Drilling Perforated Screen Plates for Paper Pulp Making Twin Roll Press

Twin roll press is a kind of highly efficient washing and thickening equipment for continuous dewatering and washing of paper pulp based on the principle of replacement press.

The press chamber of twin roll press has a set of drilling perforated screen plate structure to ensure solid retention and liquid filtration. The material is pushed through the conical screw rotating inside the press chamber. The taper of the screw causes the material to gradually reduce in size as it travels and is subjected to increasing squeezing pressure, thus squeezing the liquid out of it.
