Cellulose - NETZSCH Grinding & Dispersing

Cellulose is a white substance insoluble in water, which is found in cotton in an almost pure form (up to 95%), but is primarily extracted from wood because that is most easily cultivated and processed by all cellulose suppliers. The cellulose contained in the wood is separated out by means of so-called acid or alkaline pulping processes ...

A comparative study on the effects of dry and wet

2019-9-1 · Dry grinding has significantly lower media and liner wear than wet grinding; thus, the Fe concentration in the pulp of downstream process for the same mineral is relatively lower after dry grinding.
