Fly Ash Mill Equipment

Fly ash is the larger of China's current emissions of industrial waste residue, using them grinding mill used in cement mixing after treatment, mortar, fillers, bricks and others are currently the most promising ways of utilizing. At the present stage of China's annual industrial slag has already reached 30 million tons, with the development of power industry, coal-fired power plant fly ash emissions will increase every year. A large number of fly ash, if not addressed, it will generate dust, pollution of the atmosphere; if discharged into the river water can cause blockage of the toxic chemicals which will be on the human body and biological hazard. Therefore, based on conserving resources, reducing pollution, the handling of fly ash utilization has become a closely watched of the new area.

Based on the current mill technology development, large-scale ultra-fine milling machine has been able to achieve a one-time ultrafine materials processing, through the mill processed fine fly ash material, uniform particle size, surface activity improved, direct-doped added to the concrete can save a lot of cement raw materials, to improve the workability of concrete mixing materials, reinforced concrete plasticity and stability. Even on cement production enterprises in accordance with the ratio of 8% will be different species of fly ash blended cement clinker in the cement of finished products. At present the main use of fly ash used mill equipment has the following:

1, Vertical roller mill, referred to as vertical mill. Vertical roller mill is the use of large-scale roll system to realize high-volume grinding of materials handling equipment, as compared with ordinary mill's strengths lies in equipment and operation of large-scale automation. The usual vertical milling machine output could reach 100-500 tons per hour or more. Vertical grinding machine roller by a dedicated hydraulic system control, operation flexibility, ease of repair and maintenance. At present the domestic market, vertical mill grinding in a variety of energy-efficient high-yield production process for its overall performance has been far ahead of many milling machine, Raymond Mill equipment. "Using the vertical cement grinding mill is the future direction of development, instead of cement ball mill vertical grinding mill has proved its feasibility." Senior advisor of China Cement Net long-ming.

2, trapezoidal mill. Trapezium Mill has super Pressure Trapezium Grinder Mill, and the latest European trapezoidal Mill MTW. Trapezium Grinder Mill the traditional grinding roller and grinding ring are designed multi-level ladder shape, slow down the material in the grinding roller and grinding ring slipped between the speed of the extension of the RCC material time; high horizontal spring, the pressure is more strong, and greatly increased the fineness of the finished product and output. The latest high-technology components and a new concept of connecting components, reducing foreign matter on the extent of damage to the machine to ensure the security and stability of equipment operation results. Applies to Mohs hardness not higher than 9.3 and humidity below 6% of the mineral variety of non-flammable and explosive materials. 100-800 mesh materials usually yield between 20-50 tonnes of processing require the use of trapezoidal Mill better.

With the development and utilization of fly ash wide space for more on the technical level of the corresponding mill getting higher and higher requirements on the market of traditional Raymond Mill, ball mill can not meet to deal with industrial production capacity and fineness of the needs of a new type of vertical milling machine, milling machine with its trapezoidal latest technological achievements and to facilitate efficient use of the performance will become the mainstream equipment used in milling machines.
