The cement industry has taken a lot of technical measures to save energy and reduce the cost and carbon dioxide emissions. The domestic technologies are being used in small and medium-sized cement plant in China and many large cement plants are using imported technology. The limestone used in the domestic cement plant belongs to the moderate hardness. The new cement production line generally uses the single stage hammer crusher. The processing capacity of the crusher should be determined according to the scale of production, the annual operation days, working class system and other factors of the cement plants.
With the emergence of the large-sized vertical shaft hammer crusher with excellent performance, many new and expanded enterprises chose the vertical impact breaker with good tightness, large crushing ratio and small particle size to improve the yield of the
raw materials of the mill. Changes in products and ingredients include the mixing cement production and the use of the waste derived fuels, the production of limestone cement and the low alkali cement production and the use of slag in the kiln. The production of blended cement clinker includes one or more additives (fly ash, volcanic ash, blast furnace slag, silica fume) for grinding together. Energy saving and environmental development will be the future trend of the cement industry. As a result, the cement industry is trying to greatly reduce the energy consumption with new technologies.
