Kupanga malo osagwira dzimbiri m'deralo omwe amalumikizana ndi mpweya wotentha wa chowotcha chachitsulo chosungunula, magawo ofanana a nkhungu amaponyedwa ndi kutsuka kwakuda komwe kumakhala ndi chinthu cholumikizira, makamaka 40- 50% ferrosilicon, yomwe imasinthira m'mphepete mwa chitsulo chosalimba chomwe sichinakhazikike pakhungu loponyera dzimbiri
Kufunika kowongolera zopangira ndikofunikira kwambiri pakupanga kuponyera kwazitsulo kuchokera kuma greensand. Mchenga wapansi wa silika nthawi zambiri umanyalanyazidwa ndi cholinga chachikulu pazowonjezera za bentonite. Zowonjezera za Carbonaceous zitha kuonedwa ngati "zoyipa zoyenera" kuti zitsimikizire kumaliza kwapamwamba ndikuchepetsa zolakwika zam'mchenga. Zowonjezera zina zimagwiritsidwa ntchito makina akakhala kuti sanasinthe ndipo nawonso amawonjezeranso zovuta kumachitidwe a greensand. Pazipangizo zomwe zimafunikira ma cores iyi imakhala nkhani yayikulu chifukwa makina angapo amtundu wa resin amagwiritsidwa ntchito popanga zinthu zoyambirira ndipo izi zimayenera kuganiziridwa pakuwongolera magawo onse am'mlengalenga komanso kuwongolera mchenga wonse.
Mapasa azowonjezera kaboni ndi kutayika-poyatsira komanso kuwunikira mchenga wonse amafunika kumvetsetsa ndi kuwongolera mosamala. Njira zingapo zowongolera zimayesedwa kuphatikiza njira zachikhalidwe monga kuphulika ndi kutaya poyatsira pamodzi ndi njira zotsimikizika za bentonite ndi njira zosanja. Njira zatsopano zowongolera monga kaboni wathunthu zimawunikiridwa limodzi ndi njira zonse zoyesera ndikuwongolera.
Njira zingapo zolosera zimawonedwanso ngati njira yolamulira. Ubwino wa zowonjezera komanso ntchito yawo komanso koposa zonse kulumikizana kwawo kukuwonetsedwa, chifukwa ili ndi dera lomwe nthawi zambiri limanyalanyazidwa pomwe amuna oyambira amayesetsa kuti achite bwino pamasewera osasintha. Mayeso oyeserera omwe akubwera amakambidwa mogwirizana kuti awonjezere pa chosakanizira.
Zowunikiranso ndikumasulira kwa zotsatira ndi zomwe zimafunika kuti zitsimikizidwe ndikuwongolera zomwe zimapangitsa kuti magwiridwe antchito azigwiritsa ntchito poyang'ana kumvetsetsa ndikuwongolera zowonjezera zowonjezera pakuponya magwiridwe antchito
