Denderedzwa reMazino Roller Shell
Muindasitiri yekugadzira mapellet, michina ye ring die kana flat die pelleting inowanzo shandiswa kudzvanya zvinhu zveupfu kuti zvipinzwe mupellet feed. Zvese zviri zviviri flat ne ring die zvinotsamira pakufamba kwe pressure roller nedie kuti zvibate chinhu chacho panzvimbo inoshanda uye zvisvinire muchimiro chazvo. Iyi pressure roller, inozivikanwa se pressure roller shell, ndiyo inonyanya kushanda mu pellet mill, sezvinoitwa ring die, uye ndeimwe yezvikamu zvinopfekwa.
Roller yekumanikidza yegranulator inoshandiswa kudzvanya zvinhu mudhiraivha yeringi. Sezvo roller ichinge yave nekukweshwa nekumanikidzwa kwenguva yakareba, denderedzwa rekunze reroller rinogadzirwa kuita migero, izvo zvinowedzera kuramba kwekupfekwa uye zvinoita kuti zvive nyore kubata zvinhu zvakasununguka.
Mashandiro emaroller akashata kupfuura edhiri remhete. Pamusoro pekusashanda zvakanaka kwezvinhu zvakagadziriswa pamaroller, silicate, SiO2 mujecha, mafirita esimbi, nezvimwe zvinhu zvakaoma muzvinhu zvakagadziriswa zvinowedzera kusashanda zvakanaka pamaroller. Sezvo kumhanya kweroller yekumanikidza nedhiri remhete zvakaenzana, dhayamita yedhiri remhete inongopfuura 0.4 chete nedhayamita yemukati medhiri remhete, saka mwero wekusashanda kwedhiri remhete wakakwira ka2.5 kupfuura wedhiri remhete. Semuenzaniso, hupenyu hwedhiri remhete remhete rinotenderera maawa 800, asi nguva chaiyo yekushandisa haisi kupfuura maawa 600. Mune mamwe mafekitori, nekuda kwekushandiswa zvisina kunaka, nguva yekushandisa isingasviki maawa 500, uye maroller akakundikana haachagone kugadziriswa nekuda kwekusashanda zvakanaka pamusoro.
Kupfekwa zvakanyanya kwemaroller hakungoderedzi chete kuumbwa kwemafuta epellet uye kunowedzera mari yekugadzira, asiwo kunokanganisa zvakananga kugadzirwa. Saka, nzira yekuwedzera hupenyu hwebasa remaroller epellet mill inyaya inonyanya kukoshesa indasitiri.
