年(nian)产(chan)50万(wan)吨磷建筑石(shi)粉生产(chan)线采(cai)用(yong)了国内先进的煅烧(shao)工(gong)艺及设备;煅烧(shao)线采(cai)用(yong)预烘干和煅烧(shao)两步(bu)法技术方案,预烘干和煅烧(shao)温度可单独控制(zhi),根据(ju)原材料(liao)的波动进行(xing)调节各(ge)项原材料(liao)按设置自动投料(liao),煅烧(shao)后(hou)的石(shi)粉经均化后(hou)用(yong)气流(liu)输送装置输送到其他车间作为(wei)原料(liao)或(huo)外售。
该生(sheng)产线有以下优(you)势:自动化程(cheng)度高、温度控(kong)制精确(que)全封闭环保设计、余热利用率(lv)高、生(sheng)产能耗低产品质(zhi)量稳(wen)定(ding)。
The production line with an annual output of 500,000 tons of phosphorus building stone powder adopts domestic advanced calcination technology and equipment; the calcination line adopts a two-step technical scheme of pre-drying and calcination. The raw materials are automatically fed according to the settings, and the calcined stone powder is homogenized and then transported to other workshops as raw materials or sold by an air conveying device.
The production line has the following advantages: high degree of automation, accurate temperature control, fully enclosed environmental protection design, high utilization rate of waste heat, low production energy consumption and stable product quality.
磷建筑石(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)粉是磷石(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)经脱水(shui)处理制得的(de),以(yi)半水(shui)硫酸钙( β-CaSO4●1/2H2O)为主要成分,不(bu)预加任(ren)何外(wai)加剂或添加物的(de)粉状胶凝材(cai)料。磷建筑石(shi)(shi)粉可(ke)以(yi)代替天(tian)然石(shi)(shi)膏(gao)(gao)(gao)(gao)(gao),用于(yu)石(shi)(shi)抹灰砂浆(jiang)、石(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)自流(liu)平砂浆(jiang)、石(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)粘(zhan)接砂浆(jiang)、嵌缝石(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)、石(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)砌(qi)块、石(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)条板、石(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)腻子纸面石(shi)(shi)板等建材(cai)产品。
Phosphorus gypsum gypsum powder is a powdered cementitious material prepared by dehydration of phosphogypsum, with calcium sulfate hemihydrate ( β-CaSO4 ● 1/2H2O) as the main component, without any pre-additives or additives. Phosphorus building stone powder can replace natural gypsum for building materials such as stone plastering mortar, gypsum self-leveling mortar, gypsum bonding mortar, caulking gypsum, gypsum block, gypsum strip, gypsum putty paper-faced slate and so on.
