smooth grinding

It is permissible for grinding marks to be present. Not as smooth as 2 D or 2 B.

(不过)可以允许有磨痕存在, 而不是达到2D或者2B的光滑度!

The grinding efficiency of smooth roll and centrifugal impactor was researched through the milling test of eight_roller mill at same flow rate and different roll gap for C1A and C2A during processing.

在实际生产中对八辊磨粉机的光辊心磨系统C1A/C2A进行不同轧距下的研磨试验，探索在流量相对稳定的情况下，光辊心磨与撞击松粉机的粉碎效果。

The ultramicro green tea powder grinded using superfine grinding technique requests tender raw materials with high level of chlorophylls, by which ultramicro green tea powder with characteristics of small size particles, smooth taste and bright green colour can be prepared.

通过超微粉碎技术获得的绿茶粉，要求原料持嫩性好，同时叶绿素含量高，使茶粉粒度小、口感滑润，且色泽鲜绿。

We used grinding machines only to smooth and finish a workpiece.

我们只是用磨床将工件抛光和精加工.
