Effects of grinding processes on enzymatic degradation
2012-1-1 The main effect of steam explosion process of wheat straw was the solubilisation and extraction of 92% of original hemicelluloses (SE-WS content × 0.46/wheat straw content, 0.46 is the mass recovery of SE-WS fraction after steam explosion). Moreover, cellulose was also partially removed (24%).

Effects of grinding processes on anaerobic digestion of
2015-11-15 The effect of ultra-fine milling of wheat straw was investigated on biogas production. Particles classes from 759 to 48 μm were obtained. Anaerobic biodegradability tests revealed that grinding has no effect on the total methane potential values but influences the methane production kinetics, particularly for particle sizes lower than 200 μm

The effect of grinding process on mechanical properties
2010-1-10 Grinding process of cenospheres increases the specific gravity and fineness, and consequently results in higher pozzolanic reactivity of the fly ash,. According to Cornelissen et al. [14],the use of ground fly ash as a pozzolanic material in concrete production results in higher strengths with no negative effect on workability.

Effect of the grinding process on the wear of a cemented
2021-1-1 Effect of the grinding process on the wear of a cemented tungsten carbide cutting insert during turning. Within this context, two grinding wheels with abrasive grain sizes of 15 µm and 46 µm were used to finish WC-5%Co cutting inserts, applied afterwards in turning of AISI 4140 steel. It was demonstrated that the use of a smaller abrasive

Effects of grinding processes on enzymatic degradation of
The wheat straw degradability was enhanced by the decrease of particle size until a limit: ∼100 μm, up to 36% total carbohydrate and 40% glucose hydrolysis yields. Ball milling samples overcame this limit up to 46% total carbohydrate and 72% glucose yields as a consequence of cellulose crystallinity reduction (from 22% to 13%).

Effect of grinding aids and process parameters on dry fine
2021-7-1 Ball-milling cement raw materials requires only a few percent (<5%) of grinding aids [].To achieve finely ground PTFE, a mass ratio of the grinding aid (NH 4 Cl or CO(NH 2) 2)/PTFE of 4 was required.Therefore, the ammonium salts (NH 4 Cl and CO(NH 2) 2) not only played the role of a grinding aid, but also acted as the grinding medium (submicron-sized grinding balls)

Effect of miscanthus addition and different grinding
2012-9-1 This effect is slightly visible for the bulk densities but for both grinding processes . The addition of binder affects mainly the gross density and only in the impact grinding process. One remarkable aspect is that an increase of the gross density can be seen only for the pellets with a miscanthus share of 0 and 0.1 kg kg −1.

Grinding Processes SpringerLink
Grinding is the common collective name for machining processes that utilize hard, abrasive particles as the cutting medium. The grinding process of shaping materials is probably the oldest in existence, dating from the time prehistoric humans found that they could sharpen their tools by rubbing them against gritty rocks.

2021-11-2 Enhancing the extraction rate is one of the key objectives in optimization of extraction of substances from biogenic raw materials. Ultra-fine grinding of plant raw materials (to achieve particle size less than 300 µm) is a very appealing method for increasing the extraction rate using relatively simple equipment. However, this approach often fails to yield the desired
