Description
" Rotor voor een inrichting voor de bereiding van vezelbrij voor het bekomen van papier of karton. "
De uitvinding betref t een verbeterinc van een rotor die roterend wordt aangedreven in een kuip o� gesloten ketel waarin oud papi2r, papier- of kartonafval, zuivere vooraf vervaardigde en gedroogde papierdeeg, celstof of houtslijp met toevoeging van water of stoom en eventueel chemikaliën, tot een homogene vezelbrij worden verwerkt die nog andere bewerkingen kan ondergaan om uiteindelijk tot papier of karton te worden verwerkt.
Buiten de inwerking van de toegevoegde stoffen op het droge materiaal, wordt dit materiaal door de rotor gemalen of gebroken, zodat de aanwezige vezels voldoende worden losgemaakt <EMI ID=1.1>
dan voorheen kan gebeuren. Bovendien werd vastgesteld dat doord de werktijd van de inrichting korter wordt, energie voor het aandrijver, van de inrichting wordt uitgespaard en dat wanneer
de inrichting doorlopend werkt, de kapaciteit van de inrichting door de inkorting van de werktijd, toeneemt, zodat in vele
<EMI ID=2.1>
voordeel is dat het in bepaalde gevallen niet meer nodig is
warm water of stoom aan de brij toe te voegen, maar dat het gebruik van koud water volstaat. �ierdoor is tevens een aanzienlijke besparing aan thermische energie mogelijk die anders voor het verwarmen van het water nodig is.
Als voorbeeld, zonder enig begrenzend karakter, volgt hierna een uitvoeriger beschrijving van een verkozen uitvoerings- <EMI ID=3.1>

Het spreekt vanzelf dat de korrels over een gedeelte, over het gehele oppervlak der schoepen of zelfs over geheel de rotor kunnen worden aangebracht en dat de rotor van gelijk welke

"Rotor for a device for the preparation of fibrous pulp for obtaining paper or cardboard."
The invention relates to an improvement of a rotor which is rotatably driven in a tub or # 65533; closed boiler in which old paper, paper or cardboard waste, pure pre-made and dried paper dough, pulp or wood pulp with the addition of water or steam and possibly chemicals, are processed into a homogeneous fiber pulp that can undergo other processes to eventually become paper or cardboard. are processed.
Apart from the action of the added substances on the dry material, this material is ground or broken by the rotor, so that the fibers present are sufficiently loosened. <EMI ID = 1.1>
than can happen before. In addition, it was found that due to the operating time of the device being shorter, energy for the actuator of the device is saved and that when
the device works continuously, the capacity of the device increases due to the shortening of the working time, so that in many
<EMI ID = 2.1>
the advantage is that in certain cases it is no longer necessary
adding warm water or steam to the mash, but using cold water is sufficient. � This also allows for significant savings in thermal energy that would otherwise be needed to heat the water.
As an example, without any limiting character, a more detailed description of a preferred embodiment follows below. <EMI ID = 3.1>

rotor that fines the mass efficiently and in a shorter time than before
<EMI ID = 9.1>
To be welded, they can also be fused into the blades by means of a plasma flame. These granules can also be glued to the blades by means of a suitable resin. Alternatively, another suitable hard granular material can be used instead of carbide grains.
It goes without saying that the granules can be applied over part, over the entire surface of the blades or even over the whole of the rotor and that the rotor of any

what kind of device for producing fiber pulp. For instance, in certain cases this rotor can also be a screw or another grinding element.
