Pulp slagvrijheidstester

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.

Measurement range: 0 to 100° SR Sealed testing speed: 100 ± 10 mm/s Volume of distilled water: 1000 ± 5 ml Draining time: 149 ± 1 s Residual water volume: 7.85 to 8 ml Hydraulic pressure: >0.3 MPa Dimension: 450x250x1100 mm Net Weight: 40 kg

Pulp beating freeness tester has applications in pulp & paper industry, packaging industry.
