Uluhlu lokuvula lwe-pellet lokufa olusetyenziselwa izinto zepellet zokhuni luphakathi kwe-5.0-18.0mm, kwaye umlinganiselo wobude, okanye umlinganiselo woxinzelelo, uphakathi kwe-1: 4-1:10.
Umlinganiselo wokunyanzeliswa komsesane wokufa kumatshini wepellet womthi umiselwa ngokwezinto ezikrwada.Umlinganiselo wokunyanzeliswa kwezinto ezikrwada ezahlukeneyo zahlukile, izinto ezilukhuni ekrwada, umlinganiselo omncinci woxinzelelo;I-fluffier ekrwada, umlinganiselo omkhulu wocinezelo. Oko kukuthi, imathiriyeli ekrwada yefluffier kulula ngakumbi ukuyicofa kwaye yenze imilo, imathiriyeli ekrwada yefluffier iqulathe ifayibha eninzi, equlethe imathiriyeli yefayibha engaphezulu kulula ukuyibumba.
