Embodiment

[0037] Refer below figure 1 , 3 , 6(a), 6(b), 6(c), 6(d), 6(e), 7(a), 7(b) describe the application of the ball mill of the present invention, the mill barrel is provided with grinding media As for the lining plate 2, the grinding medium adopts the same specification grinding medium. Grinding media can choose grinding ball 1 and grinding section.

[0038] When the grinding medium is a grinding ball, the grinding ball adopts a grinding ball 1 with a uniform ball diameter, and the selection range of the grinding ball diameter depends on the requirements of the input particle size and the output fineness, and can be from Ф10mm to Ф40mm. The surface of the liner 2 is provided with several grooves. A number of grooves are arranged on the liner plate in parallel with the material running direction, and the distance between the grooves is the same as that of the grinding balls. The size of the groove is adapted to the diameter of the ball, that is, the ball and the groove can fi...

experiment example

[0043] The ball mill designed according to the latest ball mill grinding theory proposed by the present invention and the principle consistent with the liner can bring about 10%-16% increase in output, or about 15% power saving at the same output. For example: the ball mill with a diameter of 3.8m x 13m in the production of cement clinker industry had an output of 135 tons / hour before applying this design, but after applying this design, its output increased to 150~155 tons / hour; The use of the warehouse plate eliminates the accessories with the highest maintenance and replacement rate of the ball mill. The comparison data is as follows in Table 1:

[0044] The specific surface area is a professional term for cement, that is, the size of the particle surface area of ​​a certain quality, the larger the specific surface area, the better the particle shape. From the experimental data in the table above, it can be seen that, without fully optimizing the shape of the liner, the pr...

Abstract

The invention discloses a ball mill and particularly relates to a ball mill, wherein the latest grinding theory of the ball mill is put forward. The ball mill comprises a ball mill cylinder, wherein a grinding medium and a liner plate are arranged in the ball mill cylinder; and the grinding medium is a grinding medium in a same specification. The invention further provides a use method of the ball mill. According to the ball mill disclosed by the invention, by using a grinding ball with a uniform ball diameter or a grinding section with a uniform size in the ball mill, the largest grinding area in the whole space of the ball mill is obtained in all the working time, so that reduction of the effective grinding area caused by grading is reduced; and a partition plate is cancelled, and the ball mill is completely used for grinding work, so that the grinding efficiency and output are increased, and maintenance work caused by the partition plate is omitted.

Description

technical field [0001] The invention relates to a ball mill and its use method, in particular to a ball mill and its use method according to the anti-gradation theory of the grinding medium of the ball mill. Background technique [0002] Ball mills are the main grinding equipment used in mining, cement, electric power, chemical and other industries. According to statistics, the annual consumption of metal linings in the country is about 600,000 tons. The energy consumption of the ball mill is high, and the energy utilization rate is very low, only about 15%. Countries around the world require energy saving and emission reduction, and improvement of ball mill efficiency. How to improve grinding efficiency and reduce power consumption and wear-resistant material loss is an important issue in grinding production. The work of the ball mill mainly depends on two parts: the grinding between the grinding balls and the grinding between the grinding balls and the liner. Traditiona...
