剪切力对滤水速率和细小纤维留着率影响的研究

The Study on Effects of Tearing Force on Fine's Retention and Drainage

尝试在DDJ(动态脱水仪 )中用一倒置的圆锥体替代传统的螺旋搅拌器 ,在筛网上形成一个均匀的剪切场。比较了分别使用圆锥体和标准搅拌器时DDJ的滤水速度。分析了剪切力对细小纤维留着率的影响 。

In this paper a new mixture bar will be designed in the DDJ that instead of the traditional bar.Then the drainage rate of fines is compared using the two mixture bar,and analyzed effects of tearing force on fine's retention.At last the feasiasibility and advantage of the new mixture bar will be proved.
