Njengamanje, imakethe inikeze ubuchwepheshe obukhethekile be-fly ash obushisa umshini wezitini wamahhala, ingadlala ubuchwepheshe ukuze kuzuzwe iningi lokukhiqizwa kwefekthri, ukugaywa kabusha kanye nokusetshenziswa kwe-residual waste fly ash, lezi zimpukane zomlotha zizokhishwa zibe yisimo, ekugcineni zakhiwe, izitini ukuze zibone ukusetshenziswa kabusha kwemakethe. Khona-ke kulolu hlobo lomshini wezitini ukuthi ungadlala kanjani indima, ngoba inqubo yokusetshenziswa kwayo inesifinyezo esilandelayo.

Okokuqala, sidinga i-crusher ukuze sichoboze i-quicklime. Okwesibili, sidinga ukubeka lezi zinto zokusetshenziswa emshinini wokugaya ukuze ugaye ngokucophelela. Ngesikhathi esifanayo, udoti oqinile wezinto zokusetshenziswa, njengomlotha wempukane, ziyamataniswa ngokwesayensi futhi zilinganiselwe. Ekugcineni, afakwa kurola ukuze agingqike ngokucophelela, ngemva kwalokho angafakwa kweminye imishini yokwenza izitini ukuze akhe futhi acindezelwe. Vele, ngemuva kokubunjwa nokucindezelwa, idinga ukomiswa cishe izinsuku eziyi-10. Ngemva kokumiswa ngempumelelo, ingathengiswa emakethe. Ngakho-ke, ubuchwepheshe bomshini wezitini ovuthayo we-fly ash buhle kakhulu, obungakwazi ukubona ukusetshenziswa okuphezulu komlotha wempukane. Ingasetshenziswa njengenye yamafomula wezinto ezingavuthiwe ukuze ubone ukugaywa kabusha futhi. Ngaphezu kwalokho, izinga lokusetshenziswa liphezulu uma kuqhathaniswa, futhi ukungcola komlotha wezimpukane kuphathwa ngendlela enengqondo.
