Vacuum Welding of Olivine | Science

Welding of olivine was demonstrated by grinding it in a ball mill in an atmosphere of about 2 x 10-7 torr. Most of the sample adhered strongly to the container and grinding balls although adhesion in air is only slight. Similar adhesion should be expected on the lunar surface and may account for the roughness needed to explain the optical properties of the moon and the detail of the una 9 ...

Fine Grinding of Coal by the Turbomilling Process

tuted for water, the milling of the coal was less effective and less energy efficient. Keeping the pulp dispersed was critical. Without an effective dispersant, the slurry became very viscous with increased milling time, reSUlting in higher energy requirements, low heat dis­ sipation, and poor grinding efficiency.

Arctic News: grinding

Milling of olivine (around 2 US$/ton for milling olivine to 100 micron) is a cost that can be avoided if nature provides a zero cost alternative. We have carried out experiments with angular coarse olivine grit in a simulated very modest surf (5). After a few days the grains were rounded and polished grains (Fig. 1).

grinding methods were nearly as effective at size reduction without concurrent increases in surface area. Some large particles remained after dry attrition grinding, as shown by sample AM-D's D80 value of 16.23 !-lm. This large D80 value is thought to be due to trapping of grains in "dead zones" of the mill that have no grinding action.
