The study analyses application possibilities of filtration and thickening models in evaluation of papermaking suspension drainage rate. The authors proposed their own method to estimate the drainage rate on the basis of ...

Gravity dewatering of fibrous suspension is one of basic technological operations in paper production process. Although there are numerous methods to determine dewatering of such suspensions, none of them can measure ...

Based on years of industrial experience and laboratory tests, it was found that highly viscous liquids such as molten polymers, pastes, bitumen, varnishes, pulps, dyestuffs, resins, tar etc. are best mixed by close-clearance ...
