Power plant pulverizing system wear resistance has all appeared a scollision, friction, and impact, coal pulverizing system equipment was badly worn due to high speed pulverized coal stream, especially for the mill outlet pipe, a wind pipe bend, powder separator.

Each power plant all know it is essential to study and understand the pulverized coal preparation system, especially coal grinding mills, they have taken different measures against abrasive wear.

1.GJ - 199 series wear resistant daub: its wear-resisting performance is superior to steel plate,and has a good cohesiveness and strength,but has too many shortcomings ,such as construction difficulty is great, and high cost.
2.Wear resistant casting: wear resistance is better than steel plate, but too heavy and has high brittleness, access to system load safety system is restricted, and easy to break during installation. The equipment circulation section will be decreased due to big volume itself,  also increase the degree of wear.

chromium carbide overlay plate has been widely applied in middle storage powder system, and has gained remarkable economic benefits. Its service lifetime is much longer than wear resistant daub and wear resistant casting, hardfacing plate from YAOYU has excellent wear resistance ability and hardfacing layer will not peel off during work, also has good development prospect.
