Njerwa zochepa zomwe zimayambira chitoliro cha mpweya wotentha

Mitundu yonse yazinthu zopangira zokongoletsa, mapangidwe oyengera makonda ndi zojambula

Ubwino wazogulitsa: kutentha kwakukulu kosungira, kutentha pang’ono ndi zina.

Kugwiritsa ntchito kwazinthu: yoyenera kuthandizira ng’anjo yotentha ndi ng’anjo zaphulika zapakati ndi zazing’ono.

Mafotokozedwe Akatundu

Njerwa zotsika pang’ono zopangira timipweya tating’onoting’ono timapangidwa ndi bauxite clinker ngati chopangira chachikulu, chowonjezeredwa ndi zowonjezera zina, zopangidwa ndi kuthamanga kwambiri, ndikuwotcha kutentha kwambiri. Ili ndi maubwino osungira kutentha kwakukulu komanso kutsika pang’ono.
