NEW Pulper Reject Trommel For the the Paper Mill

Published On : 08 Sep, 2010

Croft Paper Machinery Ltd; together with Pen-Cro Ltd , are pleased to announce their NEW Trommel design for paper mill use.

It has been found that many mills world-wide are discarding anything from 30% - 70% of fibres which are attached to the plastic reject coming from pulpers pumped up to the Trommel by a Voith Contaminex or similar pump.

One paper mill disposed of 35 tons of plastic every 24 hours as this went through a normal Trommel fitted with a standard “screw”. On investigating the huge loss of fibres, we recognised that any Trommel made to this design will “Screw” the plastic reject out in 10 to 20 seconds , therefore, not allowing enough time to wash the fibres from the plastic back to the Pulper (the negative drive Trommel can keep the reject in for between 1 and 3 minutes depending on the length and negative angle of the Trommel thus giving enough time to wash most of the fibres from the plastic).

By installing the NEGATIVE ANGLE type Trommel , the client’s 35 tons of plastic fibre reject can be reduced to 28 tons per day, giving the mill the following saving:
35 tons of reject per week with up to 70% fibre content. The negative incline type Trommel can save the mill 7 tons per day of reject and at the same time, return 7 tons of fibre back to the Pulper.

Investment Cost:

It is possible that most mills will be in a position to recuperate the cost of the Trommel within 12 months, by decreasing the fibre loss and reducing the waste disposal costs.
