ABSTRACT:
An apparatus for determining the fineness index of mineral fibers, designed to deliver the micronaire value of fibers. The apparatus includes a device for measuring the fineness index provided with at least a first orifice connected to a measurement cell configured to hold a specimen of a plurality of fiber and provided with a second orifice connected to a device for measuring a differential pressure, on either side of the specimen. The device measuring the differential pressure is configured to be connected to a device for producing a fluid flow. The device for measuring the fineness index also includes at least one flowmeter for measuring the volume flow rate of the fluid passing through the cell.
