Re Mill to Blaine or Mill to residue. Normally a steeper distribution is expected to give a lower blaine than a wider distribution, the extent depends on the type of circuit u r operating with.surely basic operations with feed rate and recirculation will help as Mr.clark suggests.

Cement is a reactive powder thus, one of its most important characteristics is its psd, which, in turn, determines its total surface area. since the blaine measurement is related to a specific surface area area per mass of cement and is referred to as a fineness measure, total specific surface area is often referred to as a fineness measure.

Portland cement is the most common type of cement widely used around the world as a basic ingredient of concrete, mortar, stucco and non-specialty grout. it was developed from other types of hydraulic lime in england in the early 19 th century by joseph aspdin and usually originates from limestone.. raw materials for the manufacture of portland cement are found in nearly all countries.

Putting cement on it then determine the difference between two weights, this difference divided by mercury density in room temperature to obtain volume of cement bed. repeat this for twice at least and use the average value of volume in following equations, also the weight of cement used in cell must be with porosity equal to 0.5 177 0.0005.
The fineness of a portland cement is a key factor in determining its strength development characteristics. a simple oneparameter fineness characterization such as a blaine value or a sieve residue is often inadequate for a precise evaluation of the influence of fineness on the strength development of cement, especially when comparing cements ground with different grinding equipment.

In both finenesses, the percentage of 45-181m residue was determined by alpine sieving apparatus, and this value was considered as a criterion in categorizing types of blended cements. the percentage of 45-181m residue for pc with 3200 177 100 cm2g and 4000 177 100 cm2g blaine finenesses were obtained 7 and 2.8 respectively. eight types of ...
The fineness of cement can be measured either by the grain size of cement or by the surface area of cement. followings methods are used to determine the fineness of cement. the sieve test- measures a grain size of cement. the blains air permeability test- measures a surface area of cement.
