Advantages of quality wear resistant magnetic liner: 1, Long Life: working principle surface adsorption layer of magnetic iron powder liner and crushed the ball to form a protective layer, so that the liner surface from direct wear and tear, so that the liner to extend the life of more than eight times the original. 2, Quality of light, thin: only 70% of the weight of the magnetic liner manganese steel liner, trouble-free, no less bolted, the job rate, reduce labor intensity. 3, good work environment: noise, sound effects protective layer, mechanical noise than manganese steel liner to reduce noise 12-15dB, magnetic liner mechanical noise is 68dB-95dB, no leakage pulp. 4, Installation handy shortcut: long need to replace the liner, not less bolt, run zero defects, zero maintenance, improve operating rate of more than 5%.
