1.1 Mhedziso yekugadzira marasha chirimwa
Iyo Longquan Coal Preparation Plant yeTaiyuan Coal Gasification Company yakakura-yakakura mbiri-system ine dhizaini inokwana 5.00Mt/a iyo inonyanya kugadzira marasha ekubikira uye inofunga nezve kugadzirwa kwemarasha ekupisa.Iyo coarse slime system yemuchina wekugadzira marasha inoita 5% yehuwandu hwekugadzira marasha uye ine huwandu hwekugadzirisa kweawa hwe56.82t / h.
1.2 Kuronga maitiro
Maitiro ekugadzirira marasha mukugadzirwa kwechirimwa chekugadzira marasha ndeaya anotevera: Mushure mekunge marasha akadzikiswa uye akaongororwa (iyo desliming skrini ndeye 1mm), 50 ～1mm inopatsanurwa nedutu rinodonha uye risingaremekedze matatu-chigadzirwa chinorema-yepakati. , 1～0.25mm Iwo marasha akakora anopatsanurwa neTBS, uye iyo -0.25mm yakanaka marasha slime inodzoserwa nekukora uye kusefa muchina sepakati marasha chigadzirwa.
2.1 Kupatsanura uye kudzoreredza maitiro eyakaomarara slime isati yachinja tekinoroji
Iyo yekuparadzanisa uye yekudzoreredza maitiro ehutete hwakaoma pamberi pekushandurwa kwehunyanzvi kweLongquan Coal Preparation Plant ndeye: cyclone concentration + TBS kupatsanurwa + cyclone concentration + arc sieve desliming uye dewatering + centrifuge dewatering.Iyo chaiyo maitiro inoratidzwa muFigure 1.
