4.5 Sticking wear resistant ceramic chips to blade surface by Xianrun Blower

4. Improve the centrifugal fan blade wear resistance in cement plant

Ceramic material have the features of high wear resistance, high corrosion resistance, low density, low coefficient of friction, and high hardness. 

When the angle of attack is small, compared with metal and rubber, the ceramic wear is the smallest.

Sticking ceramic material to fan blade surface, 1.5 mm ceramic chips on easy to wear place on centrifugal fan impeller, is a very effective way to improve the wear resistance of the blade. 

What is more,the small ceramic chip thickness won't increase impeller quality much, so sticking wear resistant ceramic chips will not affect the impeller design strength and fan moment of inertia of startup.

It is worth noting that the expansion of the ceramic material and steel material difference is big, so the centrifugal fan working temperature should not be too high; must ensure adhesive combined strength, and prevent wear-resisting ceramics chips fall off during the working; ensure the blade surface is smooth without spray coating.
