Wear Resistance Coal Steam Boiler Tube Protection Tube Erosion

Milling Plant | Газогенераторы МСД

Wear due to erosion is on account of the impingement of air streams laden with coal dust. It is higher at high velocity, particle size, and dust concentration. Grinding elements are naturally subject to maximum wear. Slow-speed mills are inher­ently superior for wear resistance.
