    摘要:

    針對(duì)電解法制鈦工藝中陰極產(chǎn)物(200 kg/d)處理過程出現(xiàn)的產(chǎn)品污染問題,自行設(shè)計(jì)了鈦質(zhì)球磨裝置,并對(duì)工藝參數(shù)進(jìn)行了研究。設(shè)計(jì)的球磨裝置容積為320 L,直徑及高度均為1 080.9 mm,處理能為148.3 kg/h,需1臺(tái)功率為5 kW的電機(jī)。在球磨轉(zhuǎn)速為35 r/min、大中小(直徑分別為50、30、20 mm)3種磨球質(zhì)量比為1∶1∶2、液固比為4∶1和填充率為50%條件下球磨25 min后,獲得的鈦粉質(zhì)量可達(dá)到行業(yè)標(biāo)準(zhǔn)YS/T 654—2007中的TF-2級(jí)別,且粒徑分布與實(shí)驗(yàn)室洗滌鈦粉相當(dāng)。自行設(shè)計(jì)的鈦質(zhì)球磨裝置能夠滿足中試規(guī)模金屬鈦粉后處理的需求。

    Abstract:

    To solve the production contamination problems occurring during the processing of cathode products in the titanium production by electrolysis(200 kg/d), a special titanium ball mill was designed and its technical parameters were studied. The results show that the titanium ball mill is designed as a cylinder and its size is 1 080.9 mm both for the diameter and height(about 320 L). The processing capacity of this equipment can reach 148.3 kg/h and its motor power needs 5 kW. When the condition of ball-milling speed, mass ratio of three sizes ball(small, medium and large), liquid-solid ratio, fill rate and ball-milling time are 35 r/min, 1∶1∶2, 4∶1, 50% and 25 min, respectively, the quality of the obtained titanium powder can meet the TF-2 grade level in YS/T 654—2007 and its particle sizes are close to the laboratory work. In short, the device designed for the post-processing can meet to the pilot scale production requirement.
