axial sampling in a cement mill

proper way to take axial samples in a Raw Mill Page 1 of 1

Please see the attached pictures regarding correct way of axial sampling in a crash stop: A few explanations: Need to dig 20 cm under the top material to take samples. Do this at three points on the width of the mill ( two samples from 0.5 m from sides of the mill and one from middle) and mix them before sieve analysis

How to Read a Cement Mill Certificate: Part 2 NPCA

2013-9-18  The cement mill certificate includes three performance tests that merit close attention: false set, Vicat setting time and strength. False set. False set is the tendency for cement mixtures to stiffen early, typically due to the sulfate in the cement reacting with the water to form gypsum crystals over the first few minutes of mixing.
