How to Increase the Production and Quality of Ball Mill

In general, to increase the ball mill output has three kinds of direct channels:
1. Home before the fine grinding machine;
2. To improve the grinding system to improve the grinding efficiency;
3. Increase home efficiency separator.
The above-mentioned three kinds of methods, any one kinds of ball mill can be substantial increase in production. Of course, if the plant if conditions permit, the above-mentioned three kinds of methods of supporting the use of the best effects, which is grinding system at home and abroad in recent years the general trend of the design. The relationship between the three: chronology is the premise of the former mill, flour mill is to ensure that after the election, is the fundamental transformation of grinding inside. Made before the fine grinding of materials into the ground significantly reduced size, which reduces the load on grinding system; Separator efficiency, the most direct benefit is the maximum fine to be finished in time to elect to reduce the rate of cement powder to finished product, ball mill to reduce the load; and weary with the transformation, which is grinding system improvements, is the most fundamental solution to the problem. Into the mill reduced the particle size of materials, separator efficiency, and less efficient if the grinding system, the impact of the ball mill is not only the production but also affect the quality of cement.
The quality of cement, from the grinding process is broken and the mill and the election before the powder is not directly related to efficiency. China's quality inspection of concrete indicators are generally two: cement sieve and the residual value of specific surface area. However, in recent years of international quality indicators cement is cement particle size distribution, and the target screen than the residual value of the cement surface area and better reflect the real situation of the quality of cement. This has given rise to cement workers in our country seriously. In general, the cement particles, the particles smaller than 3μm faster hydration is not conducive to long-term strength of cement, it is recommended no more than 10%; 65μm particles larger than the basic non-activity, not the best; 16-24μm particle activity of the highest . Some add in the production of cement limestone. There is no activity of limestone, is simply a filler, but it can improve the cement particle size distribution of finished products.
After the implementation of new standards for cement, cement Screen residual value of this indicator has little practical significance. New standards for some to pay more attention to the specific surface area, and particle size distribution for cement are no specific requirements.
The significance of the implementation of new standards is the need to substantially improve the quality of cement products, and further speed up the elimination of the significance of the backward, the promotion of competition in the market, with the international cement standards for China's accession to the WTO after the cement industry to prepare for integration into the international market. As a result, China's cement plant, in particular small and medium-sized cement plant how to improve the quantity and quality of cement, it becomes an issue.
As the professional manufacturer of complete sets of mining machinery, such as Cement production line,cone crusher,Stone production line,Sand washing plant,Rotary dryers, Henan Hongxing is always doing the best in products and service.
