Page 5: Introduction
Introduction Designated use The FRIABILIMETER is used for determining the friability and whole hyaline of barley malt grains directly after kilning. It mechanically separates a malt sample into hard (glassy) and friable (easily crushed) constituents. The FRIABILIMETER consists of a mechanical abrading device with an electric motor and an electronic timer. -

Page 28: Abrasion On The Drive Rolls
If the diameter is less than Ø 39.0 mm, have the drive roll renewed by a specialist or by Pfeuffer GmbH's customer service (see chapter 9.5 and 9.5.1). Make a note of the renewal, the calibration and the subsequent check with test malt in a test log (see master copy on last page). -
Page 29: Precise Adjustment Using The Setscrew
Disconnect the mains cable from the electrical power supply, or pull out the coupler. There is a plastic cap on the top of the FRIABILIMETER. Under this plastic cap, there is a setscrew inside the housing. This setscrew directly acts on the spring travel and thus on the force exerted on the sieve drum by the pressure roll. -
