Mohs’ hardness is used for measure the minerals’ hardness, it was divided into 10 grades, take talc as an example, it’s hardness is Mohs’ 1, and the hardest material on the world is diamond, it’s Mohs’ 10; and that interesting, our skin hardness is Mohs’ 2, it’s more harder than talc is. Clirik HGM micro powder grinding mill can be used in Mohs’ hardness less than 6 minerals, there are about 150 kinds of minerals on the earth, such as: talc, dolomite, limestone, calcium carbonate, carbon black, graphite, calcite and so on. However, there are also some other minerals Mohs’ more than 6, but can be sued in our micro powder grinding mill to process powder, but it will cause much worn, so we don’t recommend you to process quartzpowder by our HGM micro powder grinding mill.

Quartz: the quartz Mohs’ hardness is 7, it was mainly used in glass making after be grind into quartz powder, there are also many customers choose our HGM micro powder grinding mill to process quartz powder; although, our grinding mill can process quartz powder, the quartz powder fineness made by micro powder grinding mill cannot reach more than 1500 mesh, if you want to process more than 1500 mesh quartz powder by micro powder grinding mill, it will cause huge consume of grinding rollers and grinding rings, it’s not economical.

HGM micro powder grinding mill is good for Mohs’ less than 6 materials powder grinding; however, if you want to process minerals which Mohs’ are more than 6, or even more higher, what kind of machines you can use? Don’t worry, Shanghai Clirik is a processional manufacturer of powder grinding mills, that’s true, use HGM micro powder grinding mill cannot be helpful when you want to process hard minerals, but you can choose another ultra fine powder grinding machine, it’s our new technology CLUV ultra fine vertical roller mill.
