Thaum cov neeg siv khoom siv hluav taws xob txuag hluav taws xob thiab ib puag ncig tus phooj ywg ntoo crushers los ua cov ntoo chips, qee qhov siv ntoo ntub rau kev ua, thaum lwm tus siv ntoo qhuav rau kev ua cov ntoo chips. Lub dryness thiab av ntawm cov ntoo ncaj qha cuam tshuam rau kev sib tsoo thiab kev tsim muaj peev xwm ntawm ntoo hmoov tshuab. Cov neeg siv khoom zoo heev ntawm kev ziab ntoo thaum tseem ziab nws hauv lub hnub thiab tom qab ntawd crushing nws, uas yuav txhim kho cov nyhuv crushing. Cov av noo ntau dhau ntawm cov ntoo ib puag ncig tuaj yeem yooj yim thaiv txoj kab uas hla ntawm cov hlau tsis muaj hlau mesh thaum lub sijhawm ua haujlwm ntawm lub tshuab ntoo hmoov, ua rau nws nyuaj rau kev txiav thiab ua rau kev ua haujlwm tsis zoo. Cov av noo nyob rau hauv ib puag ncig ntoo yog siab dhau lawm, thiab kev siv mus sij hawm ntev tuaj yeem cuam tshuam cov khoom puas thiab corrosion. Yog li ntawd, txhawm rau txhawm rau ua kom nws lub neej ua haujlwm tau zoo, nws yog qhov zoo tshaj los ua kom qhuav kev kho mob ntawm cov ntoo thiab tseem cua qhuav nws. Yog tias cov av noo nyob rau hauv ib puag ncig ntoo siab dhau lawm, cov ntoo ua los ntawm nws yog ib qho yooj yim rau kev hloov pauv zoo yog tias tsis daws raws sijhawm.
Raws li ib txwm muaj, thaum ua cov ntoo ntub dej, cov khoom siv ntawm cov ntoo uas raug ntaus los ntawm rauj ntawm tsob ntoo crusher yog tag nrho cov fiber ntau. Yog tias muaj fiber ntau, nws yuav cuam tshuam rau kev ua haujlwm ntawm lub rauj, ua rau kev ua haujlwm qis dua thiab ntau qhov ntim me me. Yog tias cov ntoo qhuav raug xaiv, cov fibers sab hauv yuav tsawg dua, thiab cov rauj thiab cov hniav yuav yooj yim tawg cov khoom siv raw, uas tuaj yeem tawg cov ntoo zoo dua thiab ua tau raws li qhov yuav tsum tau ua. Yog tias cov ntoo ntub tau ua rau hauv cov ntaub pua plag ntoo siv lub tshuab hmoov ntoo, cov nyhuv yog qhov zoo dua li cov ntoo qhuav, yog li ua cov ntoo chips tseem nyob ntawm hom raw khoom.
