Inclined Screw Thickener in Pulp Preparation Line

The inclined screw thickener is an essential industrial paper machine designed for washing and thickening various pulp types in preparation for downstream processing. This paper mill plant machinery operates by feeding low-consistency pulp into an inclined trough where gravity initiates dewatering, while a slowly rotating screw conveyor gently transports the thickened pulp upward for discharge. The inclined screw thickener incorporates a specialized brush that rotates in synchronization with the screw, continuously sweeping the filter screen to prevent pore blockage and maintain consistent dewatering performance.

A key advantage of the inclined screw thickener is its gravity-based dewatering mechanism, which consumes significantly less power compared to centrifugal thickeners or vacuum filters. The inclined screw thickener achieves high output consistency, producing pulp suitable for storage, transport, or further processing. With its robust construction, simple mechanical design, and minimal maintenance requirements, the inclined screw thickener offers reliable continuous operation. Available in multiple models with various filtrating areas and motor configurations, the inclined screw thickener can be matched to any production scale.
