The kinetics of dry grinding of several cement clinkers and two coals were investigated in a laboratory tumbling ball mill. The kinetic process is first-order at first, but the rates of breakage decrease as fines accumulate in the bed. It was demonstrated that the slowing of the breakage rates applies to all sizes in the mill, indicating that ...

The performances of dry-grinding fine cemenT (DFC) in grouting procedure were experimentally studied. The measurement of its fineness and simulated test for injectability showed that this DFC could be used to inject rock mass with micro-fissure. In order to improve the grouting quality, the water-cement ratio and discarding time of slurry should be controlled precisely. If the water-cement ...

1. Introduction. In various dry fine grinding applications, so-called grinding aids (GAs) are added to the feed material or directly into the mill either to a) increase the production capacity, b) reduce the specific energy demand, which is required to obtain a certain product quality, or c) achieve finer material or a better performance of the later product.

The s-Jet ® System (patent pending) is a new innovation in a line of consistent developments being made in the area of air jet milling. Final finenesses in the submicron range (example: d 50 0.2 µm) can now be achieved with fluidized bed jet mills. As opposed to conventional dry grinding processes with fluidized bed jet mills, the s-Jet ® System uses superheated steam as its milling gas.
