M'zaka zaposachedwa, kupumula kwa mchenga wagwiritsidwa ntchito kwambiri pantchito yopondereza

Mchenga woponyaAmagwiritsa ntchito njira yogwiritsira ntchito zachilengedwe kwambiri, omwe amatha kugawidwa pamchenga wokhala ndi dongo, mchenga wofiyira woponya, ndi mchenga woponyera. Ng'ombe ya mchenga nthawi zambiri imakhala yopangidwa ndi mchenga wakunja komanso pakati (nkhungu). Chifukwa cha mtengo wotsika komanso kupezeka kosavuta kwa zinthu zomwe zimagwiritsidwa ntchitomchenga woponya, komanso kuthekera kwawo kogwiritsidwa ntchito kangapo, pokonza mosavuta, komanso kugwira ntchito mwachangu mumchenga, kwakhala nthawi yayitali pakupanga chitsulo, chitsulo, ndi zolemetsa za batch ndipo kupanga kwakukulu.

Malinga ndi kafukufukuyu, pakadali pano m'makampani ogulitsa apadziko lonse lapansi, 65-75% ya zipsinjo amapangidwa ndikutulutsa nkhungu, ndi maakaunti opanga dongo kwa pafupifupi 70% ya izi. Cholinga chachikulu ndikuti mchenga wotsika mtengo, njira zosavuta zopangira, ndofupi zafupifupi poyerekeza ndi njira zina zolaula, ndipo palinso opanga maluso omwe ali ndi mchenga woponyera. Kotero magalimoto ambiri, makina, makina, magawo a zidabwa, magawo apamsewu, ndi zina zambiri.

Kulemera kwa michere yopangidwa ndi mchenga wobiriwira kumatha kuyambira ma kilogalamu angapo ku ma kilogalamu a makilogalamu, kuponyera nyumba zina zazing'ono komanso zapakatikati, pomwe mabokosi owuma amatha kulemera. Njira zingapo zojambula zamchere zimakhala ndi maulendo apadera, chifukwa choponyera mchenga ndi njira youmba ya mabizinesi ambiri opsinjika. M'zaka zaposachedwa, mchenga wina wogulitsa ku China adaphatikizanso mchenga, mchenga woponya zida zokumba, ndizida zojambula zokhaKuti mukwaniritse mtengo wotsika mtengo, ndi waukulu wopanga ndi kuponyera mitundu yosiyanasiyana.
