  滾筒篩沙機(jī)具有功率小,能耗低,筒內(nèi)有自清掃裝置,篩孔不易被堵塞;占用空間小,投資成本降低、運(yùn)轉(zhuǎn)平穩(wěn)可靠、篩分效率高、產(chǎn)量大;工藝布置簡(jiǎn)便,安裝、維護(hù)方便,操作方便等特點(diǎn)。同時(shí)對(duì)物料的適應(yīng)能力強(qiáng),粘性、濕度大、臟、雜等各種性質(zhì)的物料都能篩分,進(jìn)料方式多樣化,即人工方式和機(jī)械傳動(dòng),能大批量生產(chǎn),中心篩網(wǎng)采用環(huán)狀扁鋼圈設(shè)計(jì),耐磨性好,使用壽命長(zhǎng),結(jié)構(gòu)簡(jiǎn)單,維修方便。
滾筒篩沙機(jī)
  滾筒篩沙機(jī)篩分過(guò)程的技術(shù)經(jīng)濟(jì)指標(biāo)是篩分效率和生產(chǎn)率。前者為質(zhì)量指標(biāo),后者為數(shù)量指標(biāo)。它們之間有一定的關(guān)系,同時(shí)還與其他許多因素有關(guān),這些因素決定篩分的結(jié)果。影響滾筒篩沙機(jī)篩分過(guò)程的因素大體可以分三類:
  一、被篩分物料的物理性質(zhì):包括物料本身的粒度組成、濕度、含泥量和粒子的形狀等。當(dāng)物料細(xì)粒含量較大時(shí),篩子的生產(chǎn)率也大。當(dāng)物料的濕度較大時(shí),一般來(lái)說(shuō)篩分效率都會(huì)降低。但篩孔尺寸愈大,水分影響愈小,所以對(duì)于含水分較大的濕物料,為了改善篩分過(guò)程,一般可以采用加大篩孔的辦法,或者采用濕式篩分。物料含泥量大(當(dāng)含泥量大于8%時(shí))應(yīng)當(dāng)采用濕式篩分,或預(yù)先洗礦。
  二、篩面性質(zhì)及其結(jié)構(gòu)參數(shù)的影響:濕料滾筒篩沙機(jī)是使粒子和篩面作垂直運(yùn)動(dòng),所以篩分效率高,生產(chǎn)能力大。而粒子與篩面相對(duì)運(yùn)動(dòng)主要是平行運(yùn)動(dòng)的棒條篩、平面振動(dòng)篩、筒篩等,其篩分效率和生產(chǎn)能力都低。對(duì)于一定的物料而言,篩子的生產(chǎn)率和篩分效率決定于篩孔尺寸。生產(chǎn)率取決于篩面寬度,篩面寬生產(chǎn)率高。篩分效率取決于篩面長(zhǎng)度,篩面長(zhǎng)篩分效率高。一般長(zhǎng)寬比為2。有效的篩子面積(即篩孔面積與整個(gè)篩面面積之比)愈大,則篩面的單位面積生產(chǎn)率和篩分效率愈高。篩孔尺寸愈大,則單位篩面的生產(chǎn)率越大,篩分效率越高。
  三、生產(chǎn)條件的影響:當(dāng)篩子的負(fù)荷較大時(shí),篩分效率低。在很大程度上篩子的和平率取決于篩孔大小和總篩分效率;篩孔愈大,要求篩分效率愈低時(shí),則生產(chǎn)率愈高。給料均勻性對(duì)篩分過(guò)程意義很大。篩子的傾角要適宜,一般通過(guò)試驗(yàn)來(lái)確定。再就是篩子的振幅與振次,這與篩子的結(jié)構(gòu)物性有關(guān),在一定的范圍內(nèi),增加振動(dòng)可以提高篩分指標(biāo)。
滾筒篩沙機(jī)
  用戶盡量多考察幾個(gè)廠家,選擇適合自己的型號(hào)才更重要。作為專業(yè)破碎設(shè)備廠家的華盛銘重工,深入了解用戶需求,早早的就結(jié)合國(guó)內(nèi)外的破碎篩分技術(shù),并融合國(guó)內(nèi)市場(chǎng)情況,生產(chǎn)的這臺(tái)滾筒篩沙機(jī),直接出售給用戶,不經(jīng)中間商。關(guān)于設(shè)備具體的價(jià)格,您可隨時(shí)在線咨詢客服,廠家為您安排專業(yè)人員指導(dǎo)選型,并給出合理報(bào)價(jià)。
