These mechanical vibrating screens have been used for decades in the pulp and paper industry fro screening stock in low consistency up to 1.5%.pic21 The stock flows through the feeder against the vibrating screen plate. The accepted fiber passes through the perforation of the screen plate, while the knits and impurities remaining on it carried to the reject outlet. The good fibers, which adhere to the rejects are washed off by a twin water curtain so that the rejects are carried to the reject outlet by the vibratory elliptical motion of the screen through.
The vibrating effect is achieved by imbalanced weight which are fixed to a high speed rotating shaft on both sides. The screen trough is freely carried on spring & elliptically jogged by the rotation of the shaft. The screen plate partially dips into the pond of accepted stock maintained for the cleaning of screen plate by reverse of the accepted stock.
