1、礦山石料廠原料破碎系統除塵器對原料礦、塊礦以及石灰石、白云石、鋁土、原煤等原料的破碎機或粉碎機的投料口﹑出料口、振動篩上部以及帶式輸送機轉運點等部位設密閉裝置或集塵罩，轉運點受料處宜設雙層密閉罩。
將產塵設備用密閉罩罩起來，或制作收塵小室，使罩內形成均勻負壓，避免粉塵外逸，或用敞口吸氣罩形成吸捕氣流，將暴露的塵化區控制在狹小范圍內，使攜塵氣流被吸捕抽走，通過除塵器凈化后經排氣筒(或煙囪)排入大氣。
2、混勻配料槽的槽上卸料車和槽下定量給料工位應采取除塵措施。槽上卸料車產生的粉塵可采用移動風口通風槽或車載式除塵器，或設大容積密閉罩。對槽下定量卸料裝置產生的粉塵宜設雙層密閉罩。對混勻配料槽揚塵，宜設獨立的干式除塵系統，采用袋式除塵器。
3、原煤破碎輸送除塵系統應采取專業措施。除塵器選用袋式除塵器，除塵布袋應具有防靜電功能；系統和設備應靜電接地，并設泄爆裝置。灰斗宜采取保溫或伴熱措施。
4、原(yuan)料堆場的(de)抽風除塵(chen)(chen)(chen)(chen)(chen)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)包括礦石破碎、篩(shai)(shai)分(fen)(fen)除塵(chen)(chen)(chen)(chen)(chen)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)，石灰(hui)石破碎、篩(shai)(shai)分(fen)(fen)除塵(chen)(chen)(chen)(chen)(chen)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)，鋁礦石破碎除塵(chen)(chen)(chen)(chen)(chen)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)，以及煤破碎除塵(chen)(chen)(chen)(chen)(chen)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)等(deng)。對(dui)于(yu)產(chan)(chan)塵(chen)(chen)(chen)(chen)(chen)設備集(ji)中(zhong)、粉塵(chen)(chen)(chen)(chen)(chen)性質相同和工作制度相同的(de)產(chan)(chan)塵(chen)(chen)(chen)(chen)(chen)點，盡量采用(yong)(yong)(yong)大的(de)集(ji)中(zhong)除塵(chen)(chen)(chen)(chen)(chen)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)，便于(yu)管(guan)理(li)，如石灰(hui)石破碎、篩(shai)(shai)分(fen)(fen)除塵(chen)(chen)(chen)(chen)(chen)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)多(duo)達幾(ji)十個產(chan)(chan)塵(chen)(chen)(chen)(chen)(chen)點集(ji)中(zhong)在一個大系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)中(zhong)。否(fou)則可以采用(yong)(yong)(yong)小型的(de)分(fen)(fen)散系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)。各種除塵(chen)(chen)(chen)(chen)(chen)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)中(zhong)多(duo)采用(yong)(yong)(yong)干式高效袋式除塵(chen)(chen)(chen)(chen)(chen)器(qi)。
