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.

Abstract: A separator for separating particulates from a gas stream including: a housing including a first cylindrical chamber defining a curved flow path for the gas stream passing through the separator and a second cylindrical chamber, wherein the first cylindrical chamber is adjacent the second cylindrical chamber and the chambers are separated by a dividing wall; a rotor assembly in the first cylindrical chamber; the first cylindrical chamber having an outer radial zone extending radially between the rotor assembly and the first cylindrical chamber; a flow inlet port to the first cylindrical chamber and a fiber outlet port to the first cylindrical chamber, wherein the inlet port and outlet port are each arranged aligned with the outer radial zone of the first chamber, and wherein the second cylindrical chamber is at a lower pressure such that gas from the gas stream is drawn through the gas passage.
