The Blaine apparatus is a system that is used to determine the particle size of Portland cement, limes and similar powders. The Blaine value is expressed in terms of their specific surface area. The specified surface is determined by measuring the flow of resistivity of air through a porous bed of the dry cement powder. In other words, the Blaine system measures the finesse of the Cement. The specific surface determined by use of a Blaine apparatus is directly related to its rate of reaction. This information is commonly used in the Cement industry to understand the setting speed as well as the strength development of a particular sample. Check out our NextGen Blaine apparatus' below which range from manual systems to fully automatic Blaine systems for higher accuracy.
The fully automatic digital BlaineGenPLUS model is used to determine the fineness and particle size of cement (and other powdery products).
