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.
BlaineGen Classic is a digital Blaine apparatus for measuring cement, lime, and powder fineness by the air permeability method. It determines specific surface area from controlled airflow through a packed powder bed and follows EN 196-6, ASTM C204, GB/T 8074, and NF P15-403 workflows. Digital timing, calculation support, a Blaine cell set, and simple handling make it practical for routine QC.
BlaineGen Plus is an automated Blaine apparatus for determining cement fineness by the air permeability method. Built for EN 196-6 and ASTM C204 workflows, it automates fluid aspiration, timing, K-constant calibration, and result calculation while using four level sensors for precise manometric fluid control. A 7-inch touchscreen, balance integration, data storage, multilingual interface, and standalone operation improve lab efficiency.
