Advantage of Wear Resistant Plate
1,Prolong the service life of equipment, improve equipment utilization

High quality materials to ensure high service life of equipment, need not frequent production maintenance.

2, Increase production, improve quality

Avoid frequent starts for equipment that quality isn’t good, ensure equipment in good condition leading to high yields.

3,Reduce the labor intensity of workers, more secure

No frequent replacement of liner components, workers don’t have to deal with can occur at accident.

4,Improve equipment production efficiency, improve business efficiency

High utilization of equipment means high production efficiency and thereby the enterprise accrues economic


5,Wear-resisting life under the same operating conditions for Hardox400 board more than three times.
