About Blaine Air Permeability Apparatus

Specification:

Designed to find out specific gravities of semi liquids like mud and other liquids having densities in the range 0.8 to 2.5. It has a stainless steel bam calibrated specific gravities from 0.8 to 2.5. A stainless steel cup with lid and overflow vent is fitted on one side of the beam. A counter weights with cursor slides over the graduated scale. The beam has a knife-edge at centre which rests in a fulcrum fitted in the stand. Leveling screws and spirit level are fitted to the stand.

Spares & Accessories (On Extra Cost) :

Punch to cut filter paper discs. Non-perforated disc. Suction bulb, Mercury

Suitable for samples weighing 2-4 grams, users get immediate readings for efficient analysis and quality control.

Robust and Practical Construction

Built with transparent borosilicate glass for visibility and a sturdy powder-coated metal stand, the device promises longevity and easy maintenance. Its compact, dismantlable design enables straightforward cleaning, and all required sample preparation tools are included for smooth operation.

FAQ's of Blaine Air Permeability Apparatus:

Q: How is the fineness of cement measured using the Blaine Air Permeability Apparatus?

A: The apparatus measures fineness by determining the specific surface area of cement powder. Ambient air is drawn through a standardized permeability cell containing a compressed sample, and the flow rate is measured using a U-tube manometer, yielding the specific surface area in cm2/g.

Q: What accessories are included with the Blaine Air Permeability Apparatus, and how are they used?

A: The apparatus includes a permeability cell, U-tube manometer with glass scale, rubber aspirator, filter paper, weighed sample tube, and sample preparation tool. These accessories facilitate accurate sample containment, air movement, and extraction of results.

Q: When should the Blaine Air Permeability Apparatus be calibrated, and how is calibration performed?

A: Periodic calibration is recommended, especially before a critical series of tests. Calibration involves using reference cement with known fineness to verify the apparatus readings and make necessary adjustments for optimal accuracy.

Q: Where can the Blaine Air Permeability Apparatus be installed and used?

A: It is designed for bench-top mounting in laboratories, cement manufacturing plants, research facilities, and educational institutions. Its compact design allows for convenient placement on standard laboratory benches.

Q: What is the process for preparing a sample for fineness testing?

A: A sample of cement weighing between 2 to 4 grams is carefully prepared using the included tool and filter paper, ensuring homogeneity. The sample is placed in the permeability cell, assembled according to instructions, and then subjected to testing as per standards.

Q: How does the Blaine Air Permeability Apparatus benefit laboratory users and cement manufacturers?

A: Users benefit from reliable, accurate measurement of cement particle fineness, aiding in quality control and compliance with international standards. Its easy operation, low maintenance, and immediate response time streamline laboratory workflow and improve productivity.

Q: Is the apparatus suitable for testing powders other than cement?

A: Yes, while optimized for cement, the Blaine Air Permeability Apparatus can be used to measure the specific surface area of other similar powders within the given capacity and measuring range.
