Thanks to D-shaped vat, the way of generating turbulence in the conventional pulper has been changed, the turbulence is intensified and so the paper bale is quickly soaked into the liquid , in this way the waste paper moving path in pulper is improved and so increasing the production of pulper. It can shorten the pulping time, save energy and increase the specific production in volume.

The high efficient cleaning system of pulper, which consists of an impurities separator and a drum screen, can discharge the heavy impurities from a separately settling box so to protect equipment from damage by heavy partials, and also discharge plastic pieces. It is more suitable for pulping OCC, commercial waste paper continually or in batch.
