Afterwards, locking nut 18 is screwed, at this point, the adjustment of milling gap 19 finishes, then lifting cylinder 301 drives upper cylinder 601 vertical
Decline, until upper cylinder 601 is contradicted with lower cylinder 602, and is arranged sealing ring 603 between upper cylinder 601 and lower cylinder 602, cylinder in raising
Leakproofness between 601 and lower cylinder 602, at this point, grinding operation can be continued；When needing grinding superfine material, diminution is ground
Gap 19 is ground, so that the bed of material controlled in milling gap 19 is relatively thin, and will not directly be contacted between grinding roller 10 and bull ring 9, thus
Reach the grinding of superfine-material, meanwhile, noise is small, also, causes grinding roller to wear when grinding roller 10 is used for a long time, so that adjusting originally
Milling gap 19 when becoming larger, at this point, still milling gap 19 can be readjusted by adjusting component 16, extend and use the longevity
Life.
