Advantages introduction

1. Low energy consumption: the density of special grinding body for dry-type cement mill is about 3.65g/cm3, and the density of high winding steel ball is about 7.8g/cm3; the total weight of special grinding body for dry-type cement mill with the same volume will be doubled compared with the traditional grinding body, the current of main machine will be reduced, and the temperature rise will be reduced accordingly; at the same time, due to its light weight, the filling rate of the mill can be increased moderately, and the grinding efficiency will be improved. The production time It is improved, thus further reducing the unit power consumption (power saving ≥ 20%).
2. Low temperature: the special ceramic grinding body of cement dry mill is made of inorganic material. In the grinding process, its heat is very small, no static electricity is generated, the temperature is low, and the fluidity of cement in the mill is accelerated (the temperature of cement out of the mill is reduced by more than 20%).
3. Low maintenance cost: after using the special grinding body of cement dry mill, the temperature in the mill is low. In addition, the weight of the mill is light, the overall impact force of the mill is small, and the neutralization loss of the grinding body in the mill is reduced. At the same time, the overall damage of the equipment in the mill, the grinding head and the corresponding supporting facilities at the grinding tail is reduced, the maintenance cycle is extended, and the maintenance cost is reduced (the service life is extended by 2-5 years).
4. The distribution of cement particles is optimized: when using the special grinding body of cement dry mill to produce ordinary cement, the grinding temperature is low, the body electrostatic effect is small, the grinding efficiency is high, the fineness of cement powder and the controllability of specific surface area are further improved, the particle shape of cement powder is better, the number of effective particles of 3-32 micro meters is obviously increased, so the early and later strength of ordinary cement is improved; As the particle size tends to be reasonable, the water demand of ordinary cement and the adaptability of additives are further improved, the comprehensive quality of cement is improved, the reputation of products and the competitiveness of the market are improved.
5. Improvement of cement adaptability: when using the special grinding body of cement dry mill to produce ordinary cement, the temperature inside the mill is low, and the temperature of cement out of the mill is very low, which solves the cement stability problem caused by the short interval from the mill to the factory. Especially in the high temperature season and the use of cement in concrete enterprises, the effect is more obvious.
6. Environmental protection: in recent years, the harm of hexavalent chromium in cement has attracted more and more attention from all walks of life and environmental protection departments. The state proposed on May 26, 2013 to limit the soluble hexavalent chromium in cement. In the traditional grinding process of ordinary cement, the application of high web steel ball and lining plate is the main source of hexavalent chromium, and there are few solutions. After adopting the special ceramic grinding body and ceramic lining plate process for cement dry mill, the direct contact between high chromium metal and cement is eliminated, the soluble hexavalent chromium content in cement is greatly reduced, and the environmental protection significance of carpet can be obtained from the government and environmental protection department Support and promotion.
7. Wear resistance and noise reduction: wear-resistant ball is more wear-resistant than steel ball, ball consumption is 50% of steel ball, and the noise of wear-resistant ball is lower in the use process.
