Performance characteristics of ball mill rubber lining

(1) The rubber lining reduces the grinding energy consumption of the ball mill and improves energy efficiency. The mineral processing plant adheres to the concept of "reducing costs, increasing efficiency, and optimizing the five rates" to minimize the unit energy consumption of grinding without affecting normal production, so as to improve the energy efficiency of the grinding process. The rubber lining is thin in thickness, light in weight, and can be deformed when impacted. Under the same conditions, the operating load is reduced, and the power consumption per grinding unit is significantly reduced, which saves grinding costs and greatly improves economic benefits.

(2) The rubber lining has good wear resistance and extended service life. Among various types of wet ball mills in China, the traditional high manganese steel lining plates are not suitable for ball mill linings because the manganese steel lining plates have the disadvantages of rapid corrosion and wear, easy breakage, short life, and high steel and energy consumption. Among them, the Corrosion wear is the most prominent. The rubber lining is made of a highly elastic material. It is used to make the wet ball mill lining. It is not affected by the corrosion and wear of the slurry. Its corrosion resistance is much stronger than that of the high manganese steel lining. The elasticity of the rubber lining is It is also able to absorb the impact of larger grinding media, thus protecting the mill structure.

(3) Rubber lining reduces production noise and improves the mining environment. The main source of noise in the mine workshop of the mineral processing plant is the high noise generated during the operation of the ball mill. The noise pollution of the ball machine is aggravated. The noise is harmful to the health of workers. The noise of the manganese steel lining mill is very large. The noise of the ball mill in the mineral processing plant is generally 100~ 105 decibels, which greatly exceeds environmental protection regulations and seriously corrodes workers' hearing health. When grinding mill workers work under noisy conditions, the continuous influence of strong noise can cause morphological changes in the auditory organs, that is, induce qualitative lesions, cause hearing loss, and even occupational deafness. Therefore, controlling the operating noise of the ball machine is an important progress in the civilized production of modern dressing plants. Since the rubber lining is a lining made of highly elastic material, when the mining plant medium affects the lining, it can maximize the noise generated when it collides with the rubber lining, thereby reducing noise pollution and improving the working environment of the grinding workshop. , workers’ health.

(4) The rubber lining is light in weight and easy and safe to install. Rubber liners are lighter than high manganese steel liners. The weight of a high-manganese steel lining plate is generally about 400 kg, which brings inconvenience to transportation and installation. During the overhaul, loading and unloading of the lining plate, workers are often injured because the lining plate is too heavy, and the labor intensity of the workers is relatively high. big. A single rubber lining is only about 60 kg, and a heavier single lifting bar does not exceed 200 kg, which is less than half the weight of high manganese steel linings, which can effectively reduce the labor intensity of repairing linings and avoid the danger of loading and unloading linings. accidents, ensuring the safety of workers, saving installation time and maintenance costs, and relatively improving the operation rate of the ball mill.

Application advantages of rubber lining in ball mill

(1) The price/performance ratio is higher;
(2) The power consumption per ton of ore of the ball mill is reduced;
(3) The unit consumption of steel balls is reduced;
(4) The working noise of the ball mill is greatly reduced and the working environment of workers is improved;
(5) Reduce the lining installation time and reduce the work intensity of workers.
