bivis roll-style dynofiner is used to deal with wood chip chemical pulp.The power consumed is 20-50% less than fibrator.Moreover,it can fulfil the task of contraction of pulp stock and extration of high-density black liquor while it is doing the work of refining.   It is also used to produce APMP pulp of high whiteness and high intensity.It can be used to replace the MSD and the dipper in the traditional APMP production line to simplify production precess and save investment.Also high-density mixing can be realized by using the machine.   This machine can be used to renovate the traditional chemical or mechanical pulping production line(CMP/CTMP),using less steam or no steam and forming an new-type extrusion pulping production line with this machine as the key equipment.   This machine can be used to prepare bleaching mechanical pulp with such materials as cotton or hemp of long fiber.    This machine can be used as a high-density bleaching mixer.   This machine can be used deal with the adhesive stuff,which is produced in the process of high-density kneading,deinking and dispersing of that type of waste paper that is difficult to be deinked.   This machine can be used to thresh that type of waste paper,which is difficult to be threshed(i.e. it contains a great deal of wet strength agent and a great deal of wet adhesion agent.)
