Grinding machine for thermal paper coating slurry

online consultation

Product Highlights

  • High-precision double mechanical seal & discharge-screen structure — engineered for stable, leak-free operation under high-pressure grinding.
  • Grinding-chamber rotor structure: silicon-carbide inner barrel offers high wear resistance and excellent heat dissipation. The SiC ceramic chamber features ultra-high thermal conductivity and diamond-grade wear resistance — more than 5× that of alloy steel.

Additional Services:

  • Not only supply machines,But also offering technical support on how to  manufacture qualified coating slurry.
  • Thermal paper chemcial formulation support.
  • Themal paper coating process production support.
