Problems solved by technology
[0005] In the prior art, if it is necessary to carry out the grinding test research on the diameter-to-length ratio of the ball mill, it is necessary to manufacture multiple ball mills with different diameter-to-length ratios. This will not only require high equipment investment, but also occupy a large test site, and the operation is very difficult and Complicated and difficult to implement

The invention discloses a multistage ball mill, including a cylinder and a driving device which drives the cylinder to rotate through the gear. The cylinder comprises a fixed cylinder (1), a plurality of cylinder units (3) and a feeding end cap (4). The discharging end of the fixed cylinder (1) is provided with a discharge end cap (2); the cylinder units (3) are arranged coaxially with the fixed cylinder (1) through a rotating rack, and can move axially to form working cylinder in different lengths with the fixed cylinder (1); and the feeding end cap (4) is arranged on the feeding end of the fixed cylinder (1) or the working cylinder. According to the ball mill, under a certain diameter of the cylinder, the length of the cylinder can be changed by adjusting the number of the cylinder units, so that the fineness ratio of the ball mill cylinder changes step by step in certain extent; therefore, combination of ball mill cylinders in different fineness ratios cab be achieved in one ball mill equipment, so as to meet the requirement of fineness ratio test research, fill the gaps in the research field, and create conditions for improving the scientific design and selection of ball mill.
Description
technical field [0001] The invention relates to the technical field of mineral processing equipment, in particular, it is used for grinding tests in a laboratory to determine the reasonable diameter-to-length ratio of a ball mill cylinder, thereby providing a basis for the design and type selection of the ball mill in the mineral processing process. Background technique [0002] The purpose of ore grinding is to dissociate all or most of the useful minerals in the ore to achieve the particle size range suitable for the subsequent sorting operation requirements, so as to create conditions for the sorting operation to effectively recover the useful minerals in the ore, and at the same time It is also necessary to avoid grinding the minerals too finely, which will cause the so-called "over-grinding" phenomenon, which will worsen the subsequent sorting operation. [0003] The particle size characteristics of grinding products directly affect the separation effect. Insufficient d...
