GB/T 29287-2012 "Pulps - Laboratory beating - PFI mill method" specifies the method for laboratory beating of pulp using a PFI mill, which is applicable to various types of pulp. After mixing the bone-dry pulp sample with water, it is placed in the PFI mill and beaten according to the specified number of revolutions and load. Parameters such as pulp consistency, beating revolutions, and disc clearance are clearly controlled. After beating, the freeness or drainage performance of the pulp is measured, simulating the industrial beating process to provide data support for paper formulation development and process optimization.
