Imishini ye-pellet yezinkuni ithandwa kakhulu manje, futhi abatshalizimali abaningi bathenge imishini yokukhiqiza umshini we-pellet, kodwa umsebenzi womshini we-pellet wokhuni ngezinye izikhathi ukhiqiza isiteji somthwalo we-overload phenomenon ngenxa yezinguquko zezinto zokusetshenziswa, umswakama noma izinga lokushisa. Uma umshini uvinjiwe ngenxa yokulayisha ngokweqile, u-opharetha ngokuvamile uvula inkinobho yokulawula umnyango we-bypass lapho ukugcwala kwamanje kubonwa, ukuze impahla engenayo igeleze iphume ngomnyango we-bypass, bese ivala lapho i-current iwa ibuyela kunani elivamile.

Ukulawula okuzenzakalelayo kwezinkinga zokuphepha komshini we-pellet.
Umgomo wokulawula wendlela yokukhipha okuzenzakalelayo yomnyango we-bypass ufana nenqubo engenhla. Uma isikhungo sokulawula sithola ukuthi i-current yangempela idlula inani elibekiwe, izonikeza isignali yokuvula ku-valve ye-solenoid kumnyango wokudlula olawula ukunwetshwa nokufinyezwa kwesilinda. Umnyango ube usuvulwa yi-cylinder, okuphakelayo kugeleza kuphume, ama-current drops, bese umnyango we-bypass uvale ngokuzenzakalelayo. Inqubo yokulawula okuzenzakalelayo engenhla igwema isenzakalo sokuvinjwa komshini okungenzeka noma nini emshinini we-pellet, futhi ayisadingi ukuthi opharetha aqhubeke ebuka ushintsho lwamanje endaweni, okunciphisa umsebenzi wabantu.
Uhlelo lokuvikela oluzenzakalelayo lokucindezela i-roller ne-ring die Ukuze uvimbele amabhulokhi ensimbi noma okunye ukungcola okukhulu okuqinile ukuthi kungangeni phakathi kwe-roller ecindezelayo nendandatho futhi kubangele umonakalo ku-roller ecindezelayo kanye nokufa kweringi, iphinikhodi yokuphepha noma i-hydraulic hoop isethwe ngokukhethekile ekugcineni okungemuva kwe-shaft eyinhloko. Thayipha indlela yokuvikela ukuphepha, lapho umshini we-pellet we-sawdust ugcwele kakhulu, amandla okugunda wephinikhodi yokuphepha noma amandla okushayisana kwepuleti le-friction kanye ne-friction disc ku-hoop yeqiwe. Ngalesi sikhathi, iphinikhodi yokuphepha iyasikwa noma i-friction disc iyazungeza, futhi inkinobho yokuphepha iyacushwa. Isenzo, futhi isignali yesenzo idluliselwa esikhungweni sokulawula, futhi isikhungo sokulawula sithumela umyalo wokumisa, ukuze kuvikelwe i-roller ecindezelayo futhi indandatho iyafa.

Ukuze uvimbele ibhande ukuthi lingasheleli, ukunciphisa ukusebenza kahle kokudlulisela nokushisa ibhande, inzwa yesivinini ingafakwa ku-pulley eqhutshwayo ukuzwa ijubane le-pulley.

Lapho ibhande lishelela ngemva kokukhululeka, isivinini sokujikeleza se-pulley eqhutshwayo sizokwehla. Uma ingaphansi kwesivinini esivamile sokujikeleza ngenani elithile, ngokuvamile isethelwa ku-90%~95% yenani elivamile. Ukuvalwa kukagesi ukuvimbela ukutubeka kwebhande.
