Chemical mechanical pulping ndi njira ya pulping yomwe imagwiritsa ntchito mankhwala pretreatment ndi makina akupera pambuyo mankhwala.Choyamba, konzekerani mofatsa (kuviika kapena kuphika) ndi mankhwala kuti muchotse gawo la hemicellulose pamitengo yamatabwa.Lignin ndi yochepa kapena pafupifupi osati kusungunuka, koma intercellular wosanjikiza ndi anafewetsa.Pambuyo pake, mphero ya disc imagwiritsidwa ntchito pochiza chithandizo pogaya tchipisi tamatabwa (kapena tchipisi ta udzu) kuti tilekanitse ulusi kukhala zamkati, zomwe zimatchedwa chemical mechanical pulp (CMP).
Makina opangira ma screw knotter awiri amagwira ntchito pakukoka tchipisi tamatabwa, tchipisi tansungwi, zida zanthambi, udzu wampunga ndi zida zina.Imatha kupanga mwachindunji zinthu zopangira kukhala ulusi wa velvet, ndipo imatha kupangidwa mwachindunji kukhala zamkati ndi zoyenga zambiri.
Makina opangira slurry knotter amapangidwa makamaka ndi chipinda cha slurry, maziko, chipangizo chodyera, chipangizo chotumizira, mota yayikulu, ndi zina zotere. Galimotoyo ikatsika kudzera mu chochepetsera, slurry imakankhidwira muchipinda chopukutira chonyowa kudzera pa screw, ndipo imasweka. mu ulusi wa velveti pansi pa kupaka mwamphamvu ndi kugaya mbale.Makinawa ali ndi mawonekedwe osavuta, kukhazikitsa kosavuta komanso kukonza kosavuta.
