With its new KSD-A vertical edge processing machine, LiSEC pays special attention to the glass edge. Depending on the end product and the follow-up process in glass finishing, the glass must have a ground (KMG) or seamed (KGS) glass edge. The new KSD-A, with its patent-pending LiTEC slider processing tool goes a further step toward increased efficiency, especially for challenging glass …
Grinding is exclusively performed through nipping method where media can be ball or rod. Size of Size of the media is a relevant factor of ore characteristics and output qualit y.
The present work examined the fragmentation of an aluminosilicate nanoscroll in response to manual grinding. Specifically, we report the preparation of kaolinite nanoparticles based on complete breaking the tube walls of kaolinite nanoscrolls ().Kaolinite is a 1:1 type layered aluminosilicate having the formula Al 2 Si 2 O 5 (OH) 4, and comprising stacked neutral layers, each of which ...
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.

A method and apparatus for the dry grinding of solids, comprises initial coarse grinding of the solids in a controlled vortexing of a fluidized bed and directing the solid fine particles generally upwardly into a vortex grinding zone and grinding the upwardly directed solid particles in the vortex grinding zone by passing a portion of the particles through the vortex grinding zone.
Dry grinding is generally performed in a grinder, and results from an autogenous grinding method, in which the particles to be ground strike one another, or result from additional impact with one or more other materials, such as grinding beads. Such grinding may occur, for example, with a ball mill, vibration mill, or wheel mill.
