MILL EXPERIENCE OF CALCIUM CARBONATE SCALE

2 Figure 1. Calcium carbonate scale formation in green liquor pipeline at two kraft mills. CaCO3 has been identified as the main component of the hard scale, particularly at locations downstream of the dissolving tank [1-4]. A systematic study was conducted at the University of Toronto to examine how CaCO3 forms and what makes the scale hard [5].

Ground Calcium Carbonate / Limestone Mineral

Pure calcium carbonate is a relatively soft mineral/compound, with a Mohs hardness of 2.5 3.0. However, mined limestone may have a minor portion of abrasive impurities such as quartz / sand. One of the standard methods of milling Limestone/Calcium Carbonate is with the Mikro ACM Air Classifying Mill. The ACM has a rotating rotor disc with

How to Maintain Calcium Carbonate Raymond Mill

However, for calcium carbonate Raymond mill, due to the harsh environment in the grinding cavity (high dust concentration), the grinding roller assembly is also easy to run into dust in the sealed state, which intensifies wear and breaks faster, sometimes even worse. It will seriously affect the normal operation
