The Pulp Disintegrator (also known as a Standard Fiber Disintegrator
or Fiber Stirrer) is specializ ed laboratory equipment that disintegrates fiber bundles into individual
fibers through high-speed rotation. It is suitable for processes such as hand sheet forming, drainability measurement, and screening sample preparation. It is widely used for the wet disintegration of various materials including pulp, synthetic fibers, and inorganic fibers.
