Ball mill.Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other.
In brief, the extractive-free, vacuum dried 40c overnight switchgrass samples were ball-milled in a porcelain jar with ceramic balls using a rotatory ball mill running at 96 rpm for 168 h under n 2.The milled fine cell wall powder was then subjected to enzyme treatment in acetic acidammonium acetate buffer ph 4.8, 50c under continuous.
Results on eight continuous ball mill tests are included.Experimentation was performed in a 0.99 m diameter air-swept mill at the kennedy van saun facilities in danville.In the first four runs, the effect of production rate on size distribution of product was tested for the powder filling level around 0.83.The ground switchgrass was.

The maize corngrass1 cg1 gene encodes a microrna that promotes juvenile cell wall identities and morphology.To test the hypothesis that juvenile biomass has superior qualities as a potential biofuel feedstock, the cg1 gene was transferred into several other plants, including the bioenergy crop panicum virgatum switchgrass.
Switchgrass biomass has been reported to produce more than five times more energy than the energy expended during production, harvesting, and processing, and the plant has significant environmental benefits schmer et al., 2008.The key step in the conversion of lignocellulosic biomass into renewable fuels is the release of fermentable sugars.
In brief, 20 mesh switchgrass biomass was soxhlet-extracted with benzene-ethanol 21, vv for 24 h to remove extractives.The extracted wall residue was then milled in a porcelain jar 1 l with ceramic balls using a rotatory ball mill running at 96 rpm under nitrogen for 120 h.
