The Lafarge BB10 test is a special ball mill system with certain standard procedures. In the case of clinker, the basic output of the test is a curve, relating fineness reached blaine in the case of clinker, m in the case of raw materials to the number of rotations of the BB10 mill system. The latter is proportional to energy input.
This page is a short introduction. The Understanding Cement bookebook contains a more detailed description of the hydration process and the hydration products. Clinker is anhydrous without water having come from a hot kiln. Cement powder is also anhydrous if we ignore the small amount of water in any gypsum added at the clinker grinding stage.

Sep 27, 2004 This paper was aimed at studying the variation of breakage rate parameters in the Bond mill. Batch kinetic experiments with monosize feeds and standard locked-cycle Bond grindability tests with natural size feeds were carried out on cement clinker and trass samples.
This paper investigates grinding of mineral mixtures with different grindabilities in the Bond ball mill. Understanding the ore mixture grinding is of great importance in mineral processing. The energy required for crushing and grinding is presented by the Bond work index and is determined by means of Bond grindability test. This paper presents the experimental results of the Bond work index ...

The test simulates a closed grinding circuit in a standard ball or rod mill. At CEMTEC, these tests are conducted with batch mill ELLA . After determining the Bond work index, the specific comminution capacity is calculated using the formula listed at the bottom of the page, factoring in various correction factors obtained from experience.
Oct 20, 2017 clinker grinding to cement composition of raw materials. Raw Material Preparation. This meant that, for the first time, there was virtually no limit on the fineness that could be achieved. From the early 1900s, both for cement grinding and for grinding hard raw materials, whether by wet or dry process, the standard arrangement was a ball mill ...

Ordinary Portland Cement Clinker is the core component in producing cement which is formed by sintering limestone. In the manufacturing of Portland cement, clinker formed by sintering or fusing together without melting to the point of liquefaction, alumina-silicate materials such as clay and limestone during the cement kiln stage and happens as 3 millimeters 0.12 in to 25 millimeters 0.98 ...
May 24, 2013 Bond and Hardgrove grindability methods were employed to determine grindability properties clinker and colemanite by varying proportions. Bond work index BWI values of clinker and colemanite are 18.89 kWht and 12.33 kWht, respectively.
Bond work index value of these components mixtures is greater than the Bond work in-dex of harder components, clinker. Oner 2000 have conducted a research of clinker and blast furnace slag mixture Bond Work Index in different mass propor-tions. He found out that these values are always lower than the Bond Index obtained

Mar 08, 2012 The grinding of clinker to make cement requires a great deal of energy. The microstructure of the clinker nodules has a decisive role as to how easy it is to grind. Data from microscopy and laboratory grinding of clinker shows the influence of the amount and size of the individual crystals on predicted grindability.
Bond Grains WA Size 80 Grade J Structure 7 Bond Example V35 1. Abrasive grains Grain act as cutter, and mainly they remove the surface of workpieces. 2.
