In 2016, the 17th International Cement Technology and Equipment Exhibition set off another upsurge. In order to respond to the national call for energy conservation and emission reduction, reduce enterprise production costs, and improve enterprise economic and social benefits, wear-resistant ceramic balls have been widely used in the transformation and energy saving of the cement industry. Favor.

　　Several advantages of using wear-resistant ceramic balls in cement plants:

　　One is the small investment and low operating cost. Take the commonly used ф3.2×13m cement ball mill as an example: the output of the mill is about 55t/h, the average power consumption of cement is about 36kW·h, and the new type of special non-metal grinding body is adopted, and the average power consumption of the mill is reduced to 30kW · Below h. The electricity cost is calculated at 0.8 yuan/kW·h, which can save 4.8 yuan per ton of cement, and the annual cost is about 1.92 million yuan based on the mill production capacity of 400,000 tons of cement. At the same time, grinding aids can be saved and the cost of cement can be further reduced;

　　The second is low material loss and long service life. The abrasion of the metal grinding body is 35-45g/ton cement, while the abrasion of the new non-metal grinding body is 15g/ton cement, which has a longer service life and less maintenance work;

　　The third is the safe operation of the mill. Due to the reduction of the mill current and the temperature of the bearing bush, the possibility of the mill tripping is greatly reduced, which is beneficial to the safe operation of the mill;

　　Fourth, the cement performance is good. Due to the use of a new type of special non-metal grinding body, the temperature in the mill and the water demand of cement are reduced, the amount of grinding aids is reduced, and the adaptability of cement and concrete admixtures is further improved, which is welcomed by concrete enterprises.

　　The new non-metallic grinding body is a revolutionary innovation to the grinding materials and grinding technology of cement ball mills. It has changed the long-term status quo of cement ball mills relying on metal grinding materials. It can effectively reduce the power consumption of the cement grinding system and save the cost of cement production. Reduce the chromium content in cement.

　　Traditional non-metal grinding bodies are used for cement and slag grinding, and generally have disadvantages such as low grinding efficiency, large wear, fragility, and low mill output. Therefore, metal grinding media are still commonly used in ball mills for grinding cement and slag. . However, the new non-metallic grinding body is a revolutionary innovation to the grinding materials and grinding technology of cement ball mills. It has changed the long-term status quo of cement ball mills relying on metal grinding materials. It can effectively reduce the power consumption of the cement grinding system and save cement production costs. , While reducing the chromium content in cement. As we all know, the cement ball mill is the key equipment for preparing cement by pulverizing cement clinker, gypsum, and mixed materials. When the barrel of the ball mill rotates, the grinding body is brought to a certain height due to the action of inertia, centrifugal force, and friction, and is thrown off by gravity, crushing the material in the barrel to realize cement grinding. Grinding bodies are generally steel balls or steel forgings, and are loaded into each bin according to different diameters and a certain proportion.

　　The new non-metallic grinding body is based on the characteristics of the cement ball mill. Through the use of advanced algorithms on the movement trajectory and energy change of the grinding body in the mill, the critical threshold of the grinding body's force is calculated, and the force boundary conditions of the grinding body are calculated. . One of the cores of this technology is a new type of special non-metal grinding body material. By changing the material ratio of the non-metal grinding body, element adjustment, molding preparation technology and other modification technologies, a new type of special non-metal grinding body suitable for cement mill conditions Grinding body material. Compared with traditional metal abrasive materials, its advantage is that the specific gravity is small, about 1/2 of that of steel balls; the wear is low, about 1/3 of that of steel balls.

　　At the same time, according to the internal structure of the mill and the law of motion of "ball, material, wind", through adaptive design adjustments to the internal structure of the mill, and with the roller press and classifier, precise transformation plans and control measures are formulated , To realize the purpose of saving production cost, reducing cement power consumption and improving cement performance of cement grinding system.
