  • Publication number: 20230128094
    Abstract: A reactor for coating particles includes a rotatable reactor assembly includes a reactor drum configured to hold a plurality of particles to be coated, an inlet tube, and an outlet tube. The drum includes a cylindrical tube, and an inlet-side endplate secured to cover an inlet-side opening of the cylindrical tube and/or an outlet-side endplate secured to cover an outlet-side opening of the cylindrical tube. A stationary gas inlet line is coupled to the inlet tube by a rotary inlet seal, a stationary gas outlet line is coupled to the outlet tube by a rotary outlet seal, and a motor rotates the rotatable reactor assembly. The inlet tube is releasably mechanically secured to the inlet-side endplate and the outlet tube is releasably mechanically secured to the outlet-side endplate.
