maintains a consistency of 20 30 or greater by shredding of the pulp to a finely divided dry granulate dilution to a homogeneous consistency in the medium consistency range can take place exclusively through hydrodynamic effects from the addition of dilution fluid the dilution fluid is added to granulate at a position at which granulate is in free fall in a standpipe and above a level liq lev of diluted pulp in the standpipe a number of nozzles are arranged around the periphery of the stand pipe directed in towards the center of the stand pipe obliquely downwards in the direction of fall of the granulate it is possible through this simplified procedure to avoid completely the conventional dilution screws and this reduces the investment costs and operating costs while at the same time unnecessary mechanical influence of the pulp fibers can be avoided application_number US 98698411 A description fig1 shows a conventional treatment step for cellulose pulp hereafter denoted u201c pulp u201d the pulp is fed by the pump 1 to a mixer 2 in which necessary treatment chemicals are added these treatment chemicals can be for example oxygen gas ozone chlorine dioxide chlorine peroxide pure acid or a suitable alkali for an extraction step or a mixture of these and possibly other chemical or.
