fly ashFly 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. Therefore, based on based on conserving resources and reducing pollution, handling and utilizing the fly ash has become a newly and closely concerned area. Currently the most promising ways of utilizing fly ash is to grind them by grinding mills, then applied them to cement mixing, mortar, fillers, bricks making and others.

Based on the current mill technology development, large-scale ultra-fine milling machine has been able to achieve a one-time ultrafine materials processing. The fine fly ash materials being processed through the mills are with uniform particle size and with improved surface activity. If added to the concretes directly they will save a lot of cement raw materials and also, they will improve the workability of concrete mixing materials and improve the plasticity and stability of reinforced concretes. Even in some cement production enterprises, people blend fly ash, in accordance with the ratio of 8%, into different cement clinkers to make cement products.

At present the main mill equipment to process fly ash include the following ones:

Trapezium Grinding Mill. The traditional grinding roller and grinding ring are designed multi-level ladder shape in the Trapezium grinding mill, which slows down the dropping speed of the materials between the grinding rollers and grinding rings and extends the grinding time to the materials; the pressure is more strong because the high pressure springs placed horizontally, which increases the fineness of the final products and the output. It usually performances better to produce 100-800 mesh powder with a capacity of 20-50 tons per hour.
