What do you use to grind carbide? The solid carbide knife is ground with diamond grinding wheels in a two-step process. The profile is rough ground with 80 or 100 grit diamond wheels, and the finish grind is performed with 150 or 200 grit material. Plunge cuts or aggressive grinding are not recommended. Is calcium carbide banned in India?

Carbide slag, also known as calcium carbide residue (CCR), is a by-product of the hydrolysis of calcium carbide. It is commonly generated from the industrial production of ethylene, polyvinyl chloride (PVC) and other products as a solid waste. Currently, it has no value for recovery and is commonly landfilled. At some Chinese plants, this slag is used as an alternative raw material …

Calcium carbide in the mixed carbides was selectively decomposed to hydrated lime and acetylene by reaction with H2O, and this reaction concurrently liberated the unreacted TiC. The resulting hydrated lime was separated from the TiC by dissolution in H2O and by physical methods, including elutriation and gravity separation.

The preliminary grinding of calcium carbide with or without an inert liquid in a ball mill is, however, extremely dangerous, particularly if air or traces of moisture are present. If ether is employed as the inert grinding medium, the process is still more dangerous, since sufficient heat is developed to boil the ether and build up pressure.
