從石灰粉電石生產談高壓壓球機:石(shi)(shi)(shi)(shi)灰(hui)(hui)粉(fen)(fen)通(tong)過高(gao)壓(ya)壓(ya)球(qiu)機成球(qiu)用于生(sheng)產電(dian)石(shi)(shi)(shi)(shi)在電(dian)石(shi)(shi)(shi)(shi)公司取得成功。使得石(shi)(shi)(shi)(shi)灰(hui)(hui)的(de)(de)石(shi)(shi)(shi)(shi)灰(hui)(hui)石(shi)(shi)(shi)(shi)單(dan)耗與焦(jiao) 炭單(dan)耗顯著下降，在大(da)幅降低石(shi)(shi)(shi)(shi)灰(hui)(hui)生(sheng)產成本的(de)(de)同(tong)時。實現了電(dian)石(shi)(shi)(shi)(shi)生(sheng)產“三廢”——石(shi)(shi)(shi)(shi)灰(hui)(hui)粉(fen)(fen)末(mo)的(de)(de)綜合(he)利用。 電(dian)石(shi)(shi)(shi)(shi)生(sheng)產工藝對(dui)投(tou)爐原(yuan)材料粒度(du)有(you)特殊要求，石(shi)(shi)(shi)(shi)灰(hui)(hui)在投(tou)爐前必須進行篩分．以(yi)(yi)分離5 inln以(yi)(yi)下的(de)(de)石(shi)(shi)(shi)(shi)灰(hui)(hui)粉(fen)(fen)末(mo)．從而(er)保(bao)證電(dian)石(shi)(shi)(shi)(shi)爐安全、穩定(ding)、優(you)質、高(gao)產。統計表明，篩下的(de)(de)石(shi)(shi)(shi)(shi)灰(hui)(hui)粉(fen)(fen)末(mo)量(liang)占(zhan)投(tou)爐石(shi)(shi)(shi)(shi)灰(hui)(hui)量(liang)的(de)(de)10％～15％．電(dian)石(shi)(shi)(shi)(shi)生(sheng)產廠家一(yi)般(ban)都(dou)將其作為(wei)三廢處理(li)(li)掉 石(shi)(shi)(shi)(shi)灰(hui)(hui)粉(fen)(fen)末(mo)的(de)(de)利用問題一(yi)直被電(dian)石(shi)(shi)(shi)(shi)行業(ye)所關注。到目前為(wei)止，國(guo)內較成熟的(de)(de)工藝是將石(shi)(shi)(shi)(shi)灰(hui)(hui)粉(fen)(fen)作為(wei)炭化焦(jiao)球(qiu)的(de)(de)粘接劑而(er)加(jia)以(yi)(yi)綜合(he)利用．但其生(sheng)產工藝占(zhan)地面積(ji)大(da)、環(huan)保(bao)治理(li)(li)難(nan)度(du)高(gao)、使用效果(guo)不理(li)(li)想，未在行業(ye)內推廣。另外，隨著20世(shi)紀末(mo)國(guo)內引進空(kong)心(xin)(xin)電(dian)極技術．有(you)極少數廠家將石(shi)(shi)(shi)(shi)灰(hui)(hui)粉(fen)(fen)通(tong)過空(kong)心(xin)(xin)電(dian)極加(jia)入電(dian)石(shi)(shi)(shi)(shi)爐而(er)加(jia)以(yi)(yi)綜合(he)利用．但因。
