Urwego rwa aperture rwurusyo rwa pellet rupfa gukoreshwa mubikoresho bya pellet yimbaho iri hagati ya 5.0-18.0mm, naho uburebure bwa aperture, cyangwa igipimo cyo kwikuramo, kiri hagati ya 1: 4-1: 10.
Ikigereranyo cyo guhunika impeta ipfa kumashini ya pellet yimbaho igenwa ukurikije ibikoresho bibisi.Ikigereranyo cyo guhunika cyibikoresho fatizo bitandukanye biratandukanye, ibikoresho bigoye cyane, igipimo gito cyo kwikuramo;ibikoresho fatizo bya fluffier, igipimo kinini cyo kwikuramo .Ni ukuvuga ko ibikoresho fatizo byoroshye byoroshye gukanda no gukora imiterere, ibikoresho fatizo bya fluffier birimo fibre nyinshi, birimo ibintu byinshi bya fibre byoroshye gukora imiterere.
Mbere ya byose, hashingiwe ku guhitamo impeta yo mu rwego rwo hejuru ipfa, igomba gushingira ku kigereranyo cy’ibikoresho byakozwe, hitamo ifishi ikwiye yo gupfa, igipimo cyo gufungura no kugereranya (compression ratio = uburebure bukomeye bwumwobo wapfuye / diameter ).Hashingiwe ku garanti impeta ipfa imbaraga, uzamure igipimo cyo gufungura impeta ipfa.Ku bwoko bumwe bwibikoresho, ukurikije igipimo cyo kugabanuka gukwiye, urukuta rwimpeta ruba ruto cyane, kuburyo impeta ipfa imbaraga zidahagije, hazabaho guturika mubibumbano mubikorwa, muriki gihe bigomba kuba byemeza ko impeta ipfa umwobo uburebure buringaniye, kongera umubyimba wimpeta bipfa no kongera umwobo wo gutabara.
Ikigereranyo cyo gupfunyika impeta ni igipimo cyuburebure bukomeye bwimpeta yipfa kugera kuri diameter ntoya yumwobo wimpeta, kikaba ari indangagaciro yerekana imbaraga zo gukuramo imashini ya pellet yimbaho.Ingano nini yo guhunika, niko ibiti biva mu biti bikomera.
Hanpai impeta yibanda ku gukemura ibibazo byo guturika impeta n’umusaruro muke mugikorwa cyo gukora ibiti bya pellet.Kandi gukoresha uburyo bwo gukomera birashobora kongera ubuzima bwa serivisi hejuru ya 50%.
