subject: How To Improve Cement Mill Production [print this page] A. Set the fine crusher in front of the mill;A. Set the fine crusher in front of the mill;
Two. Improved grinding system, to improve the grinding efficiency;
3. Plus set a high efficiency separator.
The three methods mentioned above, any one kinds can greatly improve the yield of the ball mill. Of course, if the factory conditions permitting, the three kinds of methods supporting the use of the most satisfactory, the major trend of the past few years grinding system at home and abroad. The three relationships: the crushing mill before the premise of the powder, after grinding to ensure transformation of the mill is the fundamental. Before crushing mill makes into the grinding material particle size greatly reduced, thereby reducing the load of the grinding system; separator efficiency, the most direct benefit is the finished powder to maximize the timely elected to reduce the cement the finished product back to the powder rate, reduce the mill load; and the transformation of the mill is grinding system improvements, is the most fundamental solution. Particle size reduces into the mill, separator efficiency grinding system less efficient, and affect not only the mill's production, but also affect the quality of the cement.
1.2 cement quality problems
The quality of the cement, single from the grinding process, crushing and grinding and classifying efficiency is not directly related. China's cement quality testing indicators are generally 2: cement sieve residual value and the specific surface area. But in recent years the international indicators of the quality of the cement test the cement particle size distribution, this indicator sieve residual value than concrete and specific surface area to better reflect the real situation of the quality of cement. This has caused considerable attention in China's cement workers. Generally speaking, cement particles, less than 3 m particle hydration quickly is not conducive to long-term strength of the cement, the proposal does not exceed 10%; particles larger than 65m almost no activity, it is best not; 16-24m particle activity . Some cement plants in production adding limestone.Limestone is no activity is purely a filler, but it can improve the particle size distribution of cement products.
After the implementation of the new cement standard, the practical significance of the residual value of this index for cement sieve. New standards for the specific surface area pay more attention, but there is no specific requirements for the cement particle size distribution.
Second, our task
The significance of implementing the new standards is the need to substantially improve the quality of cement products, further significance is to speed up the elimination of backwardness, to promote market competition, with the international cement standard practice to prepare for the cement industry into the international market after China's accession to wto. As a result, China's cement plants, especially small and medium-sized cement plants how to improve the yield and quality of cement, has become an urgent problem.
With its high quality products such as Rock crusher, Sand washing plant, Rotary kiln, Cone crusher, Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
