Pulp beating freeness tester
Pulp beating (refining) freeness tester is used to measure the rate of dilution of pulp suspended water materials and to determine de-watering time. It is adopted with spring pre-tightening mechanism keeps the rubber sealing ring of the sealing hammer body in contact with the bottom of the water filtering tube. This increases the sealing performance of the sealing hammer body.
