Embodiment 1
[0017] Such as figure 1 As shown, the flotation feed material is fed into the surface modification pulping machine through the feed pump to make a certain concentration, uniform and stable pulp, and at the same time the addition of chemicals is realized in the pulping machine; the pulping machine uses a certain The speed and time are used to strengthen the pulp adjustment, and the prepared pulp is automatically fed into the rougher flotation machine, and the fed pulp is floated by the rougher flotation machine to obtain flotation coarse and clean coal and rougher tailings. The tailing coal can be used as the final tailing coal. The coarsely selected clean coal then enters the selection flotation machine for selection operation to obtain the final clean coal and selected tailing coal. The selected tailing coal returns to the surface modification and pulping machine through the transfer pump Sorting again in order to improve the recovery rate of flotation clean coal.

Embodiment 2
[0022] Such as Figure 5 As shown, the floating coal slime is fed into the surface modification pulping machine through the feed pump to make a certain concentration, uniform and stable slurry, and at the same time, the addition of chemicals is realized in the pulping machine. The speed and time are used to strengthen the pulp adjustment, and the prepared pulp is automatically fed into the rougher flotation machine, and the fed pulp is floated by the rougher flotation machine to obtain flotation coarse and clean coal and rougher tailings. The tailing coal can be used as the final tailing coal. The coarsely selected clean coal then flows into the primary selection flotation machine for a selection operation to obtain a primary selection of clean coal and a primary selection of tailing coal. The primary selection of clean coal then flows into the secondary The selection flotation machine carries out the second selection, and the second selection clean coal is obtained as the fin...
