Freeness Tester

Various fiber slurries are cut, crushed, rubbed, split, moistened and refined to achieve cell wall displacement and deformation of fibers. Meet ISO 5264/I, TAPPI-T200, GB7980 and other laboratory beating standards, can change the heavy thallium pressure, beating time, and automatically control the beating time to obtain different experimental results.

Specially designed for all kinds of pulp suspensions not greater than 100 ° SR, Measurement range 0~100 ° SR, cone rise speed 100 +/- 10mm/s, overflow discharge time 149 +/- 1s, remaining volume 7.5~ 8.0ml

High-efficiency experimental equipment specially designed for pulp and paper experiments. Widely used in the determination of pulp dissociation, moisture, concentration and wet dissociation, providing standards for pulp samples. Compliant with ISO 5264/2

The frequency-modulated vibration sieve (Somerville type Vibration sieve) is used to sieve impurities in pulp and measure the content of impurities such as fragments in pulp. The use of this sieve in the pulp and paper laboratory can reduce the number of impurities in the pulp suspension that do not meet the process requirements, resulting in clean and good pulp.
