomize the coating solution (such as polymer
resin, sulfur, syrup, etc.) and evenly distribute it over the
tumbling granules. Simultaneously, heated air passes through the
drum, rapidly drying the coating solution upon contact with each
granule. This process forms a strong, continuous film around the
granules. Finally, the coated granules are discharged for further
cooling or packaging.

Primary Applications
This versatile coating machine is ideal for a wide range of coating
applications on granules and pellets, including:
Slow-Release & Controlled-Release Urea Fertilizers: Coating with
polymer-based membranes to delay nutrient release.
Sulfur-Coated Urea (SCU): Applying a uniform layer of molten sulfur
onto urea granules.
Urea with Micronutrients: Coating granules with essential trace
elements like Zinc, Boron, etc.
Anti-Caking Agent Coating: Applying anti-caking powders or liquids
to improve storage and flowability.
Other Applications: Seed coating, pesticide granule coating, and
coating for various chemical and food products.
