Zwick roell testing machines manufactures bsa1 automatic blaine permeability apparatus. These apparatus are useful for determining specific surface area of cements and other powdery products. Blaine value is an index to evaluate the grinding effort in cement plant and properties of cement in the construction. The fineness of the cement is proportionate to the index. The method applied determines the fineness of cement or other products by measuring the elapsed time for a given quantity of air to pass through a compacted bed of cement. The automatic blaine permeability apparatus provides benefits like simplicity/ user friendliness; no calculation; no use of monograph; automatic; several using mode, simple, double and quadruple test and works with variable porosity in an easy way; special diagnostic mode; and automatic calculation of k for calibration.
