Abstract:
1. A papermaking raw material processor, said papermaking raw material processor comprising: a processing unit adapted to supply a suspension containing a papermaking raw material and to generate cavitation; a pump adapted to generate pressure to supply the suspension into the processing unit; said processing unit including a jet that receives the suspension from said pump, said jet adapted to create a jet stream of the suspension and to generate cavitation bubbles with the jet stream, said jet further adapted to bring the cavitation bubbles into contact with the papermaking raw material in suspension to process the papermaking raw material with intensive impact from collapse of the cavitation bubbles; and a supply tank adapted to store the suspension, wherein the suspension is supplied from the pump via the jet into the processing unit to feed the papermaking raw material to downstream steps or to return the papermaking raw material to the supply tank.
