Hong Cheng vertical mill promote the application of carbide slag in the cement industry

    Human process, social development, environmental protection is a basic guarantee conditions and strategic task in the processing of modernization in nowadays; it is the primary task of sustainable development. In the processing of social development, environmental protection projects should also be focused, the national industrial policy is encouraging the full use of waste and scrap production of green building materials, thus reducing environmental pollution.

    Carbide slag is calcium carbide precipitate after hydrolysis, is solid waste as fly ash which can cause environment pollution.

    The main raw material of cement is limestone, which is mainly composed of CaO, the mass fraction of the cement industry limestone CaO containing 45% to 52%. Carbide slag is a product of the hydrolysis of calcium carbide, the main component of Ca (OH) 2 which accounting for about 70%, CaO content reaches up to 65%, so it can replace limestone to produce cement.

    So, What are the advantages of electricity carbide slag cement and fly ash made cement?

    (1) CaO content is high and fine particle size, improved raw material burn ability.

    (2) Carbide slag of Ca (OH) 2 decomposition temperature much lower than the decomposition temperature of limestone CaCO3, baking heat consumption is low.

    (3) The use of calcium carbide slag can reduce the amount of limestone and conserve resources.

    (4)electricity carbide slag as a raw material for cement production, not only to help companies save costs of waste treatment, but also can create new value, to become a new economic growth point in the future, with carbide slag as a raw material cement manufacturers will see this major opportunity, the real application of carbide slag will be expanded to the max.

    Traditional cement production, for the bulk of the wet material in cement industry 20 years ago, there is consensus: more than 10% of moisture in cement is the dead line of what grinding mill can do, now vertical mill is widely used which increase the data to 12% --14%.

    Currently in the processing of carbide slag cement production, changing the properties of carbide slag to adapt new dry method, vertical mill been invent by using characteristics of carbide slag; "grinding when dry and burning when wet" should be able to simplify the process, reduce capital investment and production costs, achieve better economic benefits.

    Guilin Hong Cheng is a professional advanced equipment of carbide slag, have advantages of energy efficient, smooth operation, low power consumption, big feeding size, easy product fineness regulation, small footprint, low dust, low operating cost and so on. The mill also adapt new roller seals, sealing performance is more reliable without blower sealed, further reducing the mill's oxygen content, explosion suppression performance is more excellent. As opposed to the traditional Raymond mill, the carbide slag mill is able to grind abrasive high hardness, high moisture, high fineness materials, its broad adaptability to achieve large-scale production of various kinds of materials is very important.
