Mtundu wa mafunde umasankhidwa

Ngati mtundu wonyowa sungathe kukwaniritsa zofunikira za kugwiritsidwa ntchito kwa mchenga wouma, mtundu wa mchenga wowuma kapena mtundu wina wamchenga.
Zinthu zotsatirazi ziyenera kuzindikiridwa mukamaganizira kugwiritsa ntchito mtundu wa chonyowa:

Kusanthula mwachindunji: Ngati khoma la kuponyedwa ndi loonda, ngakhale kuti kuponyera mchenga kwambiri, koma chizolowezi chowuma, mchenga womata, moto wothamanga, moto wothamanga, moto wothamanga, moto wothamanga ndi wocheperako. Kuletsa kumeneku kungakhale koyenera koyenera. Chifukwa lisanathe kuthira, ngakhale chipolopolo chachikulu kwambiri chazitsulo chatsika pansi poponyera. Kuphatikiza apo, kugwiritsa ntchito mchenga wapamwamba kwambiri wa sodium kapena kusunthidwa pamchenga wa bentonite, mtundu wake wamchenga wonyowa wonyowa ndiwokwera, chifukwa choponyera pang'ono pamtunda.

(3) Mtundu wamchenga ndi njira yayitali yotsatsira kapena kudikirira kwakanthawi kutsanulira sikuyenera kunyowa. Mwachitsanzo, ma courses ambiri opondereza, nthawi yayitali ya mchenga, nthawi yayitali yotsika komanso kukula kwakukulu kwa kuponyera, mtundu wonyowa udzaumiririka kwa nthawi yayitali, ndikuchepetsa mphamvu zapamwamba komanso zamchenga. Chifukwa chake, mtundu wonyowa uyenera kuthiridwa tsiku lomwelo. Ngati mukufuna kutsanulira tsiku lotsatira, theka la m'munsi mwa bokosi lopanda kanthu liyenera kumangidwa kuti mupewe kutaya madzi. Tsegulani bokosi lisanalowe tsiku lotsatira, tsegulani pakati, kenako kutsanulira bokosilo. Njira zazitali ziyenera kulingaliridwa pamitundu ina yamchenga.
(4) Chitsulo chozizira kwambiri chikaikidwa mu mtundu, mtundu wonyowa uyenera kupewedwa. Ngati pali chitsulo chonyowa, chitsulo chozizira chikuyenera kukhazikitsidwa pasadakhale, ndikuyikanso mtundu wa nthawi, kuti mupewe "madontho amadzi", ndikupangitsa kuti hod hod homor itatsanulira.
Ngati mtundu wonyowa umawonedwa kuti ndi wosadalirika, mtundu wa mchenga wowuma, mawonekedwe amchenga okhawo owuma, malinga ndi kukula kwa kuponyera mabatani ndi kuthira kwa khoma, mpaka 15mm. Ili ndi zabwino zambiri za mtundu wonyowa, koma magwiridwe antchito ndi abwino kuposa mtundu wanyowa, kuchepetsa chizolowezi, mchenga, mchenga, mchenga. Amagwiritsidwa ntchito makamaka pamakina opangidwa ndi makina kapena makina.
Kwa ziphuphu zazikulu, zotumphukira zitha kugwiritsidwa ntchito ku mtundu wolimba wamchenga, mtundu wa mchenga wamchenga ndi mtundu wa mchenga wowuma. Kukula kowoneka bwino, kuponyera kosalala kumatha kupezeka ndi restin, koma mtengo wake ndi wokwera.
