水泥工業(yè)是耗能大戶，它面臨著節(jié)能降耗的艱巨任務(wù),特別是現(xiàn)今的新型干法水泥生產(chǎn)線，規(guī)模越來越大，節(jié)能空間也越來越大，全廠的風(fēng)機(jī)裝機(jī)容量約占全廠總裝機(jī)功率的30－40%，耗電量約占整個(gè)廠用電量30%－40%；隨著輥式磨系統(tǒng)越來越多地被采用，風(fēng)機(jī)耗電占總耗電量的比重也越來越大。風(fēng)機(jī)的選型是按照滿負(fù)荷狀態(tài)設(shè)計(jì)的，而實(shí)際生產(chǎn)過程中隨工況和產(chǎn)量的變化，會(huì)引起風(fēng)量、風(fēng)壓隨機(jī)調(diào)整，眾所周知風(fēng)機(jī)是屬于平方率負(fù)載，如將風(fēng)機(jī)的傳動(dòng)系統(tǒng)換成交流調(diào)速系統(tǒng)，通過調(diào)整電機(jī)轉(zhuǎn)速，滿足風(fēng)機(jī)的不同工作狀態(tài)下的風(fēng)量和風(fēng)壓，就能把消耗在檔板和閥門上的能量節(jié)省下來，節(jié)能空間和效果是很可觀的，京蘭三源水泥有限公司是一條2000T/D的水泥生產(chǎn)線，其生料磨循環(huán)風(fēng)機(jī)電機(jī)為10KV/630KW，采用擋板（閥門）調(diào)節(jié)風(fēng)量大小，風(fēng)機(jī)消耗功率大，節(jié)流損失較大。調(diào)節(jié)風(fēng)門擋板控制風(fēng)量，由于擋板處于較高壓力下工作，易磨損，易造成管道內(nèi)風(fēng)量調(diào)節(jié)不準(zhǔn)確，對(duì)生料磨系統(tǒng)工藝影響也較大。
生料磨循環(huán)風(fēng)機(jī)在生料磨系統(tǒng)中起到很大作用，通過調(diào)節(jié)循環(huán)風(fēng)機(jī)可以控制磨系統(tǒng)的以下參數(shù)：
1、磨內(nèi)通風(fēng)量：立磨靠風(fēng)掃磨，通風(fēng)量要適當(dāng)。風(fēng)量不足，合格的生料不能及時(shí)帶出，料層增厚，排渣量增多，設(shè)備負(fù)荷高，產(chǎn)量降低；風(fēng)量過大，料層過薄，影響磨機(jī)穩(wěn)定運(yùn)轉(zhuǎn)。
2、料層厚度：立磨穩(wěn)定運(yùn)轉(zhuǎn)的另一重要因素是料床穩(wěn)定。料層穩(wěn)定，風(fēng)量、風(fēng)壓和喂料量才能穩(wěn)定，否則就要通過調(diào)節(jié)風(fēng)量和喂料量來維持料層厚度。若調(diào)節(jié)不及時(shí)就會(huì)引起震動(dòng)加劇，電機(jī)負(fù)荷上升或系統(tǒng)跳停等問題。
3、磨機(jī)振動(dòng)：振動(dòng)是輥式磨機(jī)工作中普遍存在的一個(gè)現(xiàn)象,合理的振動(dòng)是允許的,但若振動(dòng)過大，則會(huì)造成磨盤和磨輥以及襯板的機(jī)械損壞。
4、磨內(nèi)壓差：壓差是指風(fēng)環(huán)處的壓力損失,在磨機(jī)運(yùn)行時(shí)，磨內(nèi)負(fù)荷量的變化不僅從磨機(jī)電流、料層厚度、振動(dòng)幅度等參數(shù)上反應(yīng)出來，而且壓差更能反映磨內(nèi)狀況。
5、磨機(jī)出口溫度：有效的控制出口溫度，可以保持良好的烘干及粉磨作業(yè)條件。
6、產(chǎn)品細(xì)度：磨內(nèi)通風(fēng)量的大小對(duì)產(chǎn)品細(xì)度也有一定影響。
另外磨的運(yùn)行穩(wěn)定因素還有喂料量、噴水量、研磨壓力、循環(huán)風(fēng)量和選粉機(jī)轉(zhuǎn)速等參數(shù)。
