Energy Saving Methods of Cement Ball Mill

In view of cement ball mill system energy conservation problems, should reform from the following two aspects:
1. Use advanced grinding equipment to achieve energy-saving. China's domestic vertical grinding mill, roller presses have advantages with high yield, energy consumption (power consumption, small metal consumption), raw materials, cement and slag grinding system is current widely used methods. Relative to the ordinary ball mill system, vertical mill, roller press can generally increase production 80% ~ l20%, saving about 30%, enterprises through the increase efficiency in order to achieve energy efficiency. Hefei Institute of vertical grinding mill, roller press system has been able to meet the 6000t / d clinker production line supporting the use of scale, according to the system to select the appropriate equipment and technology. If you consider a one-time investment in the enterprise, the existing open ball mill system, the ordinary ball mill can be transformed into a screening function of high-fine high-yield mill (only for grinding mill internal body and grinding body transformation), production and energy saving are generally about 30%. In addition, the usage of high-yield fine grinding of cement characteristics, but also by mixing more than 5% to 10% of the purpose of energy conservation. On the closed circuit system, you can consider the supporting situation to consider the equipment update, such as the original centrifugal separator replacement for the structure of the principle of more advanced efficient powder or efficient combination of powder, can reach energy saving more than 30%.
2. Reduce production costs by increasing the utilization of waste. Now mature methods are: slag, steel slag, fly ash and other waste, after grinding to 400m2 / kg ~ 600m2 / kg above the specific surface area, the mixture can be increased to more than 30%, with carbide slag preparation raw materials, the maximum amount of up to 60%; In addition, the usage of garbage calcined raw material production cement is not a grinding category, but it is the direction of energy-saving cement production, full use of waste calcination technology is now in some cement plant test line ignition success, can make all the garbage and ash are used, not only low pollution emissions, is conducive to grinding, but also at least 30% to 40% of the traditional high-resource fuel production costs.

Cement ball mill saving energy system is actually a systematic project, such as, raw material selection, ingredients, calcination equipment and process, etc., may have an impact on the grinding, and should be combined with the conditions of enterprises to consider.
