Jul 25, 2019· When cement is manufactured the final process is the grinding of the clinker to form powder. The fineness of this powder is an important property. The finer the grinding the higher the specific surface. The Blaine of cement refers to the fineness
Apr 07, 2013· can you please share your opinion about the what are the main levers to control the blaine and residue on 45 micron in cement product indivisually. take any case -1,our blaine is 3400 cm2/gm and residue on 45 micron is 13% and if we want to reduce the residue by 3% with out affecting the blaine, how it is posible? (or vise versa). thanks. regards

residue and blaine (specific surface area) values. Blaine value is a numerical value of the area covered by 1g material. It is impossible to interpret about performance of cement with these two values. For this reason, particle size distribution is performed with automatic devices via distribution curves. Particle Size Distribution in Cement
Nov 03, 2017· So to increase the setting time of cement, cement is ground in a different range of particle sizes. The following proportions are usually maintained in Cement: About 10% of the cement of fine particles is smaller than 2 µm, 10% of wt of cement is made of particles larger than 50 µm, and only a few wt% is particles larger than 90 µm.

Improved Cement Quality and Grinding Efficiency by Means of Closed Mill Circuit Modeling. (December 2007) Gleb Gennadievich Mejeoumov, B.S., Ivanovo State Power University, Russia; M.S., Ivanovo State Power University, Russia Chair of Advisory Committee: Dr. Dan Zollinger Grinding of clinker is the last and most energy-consuming stage of the cement
In the cement industry, there are three standard tests to measure the specific surface area: 6. Blaine in ASTM C 204 [1], Wagner in ASTM C115 [2], and sieve residue (45 µm sieve) in . 7. ASTM C430 [3]. The Wagner test is also referred as the turbidimeter fineness test because it measures the turbidity of a cement suspension in kerosene8 [4].
re cement blaine and residue on 45 micron control? Hello Raju, Since both are a measure of particle size, residue is normally linked to Blaine. But not always. It depends on the particle size distribution of the cement and this is driven by several things including mill design, ball charge (or grinding pressure in a roller mill), clinker
Insoluble residue is a non-cementing material which is present in Portland cement. This residue material affects the properties of cement, especially its compressive strength.

Portland Limestone Cement Part I Preparation of Cements 1340 İnan Sezer [5] investigated the physical and mechanical properties of cements prepared by replacing 0-6-21 and 35% of clinker with limestone by intergrinding method. The time required to obtain a Blaine value of 330 m2/kg has been determined. All other blended
“Blaine”) of a cement powder is a single parameter that is meant to characterize the specific surface area and, therefore, (45-mm) is used to measure the residue or retained amount of cement on a calibrated sieve as an esti-mate of what fraction of the particles are greater than a certain size. A sieve with a 45-mm opening
Insoluble residue is a non-cementing material which is present in Portland cement. This residue material affects the properties of cement, especially its compressive strength.
A comprehensive research project was undertaken to evaluate the effect of specific energy consumption (Ec) on variations of portland cement fineness measured by the Blaine test and sieve analysis.
response variable was weight percentage of product residue on 32-micrometer sieve (or fineness), while the input parameters were revolution percent, falofon percentage, and the elevator amperage (amps), which exhibits elevator charge to the separator. The process data collected from a local plant, Cimenta Cement Factory, in
The diagram here below shows the specific surface (Blaine) produced in order to achieve a certain percentage of residue on 30µm (From Duda Cement Data Book). For example, to get 20% residue on 30µm, a turbo separator needs to produce a cement at 3200-3900 Blaine and a : separator with cyclones 3000-3600 Blaine.
Jun 14, 2006· Therefore, a new batch of SRM 114 needed to be developed. This process included selection of the cement, packaging the cement in small vials, and determination of the values for the ASTM tests reported. In this case, the Blaine, Wagner and 45-mm sieve residue were the tests used. Later the particle size distribution (PSD) will be added.

Things to be Paid Attention in Application
Cement is seldom used on its own, but rather to bind sand and gravel together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is only behind water as the planet's most-consumed resource.
Changing the separator to a high efficiency type brings about better residue value (on 45 micron) for the same Blaine. Alternatively, the cement can be ground to a lower Blaine with the same residue, which determines the strength of cement. In most cases the layout permits replacing the separator to a
