Akukho mgca wokuvelisa isichumiso owomisayo
Umgca wokuvelisa isichumisi ongasomisiyo luhlobo lomgca wokuvelisa ovelisa isichumisi esixutywe ngaphandle kwesidingo senkqubo yokomisa.Le nkqubo yaziwa ngokuba yi-extrusion granulation kwaye yindlela entsha nesebenzayo yokuvelisa izichumisi ezihlanganisiweyo.
Nalu ulwandlalo oluphangaleleyo lwendlela yokuvelisa isichumiso esidityanisiweyo esingasomisiyo:
1.Ukuphatha impahla ekrwada: Inyathelo lokuqala kukuqokelela nokuphatha imathiriyeli ekrwada.Izinto ezisetyenziswa ekuveliseni isichumiso esixubeneyo ziquka initrogen, phosphorus, kunye ne potassium (NPK) izichumisi, kunye nezinye izinto eziphilayo kunye ne-inorganic ezifana nomgquba wezilwanyana, iintsalela zezityalo, kunye neemveliso eziphuma kwimizi-mveliso.
I-2.Crushing: Izinto eziluhlaza zityunyuzwa zibe ngamaqhekeza amancinci ukuququzelela inkqubo yokuxuba.
3.Ukuxuba: Izinto eziqhekekileyo eziluhlaza zixutywe kunye zisebenzisa umatshini wokuxuba ukwenza umxube we-homogeneous.
I-4.I-Granulation ye-Extrusion: Izinto ezixubileyo zifakwe kwi-granulator ye-extrusion, esebenzisa uxinzelelo oluphezulu kunye ne-screw okanye i-roller ukuxinzelela izinto kwiipellets ezincinci okanye i-5.granules.Iipellets ezikhutshiweyo okanye iigranules zisikwa ngokobungakanani obufunwayo usebenzisa umsiki.
I-6.I-Screening: I-granules ekhutshiweyo ihlolwe ukuba isuse nayiphi na i-oversize okanye i-undersize particles, iqinisekisa imveliso ehambelanayo.
I-7.I-Coating: I-granules ekhuselweyo emva koko ifakwe ngoluhlu lwezinto ezikhuselayo zokukhusela i-caking kunye nokwandisa ubomi bokugcina.Oku kunokwenziwa ngokusebenzisa umatshini wokugquma.
8.Ukupakishwa: Inyathelo lokugqibela kukupakisha iigranule kwiingxowa okanye ezinye izikhongozeli, ezilungele ukuhanjiswa nokuthengiswa.
Kubalulekile ukuqaphela ukuba umgca wokuvelisa isichumiso esidityanisiweyo esingasomisiyo bubuchwephesha obutsha noko kunokufuna izixhobo ezithile kunye noomatshini ukuvelisa iigranuli ezikumgangatho ophezulu.Nangona kunjalo, iingenelo zale nkqubo ziquka ukusetyenziswa kwamandla aphantsi kunye nokunciphisa impembelelo yokusingqongileyo xa kuthelekiswa neendlela zokomisa zendabuko.
Ngokubanzi, umgca wokuvelisa isichumisi ongekho-drying extrusion unokuba yindlela efanelekileyo kunye neyonga imali yokuvelisa izichumisi ezihlanganisiweyo eziphezulu kunye nobukhulu obuhambelanayo kunye nomxholo wesondlo.
