Flue gas from coal combustion in after the collected down fine ash fly ash. hammer mill is the use of the principle of the vibration motor excitation, the material as the transport type jump motion on the screen. The device is applicable to 0.74-10mm, water content less than 7%, non sticky materials of any dry material screening, can be used as the ash with hammer mill to special processing of fly ash, in order to achieve the effect of repeated recycling resources. 

The hammer mill is mainly used for abrasive abrasive materials, chemical, mining, medicine, metallurgy, building material, food, chemical and other industries in the dry powdery, granular or fine powder materials screening.The fly ash with hammer mill can also be used as mixing vibration sieve used for the processing of asphalt in road construction etc.. 

In the production process, the material from the feeder evenly into the charging sifter mouth, sieve, produced a number of specifications through multi-layer screen material, respectively, from the respective outlet. In the fly ash in the processing process, because the fly ash particle size smaller and better mobility, so the screening effect is better, the fly ash into the vibration screen center, trajectory flow on the screen to bounce up and down and in accordance with the hammer phase angle is produced, coarse powder and fine powder is automatically separated and rotated to the discharge port.
