The grinding balls for diamond cement are equipped with 43 large-tonnage ball mills, 9 pressure/centrifugal spray granulation towers, 48 two-way compression molding machines, 40 isostatic pressure molding machines, and nearly 1,000 other international advanced ceramic production equipment. Taiwan sets, forming 9 independently operable ceramic product production lines, with an annual production capacity of 150,000 tons. The production line adopts high-standard design, standardized installation and construction, high technological process and technical equipment starting point, and has obvious advancement.
The main raw material is the high-purity ultra-fine a alumina powder produced by the grinding ball for diamond cement, which is prepared by powder (slurry, mud)-dry pressing, isostatic pressing (dry, wet) and other forming methods The semi-finished products of alumina ceramics-tunnel kiln firing and other dozens of unique technological processes of King Kong form the excellent performance of the product. Diamond alumina products have excellent performance such as wear resistance, impact resistance, corrosion resistance, high temperature resistance, energy saving, environmental protection, consumption reduction, and extension of the service life of the equipment. The performance indicators have reached the domestic leading and international advanced levels. After testing by the National Building Materials Industrial Ceramics Supervision, Inspection and Testing Center, all performance indicators of the product are better than the industry standard requirements, with a Mohs hardness of nine, a density of 3.62g/cm3, and an equivalent wear <0.01‰; the wear resistance is significantly higher than the current Commercially available alumina ceramics are one to two orders of magnitude. King Kong's "microcrystalline wear-resistant alumina liner" passed the appraisal of the achievements of the Shandong Provincial Science and Technology Department. The result appraisal opinion believes that the overall quality of the "microcrystalline wear-resistant alumina liner" has reached the international advanced level. based on the technology of the product, 2 national invention patents have been declared, and 1 utility model patent and 3 design patents have been authorized. In 2012, Jingangyixing ceramic products were awarded Shandong Famous Brand.
King Kong alumina special new material products account for 40% of the global market share, and its production and sales have ranked first in the alumina wear-resistant industry for many years, becoming the world's first.
Introduction to the advantages of cement grinding balls:
1. Low energy consumption: the density of the special grinding body for cement dry mill is about 3.65g/cm3, and the density of the high-concentration steel ball is about 7.8g/cm3; the total weight of the special grinding body for dry mills of the same volume is lower than that of the traditional grinding body. Doubled, the current of the main engine is reduced, and the temperature rise is also reduced; at the same time, because of its lighter weight, it can also increase the filling rate of the mill appropriately, improve the grinding efficiency, and increase the production stage, thereby further reducing the unit Power consumption (power saving ≥20%).
2. Low temperature: The special ceramic grinding body for cement dry mill is an inorganic material. During the grinding process, its heat is very small, no static electricity is generated, and the temperature is low, which accelerates the fluidity of the cement in the mill (the cement temperature is reduced by 20%. the above).
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. The overall damage of the grinding head and the corresponding supporting facilities of 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 for cement dry mills to produce ordinary cement, the temperature in the mill is low, the electrostatic effect of the body is small, the grinding efficiency is high, the fineness of the cement powder, and the controllability of the specific surface area are further improved. The particle size of cement powder is better, and the number of effective particles of 3-32 microns has increased significantly, so that the early and late strength of ordinary cement will be improved; as the particle size tends to be reasonable, the water demand and admixture adaptability of ordinary cement are further improved , To enhance the comprehensive quality of cement, improve the reputation of the product and market competitiveness.
5. Improved cement adaptability: When the special grinding body of cement dry mill is used to produce ordinary cement, the temperature in the mill is low, and the temperature of the cement out of the mill is very low, which better solves the problem of the short interval caused by the cement from grinding to leaving the factory. Cement stability issues. Especially in the high temperature season and the use of cement in concrete enterprises, this effect is more obvious.
6. Environmental protection: The hazards of hexavalent chromium in cement have attracted more and more attention from all walks of life and environmental protection departments in recent years. On May 26, 2013, the state drafted a restriction on the soluble hexavalent chromium in cement. In the traditional grinding process of ordinary cement, the application of high-rolled steel balls and liners is the main source of hexavalent chromium. There are not many solutions. The special ceramic grinding body and ceramic liner technology for cement dry mills are used to eliminate The direct contact between high chromium metal and cement reduces the content of soluble hexavalent chromium in the cement. The environmental protection significance of the carpet can be supported and promoted by the government and environmental protection departments.
7. Wear-resistant and noise-reducing: Wear-resistant balls are more wear-resistant than steel balls, and the ball consumption is 50% of steel balls, and the noise of the wear-resistant balls is lower during use.
