Coal ash is a kind of industrial waste slag, of which the emission of burning boiler of coal in thermal power plant. The way of using coal ash mill to grind the mixture of original ash and coarse coal ash to make it has some activity of hardness, which can produce the high performance concrete with high grade superfine ash. It can create more commercial benefit as well as complete utilization of coal ash.
Liming manufacturing the Ultrafine mill can grinding the coal ash for road building and filing.
The processed coal ash is used for the pavement base of road. The secondary limestone such as lime, coal ash and stone replacing the traditional increases the construction speed as well as lowering the investment cost. Now coal ash has been widely used as the embankment of highway with high quality when using the clay, which saves a lot of earth.
The coal ash used as filing material has a characteristic of large amount and direct usage. Its few investment and quick effect makes it as an important way for road building or filing. As soon as there is the ash truck for transportation and paving, grinding machine, the working can begin immediately with a large amount of quantity. Additionally, the requirement of ash is not strict as in barite or concrete no matter it is wet ash or dry ash.
According to coal ash’s own features, Liming concentrates its energy and successfully designs fine mill special for coal ash such as super large-sized grinding mill and strengthened superfine grinding mill, which grinding the original ash or coarse coal ash ejected from the coal burning electricity plant to meet the standard fineness. This increases the coal ash’s compound utilization as well as increasing the commercial benefits to achieve the total compound utilization of coal ash.
