Application:

BN-8055 Pulp Canadian Standard Freeness CSF Tester (pulp freeness tester) for the determination of pulp freeness. It is widely used for the change of filterability of various chemical pulps in the process of beating and refined pulp. In the process of pulp processing, a large number of fine fibers will be produced, and sometimes the freeness will increase abnormally (false freeness), the value is less than 100ml. The freeness value is not necessarily related to the drainage performance of the pulp on the paper machine.
