H2 generation during dry grinding of kaolinite

Journal of Colloid and Interface Science, 2004
H2 generation during mechanochemical treatment of kaolinite by dry grinding was examined by X-ray diffraction analysis, Fourier transform infrared spectroscopy, and BET surface area measurement. The H2 concentration in the mill pot, measured by gas chromatography, increased with grinding time up to a maximum concentration of 156 ppm (0.35 micromol ...

Cellulose conversion in dry grind ethanol plants

Bioresource Technology, 2008
The expansion of the dry grind ethanol industry provides a unique opportunity to introduce cellulose conversion technology to existing grain to ethanol plants, while enhancing ethanol yields by up to 14%, and decreasing the volume while increasing protein content of distiller's grains.

Dry plunge cylindrical grinding utilising structured grinding wheel

International Journal of Mechatronics and Manufacturing Systems, 2012
In order to perform the grinding process in dry condition, the chip formation needs to be optimised so that the friction between the grinding wheel and the workpiece is minimised. The Institute of Grinding and Precision Technology (KSF) conducts a profound research to find out optimal conditions in order to apply the dry machining to plunge cylindrical

Dry grinding process with workpiece precooling

CIRP Annals, 2015
Abstract This paper proposes a workpiece cooling prior to grinding in order to allow a dry processing. Tests and simulation showed good potential. The obtained part quality is good, and there is no thermal damage since there is a higher heat flux from the grinding zone to the workpiece due to the much lower temperature of the last. The process design

Wheel wear in dry surface grinding

International Journal of Machine Tool Design and Research, 1976
Abstract Wear phenomena accompanying dry surface grinding of mild steel under plunge cut conditions were investigated from the force pattern, grinding ratio and wear particle size removed from the wheel. Wheel wear estimates were obtained from the amount of abrasive grains collected during grinding.

DRY GRINDING OF SOIL THIN SECTIONS

Canadian Journal of Soil Science, 1971
A method is proposed for making soil thin sections using dry grinding after mounting with an epoxide. Excellent thin sections were completed using all soil materials tested in this laboratory, including dense, clayey and impermeable samples which are difficult to impregnate and polish.

Effect of Dry Grinding on Kaolin Minerals

Clays and clay minerals (National Conference on Clays and Clay Minerals), 1957
AbstractThe effect of dry grinding of kaolin minerals by a mechanical mortar was examined by x-ray, thermal, and electron microscopic methods. Base exchange capacity and apparent density were also measured. In the early stage of grinding, kaolin crystals cleave and fracture and then split into fine crystals which are considered unit crystallites.

Sustainability of Gear Manufacturing With Dry Grinding

Volume 2: Manufacturing Equipment and Automation; Manufacturing Processes; Manufacturing Systems; Nano/Micro/Meso Manufacturing; Quality & Reliability
Abstract High quality gears for automotive applications require a high level of geometrical accuracy and surface finish of the gear flank to improve the operational performance while reducing the noise during their lifecycle. Generally, the high-quality gears are produced using a final grinding process for surface finishing, this reduces

The effect of dry grinding on the structure of talc

Applied Clay Science, 1994
Abstract The effects of dry grinding on the textural and structural properties of a well crystallized talc are studied. Intense mechano-chemical effects occur even at short grinding times due to the low hardness of talc. The physico-chemical and structural alterations are evaluated by BET surface area, particle size, porosity, CEC, solubility, DTA ...
