NOVELTY - Magnetic roll encapsulating material comprises graphene oxide, polyurethane, conductive agent, zinc oxide, accelerator, additives, anti-aging agents, ethanol, zinc powder, triphenyl phosphate, tricresyl phosphate, kaolin, glass beads, and talcum powder. USE - Magnetic roll encapsulating material. ADVANTAGE - The magnetic roll encapsulating material has very high carrier mobility, so even if the carrier density is very small, a certain conductivity is ensured, prevents the scouring of the ore particles from causing great wear on the magnetic roller, reduces the service life, and the wear resistance of the magnetic roller after the encapsulation is greatly improved.
