Blaine testing machine or SSA (Specific Surface Area) is a dry-powder particle size analyzer. Employing the principle of Air Permeability, this machine is simple to operate and produces quick results for a range of powders in the 0.2–75 micron range. This is a generational update on the venerable Fisher model, which has seen service in the concentrate, cement, and other industries since its development. The water manometers and manual rack-and-pinion systems have been replaced with modern gas control devices and a servo-controlled ball-screw assembly. The system is automated through a touch-screen interface with an intuitive menu interface.
