suit all mill OEM's. Key benefits. Cement grinding. The feed for a cement grinding unit will normally be dry and. needs to be ground to a high degree of fineness. To achieve this efficiently, most mills will be split into two chambers. The first is set up for coarse grinding with a target to grind the feed materials down to around 1 mm.

Another significant consideration is that cobalt chrome is very heatresistant with low thermal conductivity. During cutting of standard steels, heat generally is evacuated through the chip. However, with cobalt chrome, heat does not generate into the chips. Because of this, the heat concentrates at the cutting edge of the tool," said Doiron.

The chromium is vital because it reacts with oxygen and creates a kind of insulating layer that protects the steel from corrosion. Keep this in mind: the higher the level of chromium, the better able to resist rust the grinder is. However, since the mill grind by time, the layer which protect against from rust will be worn out as well.
