Centrifugal fan is an important auxiliary equipment in cement production.
In general, they are gas-solid two phase flow centrifugal fan in cement industry, such as ID fan of dust removal system, FD fan of pneumatic conveying system. This is to say, the working medium of this centrifugal fan often contains a certain amount sizes and shapes of solid particles.

Because the centrifugal fan works under dusty gas flow, the dust particle in air flow not only cause wear and tear on the fan impeller, but also adhere and gather ash deposition. What is more, the wear and ash deposition are uneven, destroying the fan rotor balance; causing centrifugal fan vibration; reducing the service life. In that case, the centrifugal fan can not work normally.

So, it is necessary to take corresponding measures to impeller wear in cement industry.
