Abstract
A device for dewatering feedstock that is pourable or free-flowing by compression and segments for use with such a device. A housing has a shell pipe in which a shaft with flights running around its circumference rotates around an axis of rotation. A feedstock is transported through the housing and compressed. The pressate is conveyed out of the device through holes in the shell pipe. An internal pipe is provided within the shell pip. The internal pipe has numerous segments with holes. The outer surface of the segments rests directly on the inner surface of the shell pipe. The holes in the segments overlay the holes in the shell pipe. The segments are made of wear-resistant cast or sintered material.
