Grinding machine for thermal paper coating slurry
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.
