The change of the Blaine specific surface area versus the specific energy for the clinker size fraction (1–0.71 mm) is shown in Fig. 1.For these runs, mono-sized balls having a diameter of 10 or 20 mm were used keeping constant the other parameters (J = 0.45, U = 0.8 and N = 65 rpm).In a preliminary study, it was shown that the net mill …

Cement milling Question 28. We have a two-chamber ball mill 2015· Lastly their consistency will vary •Mixture proportions of the raw materials must be continually adjusted •Therefore the SEAL system avoids spillage during transport and prevents any kindof cement (0.04% - 0.12% of total weight = cement clinker + additions).

Coarse cement particles settle down in concrete which causes bleeding. Approximately 95% of cement particles are smaller than 45 micrometers, with the average particle around 15 micrometers. In the …

Three cements produced from the same clinker but of widely different finenesses were obtained from a U.S. cement plant. Blaine finenesses and oxide compositions, as …

The proposed model correlates the specific grinding energy, the clinker work index and the specific surface (Blaine) of a cement produced through fine-grinding in ball mills.

The effect of the Blaine fineness (Bf) of the slag is one of the most important parameters investigated in the present study. ... In the today's world, cement is considered to be the most used material in the world after water. Cement production is also a process consuming high energy, such that the energy used to produce cement per ton of ...

This study investigated the effect of feed amount and composition on Blaine fineness and cement residue when grinding clinker and additive materials in a cement mill. The Blaine fineness, which measures specific surface area as an indicator of cement fineness, was found to decrease with increasing feed amount and changing composition. Meanwhile, …

Common methods of cement fineness measurements, such as sieving or Blaine-device that are used to specify the cement's specific surface, just deliver a single amount after laborious analyses, whereas laser diffraction analysis measures a wide range of particle size distribution with considerable accuracy. Also, the grade of grinding is ...
