Fly Ash Introduction

Fly ash is one of the residues generated in combustion, and comprises the fine particles that rise with the flue gases. Ash which does not rise is termed bottom ash. In an industrial context, fly ash usually refers to ash produced during combustion of coal. Fly ash is generally captured from the chimneys of coal-fired power plants, and together with bottom ash removed from the bottom of the furnace is in this case jointly known as coal ash. Depending upon the source and makeup of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous and crystalline) and calcium oxide (CaO), both being endemic ingredients in many coal-bearing rock strata.

In the past, fly ash was generally released into the atmosphere, but pollution control equipment mandated in recent decades now require that it be captured prior to release. In the US, fly ash is generally stored at coal power plants or placed in landfills. About 43 percent is recycled, often used to supplement Portland cement in concrete production. Some have expressed health concerns about this.

Fly Ash Grinding Mill

fly ash is one of largest emissions of the industrial waste residues in current China. Nowadays, the yearly industrial slags have reached 30 million tons, and with the development of power industry, the emissions of fly ash from coal-fired power factories will increase year by year. A large number of unprocessed fly ash will generate dust and pollute the atmosphere; if discharged into the water system, the fly ash can cause the rivers blockage and the toxic chemicals contained in it will be harmful to the human body and life-forms.

The first one is vertical mill machines short for vertical mill.Vertical mill uses large-scale roll system to grind high-volume materials. Compared with ordinary mill, its strength lies in large-scale equipment and operating automation. The output capacity of the usual vertical mills can be up to 100-500 tons per hour or more.The rollers of the Vertical mills are controlled by a special hydraulic system so the operation is flexible and convenient and the repair and maintenace is very easy. At present in the domestic market, vertical mill has been far ahead of many other grinding mills and Raymond mill equipment in a vary grinding processes because of its comprehensive performance of high-yield and energy-effient.

Fly Ash Grinding Mill Application

Grinding Mill production of fly ash, used for new building materials market prospects with the following:

1. The state ban on the production of clay bricks, construction of energy-saving residential block for the production of fly ash to create a golden opportunity. 170 State Office had asked the city wall reform limited ban on the use of clay bricks, which means that 170 city building wall materials will need to be replaced by the new wall materials. It can be said that this is a revolution in the history of Chinese architecture. Minister of the Ministry of Construction Order No. 76 to require new or expansion projects must design and construction of building energy efficiency standards, shall not use solid clay brick. This, undoubtedly, the development of new wall materials, paving the way, this huge market share is bound to bring great insight to entrepreneurs and economic benefits.
