Fly Ash Processing Technology

Fly ash mill system can be divided into two systems. First, the coal ash sorting system, qualified coal and large particles in coal will be separated; Second, the grinding system, to process large particles to get the granularity of qualified coal.

Fly Ash Processing Plant

Generally, a jaw crusher or a cone crusher is used. In some non-metallic ore or cement industries, when processing medium or hard or soft ore, an impact crusher can also be used.

Fly Ash Processing Technology

For the low content of total iron in the raw fly ash slag, it should be pre-selected and enriched first. The pre-selected equipment can be a hydrocyclone or a wheel-type sand mixer. For example, in a thermal power plant, because the magnetite has a large proportion to the original ash, after the preselection of the cyclone, the total iron in the fly ash slag from the sand discharge port is enriched.

Its all-iron grade increased from 13.91% to 20.84%, and the recovery rate of all-iron was 65.91%. The all-iron-enriched fly ash slag was sorted by a cylindrical weak magnetic concentrator, and the obtained iron concentrate had an all-iron grade of 45.22. % And the recovery rate was 39.17%.
