Shitingi imwe na kabiri ya shitingi ikoreshwa muburyo bwo kumenagura imyanda.
Igice kimwe cya shitingi gifite rotor imwe ifite ibyuma bizunguruka ku muvuduko mwinshi kugirango ucagagure plastike mo uduce duto.Bakunze gukoreshwa mubikoresho byoroheje nka firime ya plastike, mugihe moderi iremereye irashobora gukora ibintu bya pulasitike binini cyane nk'imiyoboro n'ibikoresho.
Ibice bibiri bya shitingi bifite rotor ebyiri zifatanije zikorana kugirango zimenagure plastike.Rotor ebyiri zizunguruka ku muvuduko utandukanye kandi ibyuma bishyirwa ku buryo plastiki idahwema gutanyagurwa no kumenagurwa kugeza igeze ku bunini bwifuzwa.Amashanyarazi abiri akoreshwa mubisanzwe bikoreshwa mubikoresho bikaze nka bisi ya plastike hamwe nibikoresho biremereye.
Ubwoko bwombi bwa shredders bufite inyungu zabyo nibibi, guhitamo hagati yabyo rero biterwa nibisabwa byihariye bya porogaramu.Kurugero, shitingi imwe ya shaft ikunda kuba yoroheje kandi igasaba imbaraga nke, mugihe ibice bibiri bya shitingi ikora neza mugucamo ibikoresho bikaze kandi birashobora gutwara imyanda minini.
