Hot Dispersion System

The screened & deinked stock is fed to the screw press for dewatering purpose and achieves stock consistency of 30%. The dewatered stock is then passed through various screws before entering heating screw.

The stock temperature reaches as high as 120 C and is fed to disc disperser through feeding screw where it is subjected to high shear force by sharpened teethes of dispersing disc and low disc gap of 0.01 mm accuracy achieved by high precision electro hydraulic arrangement. The impurities such as specks, hot melts, stickies etc. get dispersed & drastically improves paper cleanliness.

Principle

Comprises of

  • Screw press

  • Conveying & heating screw 

  • Feeding screw

  • Disc dispersor

  • For final treatment in waste paper recycling pulp mill of writing printing, newsprint, tissue, liner board, and carton board to disperse specks, hot melts, and stickies after fine screening.
     

  • Significant improvement in paper cleanliness & and appearance even with low-grade furnish.
     

  • Improve washability and enable flotation of printing ink released from fibers during dispersion.
     

  • Reduces the problem of stickies and hot melts thereby improving machine runnability.
     

  • Homogeneous mixing of bleaching chemicals.

Screw Press

Medium consistency stock is introduced into the screw and forwarded by the screw. the hole baskets mounted around the screw, retain the fibre mat whereas most of the water is evacuated through the holes. A pneumatically actuated flap creates a counter pressure resulting in the required stock plug which is needed to obtain significant de-watering of the stock. 

Principle

  • Ensures Efficient removal of printing ink, stickies, etc thereby improving the quality of paper.
     

  • Improves brightness and optical cleanliness and removal of stickies and to some extent removal of ash.
     

  • The Ellipse cell floatation system consists of two stages i.e Primary and Secondary stages.
     

  • The primary stage improves brightness and cleanliness while the secondary stage improves the yield.
     

  • Due to two stage system, the goal of maximum ink removal and maximum yield are reached optimally.
     

  • Simple level control loop and high reliability.

Plug Screw 

The floatation Deinking System comprises of series of Primary Cells and Secondary Cells fitted with injector nozzles through which stock is passed. The nozzles are designed in such a way that while the stock is passing vacuum is created which sucks the air into the injector. The injector allows mixing of Air to Pulp and results in micro turbulence that generate wide range of air bubble sizes. Printing inks, stickies etc which are hydrophobic in nature get adhere to these air bubbles and make foam layer which is then separated and collected in a separate foam tank. The collected foam is again treated in Secondary cell for maximum yield.
