目前我国铝电解槽上应用的双插板下料器,风动定量下料器均有下料量误差大的缺点,且生产使用中常发生故障,而风动定量下料器仅适用于砂状氧化铝。沈阳铝镁计设研究院研制的新型点式氧化铝定量下料器(见图)。阀门严实合缝,只要气缸在充气状态下,它就不漏料,因此计量准确,它的计量平均误差<1％,是目前各种定 At present, double flapper feeders and pneumatic quantitative feeders used on aluminum electrolytic cells in our country all have the disadvantage of large feed errors and frequent failures in production and use. The pneumatic quantitative feeders only apply to sand Alumina. Shenyang Al-Mg Design Institute developed a new point-type alumina quantitative feeder (see photo). Valve tightly match, as long as the cylinder in the inflated state, it does not leak material, so accurate measurement, its measurement of the average error of <1%, is the current set
