### milling of oblique surface grinding mill electrician

The grinding rotors with deposited coatings were used for milling of the Portland cement, and rotors' weight loss was monitored after milling of 1, 3, 5, 10, and 15 kg of this material. The lowest weight loss in the mixed impact erosion conditions was exhibited by WC-CoCr coating, which was followed by Cr 3 C 2 -NiCr and NiCrBSi coatings.
