Lub chipper uas txhua leej txhua tus paub yog dav siv nyob rau hauv cov khoom npaj seem ntawm cov txheej txheem ntawm cov ntaub ntawv, ntoo-raws li vaj huam sib luag, pulping thiab lwm yam industries. Nws tseem yog tsim los ntawm lub ntsiab cutter taub hau, casing, chipper hniav thiab tseem ceeb hluav taws xob tswj. Niaj hnub no peb luv luv qhia cov pawg tseem ceeb ntawm cov hniav hauv lub tshuab:
Cov hniav sib npaug yog cov txheej txheem ntawm kev sib tsoo cov hniav thiab cov khoom siv raw hauv ib lub xeev sib npaug, uas yog hu ua cov hniav sib dhos. Nws txawv raws li qhov xwm ntawm cov khoom siv raw, hauv peb txoj haujlwm nws tuaj yeem muab faib ua cov hniav ncaj, thawb-rub hniav thiab rub hniav.
Kev tsim cov hniav rov qab yog ntsuas tawm sab nraud ntawm ntug ntawm cov hniav los ua ib qho 140-160C degree kaum sab xis nrog lub rooj tsavxwm. Chiping yog ua nyob rau sab saum toj ntawm cov khoom hauv cov hniav ncaj thiab thawb-rub hniav txoj kev.
Muaj qee yam kev ua haujlwm tseem ceeb rau kev rub-rau-slice hauv lub tshuab. Cov khoom siv raw nkag mus rau hauv riam ntug ntawm sab xis, thiab riam ntug yog rub los ntawm sab nraub qaum kom hlais cov khoom nyoos ua ntej.
Cov hniav ncaj yog ua kom cov hniav sib npaug mus rau cov khoom siv raw, thiab cov riam qis yog nqa tawm ntawm txoj cai kawg, thiab kev sib txuas ua ntej yog khaws cia. Lub zog yog khaws rab riam mus rau qhov kawg, thiab qhov taw tes ntawm lub ntiajteb txawj nqus kuj nyob nruab nrab ntawm rab riam.
Kev ua haujlwm ntawm lub laub-rub hniav yog muab qhov tseem ceeb ntawm cov khoom siv raw rau hauv cov hniav. Tom qab cov hniav nkag mus, thawb nws mus rau pem hauv ntej, ua rau tib yam, thiab tom qab ntawd rub nws rov qab. Qhov no tuaj yeem rov ua dua ob peb zaug thaum kawg txiav cov khoom siv raw rau hauv daim. Ib txoj hauv kev yog ua cov ntawv hauv qab ntawm cov khoom siv raw.
Thaum yuav khoom, koj yuav tsum xub saib lub zog cua ntawm cov hniav nws tus kheej, uas ncaj qha nyob ntawm qhov zoo ntawm cov hniav. Muaj ib-edged thiab ob-edged. Ib-edged hniav tuaj yeem yooj yim txiav cov khoom xyaw rau hauv daim. Ob-edged sawv daws yuav zoo rau cov ntaub ntawv nyuaj. Nyob ntawm lub kaum ntse ntse ntawm cov hniav yog txiav. Qhov no ua kom zoo zoo thiab txo kev siv hluav taws xob. Raws li ib txwm muaj, nws txaus los hloov nws txhua ob lub lis piam.
