    摘要: A plant for producing cement, having a first stage for crushing raw material to form raw powder, a second stage for calcination and sintering of the raw powder to form cement clinker, a third stage for cooling the sintered cement clinker, and a fourth stage for crushing the sintered cement clinker to form cement. The first stage for crushing raw material to form raw powder and the fourth stage for crushing the sintered cement clinker to form cement are structurally combined. In this way, during servicing or repair of one crushing stage, the plant need not be shut down because, y variable circuitry switching, the crushing stages permit plant operation with reduced production output.

    摘要: [PROBLEMS] To effectively utilize coal ash while lowering the concentration of mercury in a gas discharged from a cement kiln. [MEANS FOR SOLVING PROBLEMS] Coal ash from a thermal power plant or the like is received by a system for producing cement. The received coal ash is divided into ash and unburnt carbon. The ash thus divided is utilized as a material for cement in the system for producing cement, while the unburnt carbon thus divided is utilized in the system for producing cement depending on the concentration of mercury in a gas discharged from a cement kiln of the system for producing cement. In the case where gags discharged from the cement kiln of the system for producing cement contains mercury at a high concentration, it is possible that the unburnt carbon in the coal ash, which contains mercury localized therein, is not fed into the system for producing cement but processed outside the system for producing cement or the unburnt carbon is fed in a controlled amount into the system for producing cement. Mercury is removed form the thus separated unburnt carbon and the unburnt carbon, from which mercury has been removed, can be used as a fuel in the system for producing cement.

    摘要: A cement clinker which necessitates no considerable change in the main chemical components and mineral components of cement, is free from preheater coating problems and adverse influences on cement properties, and is effective in reducing the heat quantity required for burning; and a process for producing the cement clinker. In the process for cement clinker production, a substance having a melting point higher than the temperature of a liquid phase of the cement clinker and serving as crystal nuclei for C 3 S is incorporated include a fine powder of refractory brick, particles of an ordinary Portland cement clinker, a fine powder of a high-early-strength Portland cement clinker, a high-early-strength Portland cement, and a fine powder of quicklime. Due to this, alite generation is accelerated even at a low temperature. As a result, high-quality clinker can be produced through burning using a small unit heat quantity and no decrease in cement quality results. The process contributes to a reduction in preheater coating amount and prolongation of the life of the refractory bricks.
