clinker sieve analysis for grinding mill:

PAPER OPEN ACCESS The grinding clinker pressure process

clinker with a height of embankment from 10×10-3 to 40×10-3 m, with a constant pressing pressure of 50 MPa have been conducted. Graphic analysis of Fig. 2 made it possible to establish that with an increase in the initial clinker layer height, the grinding process efficiency decreases, but remains fairly high. This indicates that the

reduction in grain size of the clinker sample. Before grinding, evaluation of the grain size distribution showed no particles below 45 µm (Figure 3, A). After 30 s of grinding, the portion of particle below 45 µm significantly increased to 87.0 ± 0.9 % (mean ± standard deviation). After 30 and 60 s of grinding, the sieve analysis showed ...

Mar 01, 2006  The initial charge of cement clinker was dried at 105 °C and sieved between 2.8 and 0.09 mm, using a √2 sieve series to obtain different cement clinker fractions. Cement clinker loads used in the experiments were either crude feed material (− 2.8 mm) or mono-sized fractions (2–1.4 or 1–0.71 mm), or mixtures of the crude material with ...
