Rotary Coating Machine & Automatic Coating Systems

From Versatile Application to Precision-Controlled Coating Processes

The Rotary Coating Machine is the versatile and efficient core unit for applying liquid coatings to fertilizer granules. Building upon this robust foundation, our Automatic Coating Systems integrate precision dosing, programmable logic control (PLC), and full process automation to transform the basic coating operation into a repeatable, high-efficiency, and waste-minimizing value-adding station. Whether you need a reliable standalone machine or a turnkey automated solution, we provide the technology to ensure uniform coverage, reduced costs, and superior product quality.

Key Features

  • Core Coating Unit

    A gently rotating drum with a cascading action ensures even exposure of all granule surfaces to the coating agent.

  • Precision Spray System

    Finely atomizing nozzles with manual or automated, recipe-controlled dosing pumps for consistent liquid film application.

  • Automation & Control – For Systems

    PLC-based control with a touchscreen HMI allows for storing and recalling multiple coating recipes, automating the entire cycle (feed, coat, discharge), and enabling closed-loop control based on real-time feed rate data.

  • Integrated Design & Cleanliness

    From simple access doors to complete dust collection integration and automated cleaning cycles (CIP options) in system configurations.

  • Heating Capability (Optional)

    Integrated warm air flow or jacketed heating for coatings requiring reduced viscosity or faster drying.

Advantages

  • Superior Coating Uniformity

    Achieves a consistent layer on every granule, with automated systems guaranteeing batch-to-batch repeatability.

  • Significant Raw Material Savings

    Precision automated dosing eliminates over-application, typically reducing coating agent consumption by 10-25% compared to manual operation.

  • Enhanced Product Value & Consistency

    Effectively prevents caking and dust, producing a premium, free-flowing product. Automation removes human error, ensuring every batch meets exact specifications.

  • Reduced Operational Cost & Labor

    Simple mechanical operation provides low cost. Automated systems drastically reduce operator involvement and lower overall cost per ton coated.

  • Flexible Integration

    Easily fits into existing lines. Automated systems are supplied as pre-engineered skids for seamless integration into new or upgraded plants.

Applicable Raw Materials

  • Anti-Caking Agents

    Mineral oils, surfactants

  • Dust Suppressants

    Various oils and polymers

  • Polymer Coatings

    For basic controlled-release or moisture barriers

  • Colorants & Dyes

    For product identification and branding

  • Microbial & Additive Slurries

    For coating with beneficial agents
