Embodiment 1
[0051] The device and method of the present invention are used to classify the overflow product (the raw ore of this embodiment) of the hydrocyclone of a large-scale state-owned enterprise in Jiangxi Province, a copper mine dressing plant. The useful minerals composed of raw ore are mainly chalcopyrite and pyrite, and the gangue minerals are mainly quartz, calcite magnetite and hematite. The raw ore density is 3.25g / cm3, and the raw ore particle size composition is shown in Table 1.
[0052] Table 1:
[0053] Grain fraction / mm Yield / % Cumulative yield under sieve / % -0.833+0.351 10.98 100.00 -0.351+0.147 13.04 89.02 -0.147+0.074 17.70 75.98 -0.074 58.28 58.28 total 100.00
[0054] Adopt device of the present invention, the operation step of classification is as follows:
[0055] According to step A: keep the water level 10cm lower than the upper end of the cylindrical screen, and keep the water in and out in balance;

Embodiment 2
[0066] The raw ore of present embodiment is with embodiment 1.
[0067] Adopt device of the present invention, the operation step of classification is as follows:
[0068] A step is with embodiment 1;
[0069] According to step B: adjust the rotational speed of the central shaft to 1000r / min;
[0070] According to step C: add ore pulp (mass concentration is 35%, and the addition speed is 4kg / min measured by dry ore) from the ore feeding pipe, and the continuous addition time of ore pulp is 30min;
[0071] D step and E step are with embodiment 1.
[0072] The calculation results of Example 2 are shown in Table 3.
[0073] table 3:
[0074] Grain fraction / mm Raw ore yield / % Fine particle product / % Coarse particle product / % E quality efficiency / % E volume efficiency / % -0.351 89.02 100.00 50.42 87.45 87.45 -0.147 75.98 85.69 38.65 42.22 89.50 -0.074 58.28 68.95 19.25 34.46 92.91
[0075] According to Table 3, the classificati...
