The energy saving measures of
cement ball mill are to follow
The use of advanced grinding process equipment to realize energy saving
Domestic vertical mill, roller press in our country has a high output, power consumption (power consumption), metal consumption of small advantages, such as raw material, cement and slag grinding system USES more methods. Compared with the ordinary ball mill system, vertical mill, roller press general could increase 80% ~ l20 %, power saving 30%, enterprise by increasing efficiency and energy saving. Hefei institute of vertical mill, roller press system has been able to meet with 6000 t/d clinker production line, can choose the corresponding equipment and process based on the system. If you consider the one-time investment of enterprises, the existing open flow ball mill system, can transform the ordinary ball mill for grinding high yield with functions of screening high thin (only for internal grinding machine grinding body modification), the output power saving generally can reach 30%. In addition, the advantage of the characteristics of high yield and high fine grinding cement, can also be through the mixed materials 5% ~ 5% more to achieve the purpose of energy saving. For closed-circuit system, visual its form a complete set of equipment update, such as centrifugal separator can replace for the structure principle of the original more advanced efficient classifier or efficient combined classifier, electricity production also can achieve 30% above.
By increasing the utilization of waste residue to reduce production costs
Slag, steel slag and fly ash slag, after fine grinding to more than 400 m2 / m2 / kg to 600 kg of specific surface area, can make its mixed material content increased to 30% above, prepared with carbide slag slurry, the maximum content of up to 60%; In addition, the waste of calcining cement raw meal production not belongs to the category of grinding, but it is the direction of the cement production and energy saving, fully using the garbage burning technology is now in some cement plant test facilities successfully ignited, and ash can make garbage all be used, low emissions, not only is advantageous to the grinding, also can be reduced by at least 30% ~ 40% of the resources of traditional high fuel costs of production.
