Dothi ndi mwala wamba m'makampani omanga. Zipangizo zambiri zomanga ziyenera kuphwanyidwa mu ufa wabwino asanagwiritsidwe ntchito. Ndiye kodi dothi la dothi limasintha bwanji kuchokera ku ufa wabwino? Pakadali pano, dothi lamiyala kugwedezeka ndipodongomiyala yopukutira miyala zofunika.

Nthaka ndi mwala woponya miyala ndi zida zomwe zimagwiritsidwa ntchito mwapadera pakukukuta dothi, mwala ndi zinthu zina. Pali mitundu yambiri ya dothi ndi mwala wachilengedwe. Madothi wamba amaphatikizapo Kaolin, dongo lopangidwa, dongo, Bentonite, Bauxite, Miyala Yambiri, Yollastonite Minerals Opanda Zitsulo , omwe amapangidwa ndikukonzedwa kenako amagwiritsidwa ntchito m'makampani, ulimi, metaldurgy, makampani amakampani, Kupanga, Kumanga, Kuteteza Zachilengedwe ndi minda ina.

Dothi kapena mwala ungasandutsidwe ufa wabwino utakonzedwa utakonzedwa ndi dothi la dothi popunthwa ndi chopukusira mwala. Kodi njira yoyendetseradongomiyala yopukutira miyala? Zimaphatikizapo kuphwanya, kupera, kuwunika, kusonkhanitsa, kunyamula ndi mayendedwe. Dwalo lamiyala yopangidwa ndi HCmilling (Guiiin Hongcheng) imatha kukonza ufa womalizidwa ndi ufa wosalala wopitilira 80, ndipo mutha kukonza ufa wa ultra mpaka 2000. Magwiridwe ake amtundu wonse ndi khola. Malinga ndi zinthu zosiyanasiyana zakuthupi, makina opera azikhala okonzeka kuonetsetsa kuti pali mphamvu zambiri.

Ndiye, zimawononga ndalama zingatiMwalamphero? Izi zimatengera kuchuluka kwa nthawi ya mphero. Kuyambira 1 tani mpaka matani 100 pa ola limodzi, mitundu yovomerezeka ya dothi ndi miyala yopunthwa ndi yosiyana, ndipo kuchuluka kwake kumakhalanso kosiyana. Takulandilani kuti mulumikizane ndi US pa intaneti chifukwa cha mawu a HCMINAMING (nthaka ya Guilin Hongcheng) ndi dothi lamiyala.
